This has just been fixed. You should uninstall and reinstall again. Sorry for the inconvenience.

[PacejetRepository]

I did all that and nothing happened?

[hansl]

What version do you see with ng version?

[hansl]

Not sure what to tell you, but it works locally here. It seems you are installing @angular/core. If you do npm list, what does it say?

[hansl]

I feel this is a case where you are in a directory with an invalid node_modules.

[PacejetRepository]

What do you mean? Now i get this error

[PacejetRepository]

you can close this now. I reverted back to v6.9.1 LTS and all my initial problems are gone. Please next time don;t release something that you haven't tested as working.

[jmesa-sistel]

@hansl @PacejetRepository
I have the same issue using node 7.1.0
Why is this closed?
I have had to revert back to v6.9.1
At this moment angular-cli is not compatible with node 7.1.0
I am using windows 10

[jbeja]

I have this very same issue on Windows 10.

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules\chokidar\node_modules\fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"}) npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules\browser-sync\node_modules\chokidar\node_modules\fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

After that installation stops.

[jonasschulte]

And the same issue on Ubuntu 16.04:

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules/chokidar/node_modules/fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})

[tforster]

Folks, I am here after googling the same error as it pertains to setting up Swagger tools. I believe it is because I am running npm install inside the Linux Subsystem for Windows which is relatively new to Windows 10. My hypothesis is that the particular module is confused between the host OS (Windows 10) and the filesystem (Linux). @jonasschulte @jbeja @PacejetRepository are you running npm in cmd, Powershell, Git bash or LSW? Trying to see if we have a consistent pattern.

[WilfredLemus]

The same issue on Deepin 15.3 x64 node v7.1.0. I reverted back to node v6.9.1 and same issue.

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules/ionic/node_modules/chokidar/node_modules/fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})

[Freddessson]

Looks similar to my warnings (node v6.9.4):
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules\angular-cli\node_modules\chokidar\node_modules\fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"}) npm WARN @angular/[email protected] requires a peer of rxjs@^5.0.1 but none was installed.

[michaelAdewunmi]

This is similar to the warning I had too while trying to install browser -sync. I am using a windows 10 and node version 6.9.5.

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules\browser-sync\node_modules\chokidar\node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"ia32"})

is there any way to correct the problem in order to clear the warning?

[ngooide]

same goes here.
node v7.2.1
ubuntu 14.04

[Danilo-Araujo-Silva]

Same here:
node v7.6.0
Ubuntu 14.04.5 LTS

How to solve this? I'd appreciate a clean install without any issues.

[ghost]

any update?

[tolawho]

Same here:
node v7.7.1, npm 4.1.2
windows 10 x64
...

Resolved: add option _--no-optional_ at the end of command.

[Adesubomi]

Please someone should come out and help out on this issue. Its screwing with my time...
node v7.6.0, npm 4.4.1

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules/chokidar/node_modules/fsevents):

[tolawho]

@Adesubomi see my comment above.

[lisa13]

Anyone? :(

[tolawho]

@lisa13 add option --no-optional at the end of command.

[chekkanaveen]

@lisa13 try this command
npm install -g angular-cli

[lisa13]

@chekkanaveen I have installed the latest angular version: npm install -g @angular/cli
but no use!

[lisa13]

@tolawho Thanks I tried that as well, no changes so far! I am uninstalling everything and reinstalling again. If this doesn't work either I am changing my OS :/

[saiyaff]

Still facing this issue after the @angular/cli v.1.0.0. What is actually causing this error?

[dvk2591]

I have node v6.10.0 on my windows 7 machine. I am getting the below eror in the output window when I try to save package.json file.
Error:

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules\chokidarnode_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"ia32"})
npm WARN @ngtools/[email protected] requires a peer of typescript@^2.0.2 but none was installed.

I am unable to load gulp tasks due to this.

Please help me resolve this issue.

[vprasanth]

Node version: 7.7.3
NPM: 4.1.2
ng-cli: 1.0.0

Same issue:

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules/chokidar/node_modules/fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})

[interaminense]

I was able to work by going back to the 2.15.11 version of npm

[Danilo-Araujo-Silva]

Although that I have the same issue, as I pointed above, for me is just a non clean install.
Everything works without problem.

I'm using, for now, npm 4.2.0, node 7.8.0, n 2.1.6.
