Question

Answer 1

I have come across this same issue in the past. Here is the solution. You may need to restart your machine several times to clear all the errors.

Solution:

1. Install Install VC++ Build Tools  2017 and while installing select V140 from the side menu

2. Install Python 2.7, and add it to your PATH

3. npm config set python python2.7 --global

4. npm config set python C:\Python27\python.exe --global

5. npm config set msvs_version 2015 --global

6. set VCTargetsPath=C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140


**Note:  If you still face error > most likely the problem is node-sass is not installed** 

After this step you have to restart your machine

7. Install the latest versions of Python

8. As Admin:
$ cd "C:\Program Files\nodejs\node_modules\npm"
$ npm install node-gyp

9. $ npm config set msvs_version 2015 --global

Note: that I have VS 2017, but configuring it as ver 2017 won't work. Not sure why.

    10. As Admin:
$ npm install -g node-sass

And finally, one last check:
$ node-sass -v

Hope it helps.

Answer 2

I turned off the automatic update from visual studio of npm's packages

Answer 3

After spending more than 3 days finally found the solution at https://spin.atomicobject.com/2019/03/27/node-gyp-windows/

It worked when I ran "npm install -no-optional" The -no-optional flag ensures that npm installs only the required packages.

A quick note : I followed all the steps listed in https://github.com/nodejs/node-gyp#on-windows and finally ran "npm install -no-optional"

Answer 4

I did the same. I'm still getting errors. Is there anyone who can help

• npm -v = 6.10.3
• node -v = v12.10.0
• python -V = Python 2.7.16
• node-sass -v =(first line) node-sass 4.12.0 (Wrapper) [JavaScript]
• node-sass -v =(second line) libsass 3.5.4 (Sass Compiler) [C/C++]
• node-gyp -v = v5.0.3

Answer 5

Simple fix worked for me is:

I installed Python 3.7 and installed Visual Studio version 2017 from https://my.visualstudio.com/Downloads?q=visual%20studio%202017

Also installed recommended updates.

And then I set npm config set msvs_version 2017 --global.

Answer 6

It's node version problem. I'm currently on the latest feature version (Current Version). The newer node is not supported yet. To solve the problem, you could switch to LTS version which is normally fully supported.

Easy switch would be (If you are using brew):

brew unlink node

and then link the node lts verion (right now is node@12) as the following:

brew install node@12 && brew link --overwrite node@12 --force

That solved for me.
