How to include the path for the node binary npm was executed with

Question

Windows, VSC, Running npm start got this

npm WARN lifecycle The node binary used for scripts is C:\Program Files\nodejs\node.exe but npm is using C:\somewhere\AppData\Roaming\npm\node_modules\node\bin\node.exe itself. Use the --scripts-prepend-node-path option to include the path for the node binary npm was executed with.

I understand it means my local version is diff from the one in the PATH variable (C:\Program Files...). How do proceed to tell it to use --scripts-prepend-node-path?

I played a trick by replacing the C:\Program Files\nodejs with C:\somewhere\AppData\Roaming\npm\node_modules\node\bin in PATH variable, it does pick up that new node.exe got but there is no node binary in the current PATH. Again recommend to use the --scrip ts-prepend-node-path option to include the path for the node binary npm was executed with

Answer 1

Like I said, replacing the actual path in PATH system variable didn't fix the problem completely, it still complained about binary is missing. Found this solved the there is no node binary in the current PATH problem. Restored the original PATH, tried it worked.

Simply create a file at the root folder of the app, called .npmrc, place this line into it:

scripts-prepend-node-path=true

Answer 2

Here's another way that works: npm config set scripts-prepend-node-path auto

Conflict between your node binary and your npm

---

In case the error looks something like:

npm is trying to use the same node as the one it use to run itself.

resolve this conflict by adding the node directory to your PATH:

npm config set scripts-prepend-node-path true

From the npm documentation:

npm run sets the NODE environment variable to the node executable with which npm is executed. Also, if the --scripts-prepend-node-path is passed, the directory within which node resides is added to the PATH

Having this issue in Visual Studio 2017, I instead told VS to always use the NodeJS that I had installed from nodejs.org rather than the frozen-in-time one that ships with Visual Studio. (The one that shipped with VS2015 is so ancient it doesn't really work anymore.)

In Visual Studio, go to TOOLS > OPTIONS > search for EXTERNAL WEB TOOLS > and ensure "C:\Program Files\nodejs" (or wherever nodejs.org installed it) is first in the list of paths, adding it if necessary.

For WebStorm, invalidating caches and restarting worked for me.
