Category: Npm install stuck at fsevents

Some of the JavaScript tool libraries didn't load so I went back into Solution Explorer to see if there was a problem and I saw this weird error that said or at least, I read it as "npm not installed.

Midi triads

I also ran "where" to see where and how many npm was installed. This looks OK as two of those npms are shell scripts and not run on Windows. Just to make sure you have the version of npm you want, Felix made a VERY useful npm-windows-upgrade utility that you run like this, ironically with npm.

I've used this tool many times with success. It also lets you choose the exact version you want and it's very smart. However, then I realized that Visual Studio wasn't saying that npm wasn't installed, it was saying a dependency in the npm tree below wasn't installed. That hyphen - is intended to mean something. For the record, I think this is not intuitive and is a poor UX. Perhaps it should say "package s not installed" but you get the idea now. I started manually opening the tree up one item at a time looking for the bad package - while quietly swearing to myself - until I realized that the Solution Explorer tree nodes are searchable.

This is UX issue number two, for me. I think the "broken" library should also include the BANG!

Regardless, now I know I can quickly do a string search. I dropped out to the command prompt into to the project's folder and run " npm ls " to see an ASCII tree that effectively is the same tree you see in Visual Studio. Looks like fsevents is a package that is only used on OSX, so it's an optional dependency that in the case of Windows is "unmet.

Perhaps it's more an "INFO" or perhaps, one could argue, it doesn't need to be shown at all on Windows. A quick google shows that, well, the entire world is asking the same thing.

So much so that it got pretty heated in this GitHub Issue asking a similar question. Here's where it gets super interesting.

Visual Studio consider it from their point of view needs to keep things consistent so it tests with, and ships with, a version of npm. Again, this makes sense. That way when working in a large group we can all be sure we're on the same version of stuff.

When you get a new version of the Web Tools for Visual Studio, presumably this version of npm gets updated.


This also means that unless you tell Visual Studio otherwise, the npm and node you get when running a build in VS is gonna be different than if you do it outside - if you stick with the default settings. I added my node installation like this and made sure it was at the top. Then I right click on npm and Restore Packages and all is right with the world as now I'm using npm 3. The Output Window for 3.

Actually I think VS is calling an npm library, rather than shelling out and parsing the " npm ls --json " payload, but you get the idea.

The change I made affects all Visual Studio projects on my machine, forever. Maybe I need to be smarter? Maybe Visual Studio is already being smart. Note the second option there in the list? It's pointing to. Ah, I can just add specific version of npm to packages.

How can I be sure it's ignoring that relative path?It was only ever intended to fix a specific error message which has since been fixed.

I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that. Installing node through Homebrew can cause problems with npm for globally installed packages.

To fix it quickly, use the solution below. An explanation is also included at the end of this document.

This solution fixes the error caused by trying to run npm update npm -g. Once you're finished, you also won't need to use sudo to install npm modules globally. Before you start, make a note of any globally installed npm packages. These instructions will have you remove all of those packages. After you're finished you'll need to re-install them.

Node and npm should be correctly installed at this point.

If you're a Homebrew user and you installed node via Homebrew, there is a major philosophical issue with the way Homebrew and NPM work together. If you install node with Homebrew and then try to do npm update npm -gyou may see an error like this:.

There's an NPM bug for this exact problem. The bug has been "fixed" by Homebrew installing npm in a way that allows it to manage itself once the install is complete. However, this is error-prone and still seems to cause problems for some people. The root of the the issue is really that npm is its own package manager and it is therefore better to have npm manage itself and its packages completely on its own instead of letting Homebrew do it.

Also, using the Homebrew installation of npm will require you to use sudo when installing global packages.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

It only takes a minute to sign up. I've been trying to npm install Bootstrap and Font-Awesome on an Angular application. Should be a routine job with no problems. Now, I'm getting errors like this. It would appear that the root of this issue is centered around the fsevents package that npm is trying to install. This is indicated in other reports on this issue in other places. I went back to the drawing board. It turns out that when I looked at the github issue closer, someone actually nailed the root cause with this handy little tidbit.

This is not something to be "fixed". There no longer are credentials for AWS. So the installs are actually a bit risky. In addition 1. Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered.

I can see fsevents in the package. I tried running the npm install command and getting the exit status of the earlier command. It showed 0 meaning success, despite the warnings.
