Npm install cannot find module 'semver'

I can't use npm install using the command prompt in NodeJS. I'm getting these errors when running npm install:

module.js:339
    throw err;
    ^
Error: Cannot find module 'semver'
    at Function.Module._resolveFilename (module.js:337:15)

    at Module.require (module.js:366:17)

I had the same error. npm uninstall npm -g, rm -rf node_modules didn't help me, because when I tried I was getting Error: Cannot find module 'semver'. But I solve my problem with these steps (this will delete other global modules you may be using):

• sudo rm -rf /usr/local/lib/node_modules
• sudo rm -rf ~/.npm
• brew uninstall --force node
• brew install node

Hope this will help those who are getting a similar problem.

I'm facing the same issue here.

If this occurs right after you run brew install yarn try running yarn global add npm and voilà - fixed!

if you are in Linux server exit from the server and re ssh

On MS Windows, the solution is to remove %APPDATA%\npm and reinstall node

I had this too, after running brew install yarn yesterday. At least, everything was fine up until then.

I ran rm -rf node_modules and tried to reinstall, but no npm command was working.

In the end I took the rather simple step of reinstalling Node via the official Node installer for Mac OS X.

https://nodejs.org/en/download/

Everything is fine now. Just went back to the directory, ran npm install and it's done the trick.

On Ubuntu, if you would rather manage Node through the default repositories using apt, it's best to install both nodejs and npm this way.

It's very likely that the version of npm you are using is expecting semver in a specific place that is not aligned with the version of Node JS you have installed. If there is only one version of nodejs and only one version of npm, and they are both installed using the default repositories, this should work perfectly.

Here is my best guidance for getting Node and npm working using the main Ubuntu repositories:

0. sudo apt-get purge nodejs --auto-remove and sudo apt-get purge npm --auto-remove
1. whereis node: remove all the versions of node, one at a time. Repeat until this command returns a blank after node:.
2. sudo apt-get install nodejs
3. node --version: should return ... no such file or directory
4. nodejs --version: should return v1x.x.x. This is the version installed by apt. It will probably be less recent that the latest version available on the Node JS website.
5. sudo apt-get install npm
6. npm --version: it will use the nodejs installed by apt and work correctly.

On Arch Linux what did the trick for me was:

sudo pacman -Rs npm
sudo pacman -S npm

Having just encountered this on Arch Linux 4.13.3, I solved the issue by simply reinstalling semver:

pacman -S semver

I had the same problem, the way i solved it was by executing

PATH="$PATH"

in terminal, problem was the terminal kept the old path of nodejs instead of using the new one.

Actually, it is taking the reference of previously stored modules.

Solution:Delete the npm-cache/npm folder in the installation directory of nodejs. In windows, it is in C:/User/Username/Appdata/Roaming/npm(or npm_cache). and try to install again.

Same thing to do in any OS.

In my case on macOS(10.13.6), when I executed the following command

npm install -g react-native-cli

I got this error

Error: Cannot find module 'semver'

    at tryModuleLoad (internal/modules/cjs/loader.js:593:12)
    at Function.Module._load (internal/modules/cjs/loader.js:585:3)

The error got resolved after executing the command

yarn global add npm

proposed by @Ashoor

For me, this happened after I installed yarn globally. To resolve this issue, install npm using yarn and done.

yarn global add npm

On Windows, downloading Node's MSI again and doing a 'Repair' worked for me.

I had the same issue but it was caused by a broken package-lock.json file.

Deleting package-lock.json and running npm install again fixed it for me.

Just make sure semver is installed: npm install -g semver

sudo rm -rf /usr/local/bin/npm /usr/local/share/man/man1/node* ~/.npm
sudo rm -rf /usr/local/lib/node*
sudo rm -rf /usr/local/bin/node*
sudo rm -rf /usr/local/include/node*

sudo apt-get purge nodejs npm
sudo apt autoremove

Then install node and npm

Just uninstall node js then reinstall it using nvm. Your problem will be solved. I am a debian 10 user.

mahedi@debain:~$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash

after executing the command. close your terminal and reopen then run this command to install node js latest version.

mahedi@debain:~$ nvm install v14.15.5

now check by typing node -v

This worked for me on Ubuntu (latest version dated Oct/2020)

I had to first get code from the bash source:

curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -

This got the latest version of node which updated my libraries and got rid of the 'semver' error.

For arch linux

sudo pacman -Rsc -n nodejs
sudo pacman -Sy nodejs
sudo pacman -Sy npm

I got same error and I solved it.

delete package-lock.json file and node_modules folder then npm install

Faced this issue when I ran npm install using a lower version of node. Then later when I upgraded to latest version of node and ran gulp, it has shown this error.

To resolve, deleted node_modules and re-ran npm install. Then gulp ran fine.

Just remove the /node_modules folder and try again. ;)

You can use npm rm to remove it.

You can also check this issue on GitHub. To be more specific about unnistal, try to follow this:

> Uninstalling > > So sad to see you go. > > sudo npm uninstall npm -g Or, if that fails, > > sudo make uninstall More Severe Uninstalling > > Usually, the above instructions are sufficient. That will remove npm, > but leave behind anything you've installed. > > If you would like to remove all the packages that you have installed, > then you can use the npm ls command to find them, and then npm rm to > remove them. > > To remove cruft left behind by npm 0.x, you can use the included > clean-old.sh script file.

