Can't Install node-sass with Visual Studio 2019

Question

I'm having an issue installing node-sass on my project. ít's installed globally, but for some reason my Angular project says it can't find the module.

When trying to install it as a dev dependency I get an error, I notice a particular line that says:

npm ERR! gyp verb find vs2017 Found installation at: C:\Program Files (x86)\Microsoft Visual Studio\2019\Community

Is the only solution installing VS2017?

Full logs can be found below.

I've tried running with --unsafe-perms param and it didn't work either.

Answer 1

I had the exact samme error. It seems as if it is an issue with Visual Studio 2019.

I removed Visual Studio 2019 and installed Visual Studio 2017 instead.

After that, I had no problem installing node-sass.

Answer 2

According to node-sass github page, supported node.js version vary release by release.

enter link description here

try:

sudo npm install --save-dev  --unsafe-perm node-sass
