I have a angular application: https://github.com/XBITSwitzerland/ngx-admin/tree/ng2-admin

And now I try to do: npm install

But I get this error (The compete Output of the command was way too long, so I just share here the last part):

Does someone have an Idea why this error occurs and how to solve it?

    If you need to install exactly 3.13.1 you will need to downgrade Node.JS to v7 or less Commented Jul 3, 2019 at 12:27

If you run into this issue, read this page: https://www.bramvandenbulcke.be/en/kb/failed-node-sass3131-postinstall-script

The solution in my case:

1) Delete the package-lock.json file

2) npm install gulp-sass --save-dev

3) npm install node-sass@latest

Version specific notes:

[email protected] runs only on versions of Node.js up to v7 as stated in the release notes:

I tried only to delete package-lock.json file and run npm install to whatever the package i want and it worked for me.

I think this is happening because you're missing the node-sass module. Try the following and rerun your build script and see if this resolves your issue:

npm install node-sass@latest

Also, I see you're using fsevents on a Windows platform, just a warning this module is only supported for Native access to OS X FSEvents

I had error [email protected] postinstall: node scripts/build.js on npm install after this message

      try setting a proxy via HTTP_PROXY, e.g.

and spent hours to find solution. I was trying to install it on laravel 5.2 that uses older versions of node and npm this helped me

$ npm install -g n
$ n 6.10.2    // selecting version you need in my case 6.10.2
$ npm install -g [email protected] // same for npm

hope this will help somebody else ^_^

#######UPDATE###########

nvm install 6.10.2
nvm use 6.10.2
npm install -g [email protected]

this was the same issue for me. used nvm to downgrade from v12 to v10.
this was the same issue for me. I was using v10. I downgraded it to v6 and it was working. It is related to the file it tries to download from node-sass, which for v10 was "github.com/sass/node-sass/releases/download/v3.13.1/…", which does not exist ( the files are named linux-x64-{11,14,42,43,44,45,46,47,48,51}_binding.node, but not 64 (or in your case, 72). However, downgrading from v10 to v6 fixed the problem (downgrading to v8 only changed the 64 to 57, which is still not enough).

only delete

package-lock.json

file

and do npm install again

Nope this won't work. Gulp sass needs to be installed to eliminate that specific error.

I also received the same error

"npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! [email protected] postinstall: node scripts/build.js npm ERR! Exit status 1 npm ERR! npm ERR! Failed at the [email protected] postinstall script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above."

Solution:

I increased node-sass and gulp-sass versions to latest in package.json file, then issue got fixed.

If you scroll further up in the error output and you see something like:

gyp verb check python checking for Python executable "python2" in the PATH
gyp verb `which` failed Error: not found: python2

You can fix it on windows with the following steps:

  1. delete node_modules folder
  2. run npm install --global windows-build-toolsin powershell as admin
  3. reinstalling node modules or node-sass with npm install

For me, problem was with the Linux directory permissions. Even with sudo and root user I couldn't make it work.

The solution to me was to change project directory owner as follows:

sudo chown my_user:my_user -R /path/to/project

If you use Visual Studio run following command:

npm cache clean --force
 npm config set msvs_version 2019 --global

where 2019 is the version of Visual Studio

If you are using OpenBSD, that's because you need g++. Install it using

pkg_add g++

But, it gets installed as ec++, on /usr/local/bin, so you can copy, rename, or create a symlink to it using:

ln -s /usr/local/bin/ec++ /usr/local/bin/g++

Do the npm install again and it should work

None of the above worked for me. For different Node versions, different node-saas versions work. My Node version is 10 and I installed [email protected] successfully. Basically below information helped me. Visiting the site and choosing the correct version of node-saas as per the Node version will help a lot.

https://www.npmjs.com/package/node-sass

Warning: LibSass and Node Sass are deprecated. While they will continue to receive maintenance releases indefinitely, there are no plans to add additional features or compatibility with any new CSS or Sass features. Projects that still use it should move onto Dart Sass.

Node 11 4.10+, <5.0 67

Node 10 4.9+, <6.0 64
