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 -

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.
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
https://github.com/npm/npm/issues/14185
https://github.com/npm/npm/issues/5095
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.
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.
This is exactly Angular's issue. Current package.json requires fsevent
as not optionalDependencies but devDependencies. This may be a problem
for non-OSX users.
Sometimes
Even if you remove it from package.json npm i still fails because
another module has it as a peer dep.
So
if npm-shrinkwrap.json is still there, please remove it or try npm i
-f
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 "fsevents#1.2.11" 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 "fsevents#2.1.2" is an optional dependency and failed compatibility check. Excluding it from installation.
Hope it helps!
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
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.
Follow these steps -
Go to the project's "package.lock.json" file
Press "Ctrl+F" (to enable search)
Type "darwin"
Rename it to 'linux'
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
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
Do this:
npm install --no-optional
For more info on this go through: https://github.com/npm/npm/issues/11632
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
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/
I solved this by deleting the node_modules folder and running npm i.
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!
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:
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.
Yes, it works when with the command npm install --no-optional
Using environment:
iTerm2
macos login to my vm ubuntu16 LTS.
I had got this error, Linux system(Ubuntu) and This might happen when you run :
npm install
1) 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).
2) 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!
Switch to PNPM: https://pnpm.js.org/
The fsevents warnings are gone (on Linux).
Even the latest yarn (2.x) shows the warnings.
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
Use sudo npm install -g appium.

How to update Ember packages?
The official upgrade docs are here: ember-cli upgrade. Details are in release notes.
First of all, there are some distinct steps:
Setting up the global ember-cli
Upgrading the project ember version
Upgrading the all other addons
You should better to do them step-by-step.
By the way, look all the release notes of the releases you've passed through. Because there may some differences. For example, for older versions (2.14, 2.13..) there were bower cache clean and bower install steps. For new versions (2.15), those steps are not necessary.
Don't use npm. Use yarn. It's faster, more secure and has better cache. It's also recommended as migration path from Bower (by Bower). Yarn is also recommended by Ember team instead of npm.
rm -rf node_modules
yarn
Use yarn to selective package update
yarn upgrade-interactive --latest
I have a repository containing a package.json which contains scoped dependencies. I also have an .npmignore file intended to whitelist all files and subdirectories in dist/. The problem is all of the scoped dependencies are included when running npm install #private/a another repository. This includes both private npm packages and public packages such as #uirouter.
package.json:
{
"name": "#private/a",
"version": "1.0.0",
"description": "",
"main": "dist/index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"repository": {
"type": "git",
"url": "git+ssh://git#bitbucket.org/private/a.git"
},
"author": "",
"license": "ISC",
"homepage": "https://bitbucket.org/private/a#readme",
"devDependencies": {
"gulp": "^3.9.1",
"gulp-angular-embed-templates": "^2.3.0",
"gulp-concat": "^2.6.1",
"gulp-jshint": "^2.0.4",
"gulp-rename": "^1.2.2",
"gulp-sass": "^3.0.0",
"gulp-uglify": "^2.0.0",
"jshint": "^2.9.4"
},
"dependencies": {
"#private/b": "^1.0.0",
"#private/c": "^1.0.0"
}
}
.npmignore
**
!dist/**
Despite these two files when I run npm install #private/a --save within another repository it is installing the dependency along with all it's scoped dependencies:
/node_modules/#private/a/dist/index.js
/node_modules/dist/css/styles.css
/node_modules/#private/a/node_modules/#private/b
/node_modules/#private/a/node_modules/#private/c
package.json
It should only be this:
/node_modules/#private/a/dist/index.js
/node_modules/dist/css/styles.css
package.json
How can I achieve this? I have tried different variations of the .npmignore but have not had any luck.
.npmignore is irrelevant to what you are trying to do. This file only decides which parts of your npm package code ends up in npm registry. So it is working as advertised.
Your problem must be in your npmconfig or because of using an older version of npm. The latest version installs stuff as so:
/node_modules/#private/a/dist/index.js
/node_modules/#private/b/...
/node_modules/#private/c/...
package.json
I have verified that this is happening with latest npm. But there used to be a time when npm installed dependencies into a nested structure. See this for example. So I suggest:
Making sure you have latest node and npm.
Making sure your npm config is not forcing legacy bundling. Run npm get legacy-bundling. Make sure this is false.
There are few cases where the nesting of dependencies happens legitimately even with the latest npm. See this. But I am guessing your problem is not due to this. You can test by simply doing npm install #private/a in an empty folder.
Node will install your package files along with all the dependencies declared under dependencies field.
How the dependencies tree is build, depends on which version of npm do you use.
If your package doesn't need those dependencies to run, it means they are just dev dependencies and you can safely list them under devDependencies field.
Dev dependencies are only installed when you run an npm install inside the plugin directory.
You need to lock your dependency. You might want to check out npm shrinkwrap.
There is connect-assets in my package.json's dependencies. And its package.json looks like:
"dependencies": {
"connect-file-cache": "0.2.4",
"mime": "1.2.2",
"snockets": "1.3.6",
"underscore": "1.1.7"
},
"devDependencies": {
"async": "0.1.14",
"coffee-script": "~1.3.1",
"connect": "1.8.5",
"nib": "0.2.0",
"bootstrap-stylus": "0.2.0",
"nodeunit": "0.5.4",
"stylus": "0.22.2",
"request": "2.1.1",
"watchit": "0.0.4",
"less": "1.3.0"
}
But when I ran npm install(with or without --dev and --dev-all), it only installed connect-assets, no stylus, nib, etc.
How should I do?
It's simply because the npm should not work this way. If I want to install the devDependencies of some depended modules, I have to enter their directories.
One should be aware that npm will not deliver files that are specified in the .npmignore file. This might be the culprit if one was looking to use files in a devDependency that exist in the git repo, but mysteriously are not present in the npm delivery.
