How to solve npm install throwing fsevents warning on non-MAC OS?
node.jsJenkinsNpm InstallFseventsnode.js Problem Overview
Following warning is being thrown on npm install command -
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.1.2 (node_modules\rea
ct-scripts\node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@
1.1.2: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"}
)
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules\ch
okidar\node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@
1.1.2: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"}
)
The warning is apparently causing our Jenkins Job to mark failed, so we are just trying to get rid of the same.
I already checked this https://stackoverflow.com/a/42938398/351903 But, unlike what is mentioned there, I do not have any /node_modules/fserrors in my setup. Also, my package.json does not contain fserrors. Following is my package.json -
{

I can see fsevents in the package.json of react-scripts (which is defined under devDependencies of my package.json) in node_modules\react-scripts\package.json -

Update
I tried running the npm install command and getting the exit status of the earlier command. It showed 0 meaning success, despite the warnings. So, it does not look like Jenkins job should be stuck due to this. However, we are still trying to find a way to get rid of this warning because it is not relevant to our OS.
node.js Solutions
Solution 1 - node.js
fsevents is dealt differently in mac and other linux system. Linux system ignores fsevents whereas mac install it. As the above error message states that fsevents is optional and it is skipped in installation process.
You can run npm install --no-optional command in linux system to avoid above warning.
Further information
Solution 2 - node.js
If you want to hide this warn, you just need to install fsevents as a optional dependency. Just execute:
npm i fsevents@latest -f --save-optional
..And the warn will no longer be a bother.
Solution 3 - node.js
npm i -f
I'd like to repost some comments from this thread, where you can read up on the issue and the issue was solved.

Sometimes

So

Solution 4 - node.js
package.json counts with a optionalDependencies key.
NPM on Optional Dependencies.
You can add fsevents to this object and if you find yourself installing packages in a different platform than MacOS, fsevents will be skipped by either yarn or npm.
"optionalDependencies": {
"fsevents": "2.1.2"
},
You will find a message like the following in the installation log:
info fsevents@1.2.11: The platform "linux" is incompatible with this module.
info "[email protected]" is an optional dependency and failed compatibility check. Excluding it from installation.
info fsevents@2.1.2: The platform "linux" is incompatible with this module.
info "[email protected]" is an optional dependency and failed compatibility check. Excluding it from installation.
Hope it helps!
Solution 5 - node.js
I found the same problem and i tried all the solution mentioned above and in github. Some works only in local repository, when i push my PR in remote repositories with travic-CI or Pipelines give me the same error back. Finally i fixed it by using the npm command below.
npm audit fix --force
Solution 6 - node.js
This no longer happens with npm v7. You can update your npm version or update to node v15 or higher, which by default installs npm v7.
Solution 7 - node.js
I also had the same issue though am using MacOS. The issue is kind of bug. I solved this issue by repeatedly running the commands,
sudo npm cache clean --force
sudo npm uninstall
sudo npm install
One time it did not work but when I repeatedly cleaned the cache and after uninstalling npm, reinstalling npm, the error went off. I am using Angular 8 and this issue is common
Solution 8 - node.js
Instead of using --no-optional every single time, we can just add it to npm or yarn config.
For Yarn, there is a default no-optional config, so we can just edit that:
yarn config set ignore-optional true
For npm, there is no default config set, so we can create one:
npm config set ignore-optional true
Solution 9 - node.js
Follow these steps -
- Go to the project's "package.lock.json" file
- Press "Ctrl+F" (to enable search)
- Type "darwin"
- Rename it to 'linux'
Solution 10 - node.js
Do this:
npm install --no-optional
For more info on this go through: https://github.com/npm/npm/issues/11632
Solution 11 - node.js
I'm using, Angular CLI: 8.1.2 Node: 12.14.1 OS: win32 x64
Strangely, this helped me
npm cache clean --force
npm uninstall @angular/cli
npm install @angular/cli@8.1.2
Solution 12 - node.js
For anyone reading it recently, the simplest thing to do on Ubuntu is to install the latest LTS versions of nvm, node.js, and nmp. from version 7 of node.js, these issues have been sorted out.
Refer to this guide: https://computingforgeeks.com/how-to-install-node-js-on-ubuntu-debian/
Solution 13 - node.js
I solved this by deleting the node_modules folder and running npm i.
Solution 14 - node.js
I got the same error. In my case, I was using a mapped drive to edit code off of a second computer, that computer was running linux. Not sure exactly why gulp-watch relies on operating system compatibility prior to install (I would assume it has to do with security purposes). Essentially the error is checking against your operating system and the operating system calling the node module, in my case the two operating systems were not the same so it threw it error. Which from the looks of your error is the same as mine.
The Error
Unsupported platform for fsevents@1.1.3: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})
How I fixed it?
I logged into the linux computer directly and ran
npm install --save-dev <module-name>
Then went back into my coding environment and everything was fine after that.
Hope that helps!
Solution 15 - node.js
run npm install -D vue-loader vue-template-compiler Vue CLI If you are not interested in manually setting up webpack, it is recommended to scaffold a project with Vue CLI instead. Projects created by Vue CLI are pre-configured with most of the common development needs working out of the box.
Follow this guide if the built-in configuration of Vue CLI does not suit your needs, or you'd rather create your own webpack config from scratch.
#Manual Setup #Installation Unless you are an advanced user using your own forked version of Vue's template compiler, you should install vue-loader and vue-template-compiler together:
Solution 16 - node.js
Check your node version and check if the package.json was generate using a different version of node.
I downloaded a repo created from Mac from a Linux and faced this error when trying to npm install. I was using node v14.15.0 and when I switched to v16.13.0, the error disappeared.
Solution 17 - node.js
Yes, it works when with the command npm install --no-optional
Using environment:
- iTerm2
- macos login to my vm ubuntu16 LTS.
Solution 18 - node.js
I had got this error, Linux system(Ubuntu) and This might happen when you run :
> npm install
-
If the project is not present in your localdisk/computer, copy it to your computer and try again. So you get the permission to access folder (Just make sure you have access permission).
-
If you still get some warnings or errors, run:
> npm audit fix
This will solve vulnerabilities in your dependencies and can help you fix a vulnerability by providing simple-to-run npm commands and recommendations for further troubleshooting.
Hope it helps!
Solution 19 - node.js
Switch to PNPM: https://pnpm.js.org/
The fsevents warnings are gone (on Linux).
Even the latest yarn (2.x) shows the warnings.
Solution 20 - node.js
If anyone get this error for ionic cordova install . just use this code npm install --no-optional in your cmd.
And then run this code npm install -g ionic@latest cordova
Solution 21 - node.js
Use sudo npm install -g appium.
