Issue using node-sass after updating NodeJS

Question

I get an issue using node-sass after updating my NodeJS version.

Issue :

(node:472) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version.
C:\aglqng\src\main\webapp\node_modules\node-sass\lib\index.js:15
    throw new Error(errors.missingBinary());
    ^

Error: Missing binding C:\aglqng\src\main\webapp\node_modules\node-sass\vendor\win32-x64-48\binding.node
Node Sass could not find a binding for your current environment: Windows 64-bit with Node.js 6.x

Found bindings for the following environments:
  - Windows 64-bit with Node 0.12.x

This usually happens because your environment has changed since running `npm install`.
Run `npm rebuild node-sass` to build the binding for your current environment.

I tried this and it doesn't work :

I encountered the issue when I updated to VS 2017. VS comes with its own installation of Node, which might not be the most updated one that exists on your system. To override this follow the following steps:

1. Go to Tools -> Options -> Project and Solutions -> Web Package Management
2. In "Location of External Tools" Add a new entry which points to nodejs install location, like: "C:\Program Files\nodejs"
3. Make sure it is above other entries.

I found a really helpful article here, which informed me on above points.

[Note: If needed, first update nodejs on your system. On windows, this is done by making a fresh install of new version.]

I had the same issure as your. When I used npm rebuild node-sass, it was still failed, the error gyp ERR! stack Error: Can't find Python executable "python", you can set the PYT HON env variable.

I searched the error message, some npm plugins need node-gyp to be installed. However, node-gyp has it's own dependencies.node-gyp

On Windows
Install all the required tools and configurations using Microsoft's windows-build-tools using npm install --global --production windows-build-tools from an elevated PowerShell or CMD.exe (run as Administrator).

npm install --global --production windows-build-tools

and then install the package

npm install --global node-gyp

That's it, run npm rebuild node-sass again, and it's worked!

I have this error when code repository is originally complied in macOS Mojave, and run it on Windows 10.

Just use following command to fix this error:

npm rebuild node-sass

After run the command, then run ng serve again.

Answer 6

Some versions of node-sass are not compatible with certain versions of Node. After I upgraded my Node to version 12, I had to upgrade the version of node-sass in my project to 4.12 using this command:

npm install node-sass@4.12.0

This page shows the version compatibilities:
