node.js Solutions

Solution 1 - node.js

The easy solution is just switch from the "bcrypt" npm module to bycryptjs or bcrypt-nodejs. It's the exact same API, but pure JS so no native add-ons to deal with.

npm install --save bcryptjs && npm uninstall --save bcrypt

Then change your require calls to "bcryptjs", but all your code otherwise can be unchanged.

Long term, I suspect at the moment bcrypt may not be ready for node v0.12.0 yet, but if not it will eventually be updated and ready.

Solution 2 - node.js

For windows install the following module:

npm install -g node-gyp
npm install --g --production windows-build-tools

Then try to install:

npm install bcrypt

Solution 3 - node.js

On this command:

npm install --g --production windows-build-tools

You may have to run this in Powershell as administrator on your Windows machine.

You do that by right-clicking on Powershell and select "Run As Administrator"

Solution 4 - node.js

The accepted solution works, but bcryptjs is slower than python and C++ version.

If you still want bcrypt instead of bcryptjs, working solutions are the commands below, but they can also have their own problems.

✔️ npm install -g node-gyp
❌ npm install --g --production windows-build-tools

In Windows, the second command will try to install Visual Studio along with python and hence the problem arises because the Visual Studio installation takes a lot of time. Also it also hinders the installation of python. If you forget to run those commands as Administrator, then they will get installed at C:\Users\User.windows-build-tools which will still not work because node will search for python in C:\ or C:\Program Files. Hence these commands in some cases may increase your complications.

So the best idea for you is to ✔️install python manually for All Users. It is not necessary to add python to the environment path.

Then run:

✔️ npm install -g node-gyp

Now you are ready to install bcrypt:

npm install bcrypt

Solution 5 - node.js

Upgrade to [email protected]

npm i [email protected]

I am not getting errors on this newer version of bcrypt, older version gave different types of errors ranging from not able to install bcrypt to typescript type errors

Solution 6 - node.js

I just ran the following then tried the install and it worked:

npm install node-pre-gyp -g

Solution 7 - node.js

I was facing the same issue on the server side( aws ubuntu 16.04).

I tried deleting node_module/bcrypt by sudo rm -rf node_module/bcrypt multiple times and reinstalled it again and again by various ways but still facing the same issue.

I checked node version with nvm and it was also showing stable (v10.11.0).

Finally, I tried.

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

and it worked for me.

Solution 8 - node.js

On Mac OS, after a Xcode update, running sudo gcc and accepting Xcode's new license solved the problem!

Solution 9 - node.js

If you are on windows run powershell as administrator and use these commands.

npm install --g --production windows-build-tools

and then install bcrypt using

npm install --save bcrypt

Solution 10 - node.js

Reason for Error : Node maybe can’t able to find the Python path on your system

Solution

step: 1 Rum command prompt as administrator step 2 Install the package

  npm install --global --production windows-build-tools

It may take some while, keep patient

step 3 Now install

npm install node-gyp

Last step Now you are ready to Go

npm install bcrypt

Solution 11 - node.js

I was also having the same problem. The following commands helped me.

npm rebuild

then

npm install bcrypt

Solution 12 - node.js

I managed to solve this by running the command: sudo apt-get install -y build-essential python and then yarn add bcrypt.

You can find the instructions here:

https://github.com/kelektiv/node.bcrypt.js/wiki/Installation-Instructions

https://github.com/kelektiv/node.bcrypt.js

Solution 13 - node.js

I installed bcrypt-nodejs though it's already deprecated, and then removed it and installed bcrypt again. Like this, I Installed bcrypt successfully and it worked fine.

yarn add bcrypt-nodejs
yarn remove bcrypt-nodejs
yarn add bcrypt

Solution 14 - node.js

if any of the above fails to work, do:

npm install node-gyp

Afterwards visit the official python download site Official Python download link

Install the latest version of python, make sure to check add python to path

After installation, do:

npm --save install bcrypt

Solution 15 - node.js

Running

sudo apt install build-essential

installs all the tools you need to install bcrypt on Linux. Then you can run

npm install

Solution 16 - node.js

I had node version 12.18.3 and fixed the same by running npm i [email protected]

Solution 17 - node.js

This happened to me as I was installing a package from github that had an older version of bcrypt as a dependency. I just uninstalled the old bcrypt version and installed the newest version:

    npm uninstall bcrypt
    npm install bcrypt

Then, voila. It worked.

Solution 18 - node.js

Had the same problem. Updating npm and try again (npm install -g npm usually). It fix the issue for me.