I finally figured this out! Yes, you have to uninstall/delete all files and reinstall. BUT SOME OF THE FILE PATHS ARE TOO LONG TO DELETE DURING THE UNINSTALL PROCESS. The file paths are so long in Node that they may not be able to be deleted. You have to rename the file paths.

After uninstalling Node, use Command Prompt, navigate to ...\Appdata\roaming\ (use the path from the error message). Try to delete the folder with del npm. Then, if it doesn't allow you to delete a folder, start renaming the folders in the file path in the next error message to "a" or something short. You may have to do this for multiple folders along the path. Then you should be able to delete! Then reinstall node and it should work.

just remove your node_modules

rm -rf node_modules

than

yarn

or

npm install

Just a reminder of executable npm execute via node env:

xb@dnxb:/tmp$ type -a npm
npm is /usr/bin/npm
npm is /bin/npm
xb@dnxb:/tmp$ realpath /usr/bin/npm /bin/npm
/usr/share/npm/bin/npm-cli.js
/usr/share/npm/bin/npm-cli.js
xb@dnxb:/tmp$ 
xb@dnxb:/tmp$ head -1 /usr/share/npm/bin/npm-cli.js
#!/usr/bin/env node

I can check which node is chosen by type -a, the first line has the most priority, i.e. I can get same error if I run /usr/local/bin/node /usr/share/npm/bin/npm-cli.js, but no error if I run /usr/bin/node /usr/share/npm/bin/npm-cli.js:

xb@dnxb:/tmp$ type -a node
node is /usr/local/bin/node
node is /usr/bin/node
node is /bin/node
xb@dnxb:/tmp$ realpath /usr/local/bin/node
/usr/local/bin/node
xb@dnxb:/tmp$ realpath /usr/bin/node
/usr/bin/node
xb@dnxb:/tmp$ realpath /bin/node
/usr/bin/node
xb@dnxb:/tmp$ 

There are 2 unique node exe based on realpath. If you have the similar case, then you need to find out how to remove the undesired/broken node exe, e.g. sudo rm /usr/local/bin/node or manipulate env $PATH.

In my case, simply re-running brew install yarn fixed the problem.

I faced with same trouble after brew installs yarn on my MacOs Sierra 10.12.6. (And the first try of installation fall after brew update self with a message " Homebrew must be run under Ruby 2.3! You're running 2.0.0. (RuntimeError)". So I re-run it.)

So I use n manager to reinstall npm.

• switch to another node version (for my case to 8.0) by "n" command with empty parameters
• or install new by "n x.x.x" where x.x.x the node version number (i need 6.9.1)
• delete working version by "n rm x.x.x" where x.x.x the node version number. use sudo if need
• install working version by "n x.x.x" where x.x.x the node version number. use sudo if need
• switch by to the working version of node. (see first step for reference)

I think the trouble can be caused that node was installed under sudo for case.

I had the same issue installing on AWS Linux. I had to install it with sudo. So to get around this I followed step 3 from this article (making sure to get the latest version of node)

https://www.hostingadvice.com/how-to/update-node-js-latest-version/

wget https://nodejs.org/dist/vx.x.x/node-vx.x.x-linux-x64.tar.xz
tar -C /home/aUser/node --strip-components 1 -xJf node-vx.x.x-linux.x64.tar.xz

But installed it to the user's home directory /home/aUser/node. Then added that path to my PATH.

export PATH=/home/aUser/node/bin:$PATH

After that I was able to do an npm install with no issues.

I faced this issues while running project on higher version of cli. To solve this issue you can simply comment out @angular-devkit/build-angular module and again you have to reinstall it through

> npm install @angular-devkit/build-angular --save

For me, it happened while upgrading to gulp 4 from gulp 3 in my project. So, when I run "gulp watch" command, it was throwing me same error.

It's probably due to version mismatch as compared to my globally installed gulp.

So, either upgrading gulp with "-g" global flag would help, or else I followed this below

However, I used "./node_modules/.bin/gulp watch" in my project. This ensures that all the dependencies that gulp needs are taken from node_modules only.

i was getting an error saying Permission Denied after running any 'ng' command (ng --version). I googled for a while and tried clearing npm cache npm cache verify, uninstalling my global angular cli (npm uninstall -g @angular/cli) and reinstalling Angular/cli (npm install -g @angular/cli) etc.. but it would give an error say its already installed. but the node_modules folder here wouldn't have any angular folder.. reinstalled node even then restarted my computer.

ANSWER: Finally I found that the ng.cmd and ng.ps1 files in C:\Users\JaGoodwin\AppData\Roaming\npm\ here were still there (in npm folder).. even though I did npm uninstall -g @angular/cli. those files were causing ng (angular/cli) to think it was still installed. i deleted those files then npm install -g @angular/[email protected] (version i need) I then removed my projects node_modules and then ran npm install and now can run my angular project using ng serve.

C:\Users\JaGoodwin\AppData\Roaming\npm\

Find this by folder searching %APPDATA% in your windows search bar.

Start fresh.

brew uninstall --force node
brew install node

Just delete (or rename) the cloned repository's version of semver folder: "gitClonedRepository/App/node_modules/semver"

and copy the "semver" folder from "C:\Program Files\nodejs\node_modules\npm\node_modules\semver"

into the application's node_modules folder.

(if you're on Windows, othervise it must be located somewhere in /usr/local/lib/node_modules).

Just check your preinstall scripts if you have one. Sometimes to restrict the versions of node and npm one needs to run a project.

If that's the case you need to install semver manually via npm install -g semver
