'npm install: Failed at the node-sass@3.13.1 postinstall script
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?
Solution 1:[1]
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 node-sass@3.13.1 postinstall: node scripts/build.js on npm install after this message
> node scripts/install.js
Downloading binary from https://github.com/sass/node-sass/releases/download/v3.13.1/linux-x64-72_binding.node

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 npm@3.10.10 // same for npm
hope this will help somebody else ^_^
#######UPDATE###########
nvm install 6.10.2
nvm use 6.10.2
npm install -g npm@3.10.10
Solution 3:[3]
only delete
package-lock.json
file
and do npm install again
Solution 4:[4]
I also received the same error
"npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! node-sass@3.13.1 postinstall: node scripts/build.js
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the node-sass@3.13.1 postinstall script.

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:
- delete
node_modulesfolder - run
npm install --global windows-build-toolsin powershell as admin - 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
Solution 7:[7]
Do the following commands respectively:
rm -rf package-lock.json
npm install node-sass@latest
Solution 8:[8]
For Ubuntu
Delete the package-lock.json file
sudo npm install gulp-sass --save-devsudo npm install node-sass@latest
Solution 9:[9]
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
Solution 10:[10]
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
