Windows 上的 node-gyp 5：找不到 npm\\node_modules\\node-gyp\\bin\\node-gyp.js

Question

Running npm 6.11.3, node-gyp 5.0.3, VS2019 on Windows 10 v1903, getting this error:

Cannot find module %AppData%\\npm\\node_modules\\node-gyp\\bin\\node-gyp.js (where %AppData% is expanded to the actual user-specific path).

The error only happens if the build is invoked via npm, ie:

npm run build

The package.json file scripts section:

"scripts": {
  ...
  "build": "node-gyp build",
}

If node-gyp build is invoked manually outside npm context, the error is gone.

How do I get rid of the error and still use npm scripts for making builds?

Answer 1

Figured it out.

After upgrading to node-gyp 5 on a Windows 10 build system, I started getting the infamous Error: Cannot find module ... npm\\node_modules\\node-gyp\\bin\\node-gyp.js , caused by node_modules\\npm-lifecycle\\node-gyp-bin being pushed on top of my PATH by npm, exactly as described here .

None of the existing remedies I've found and tried could solve this issue for me, including installing the latest windows-build-tools . Here's exactly what I tried, in the following order:

• manually clean up the mess and duplicates in System PATH and User PATH environment vars
• reboot
• choco unistall nodejs
• rd /s %AppData%\\npm\\
• rd /s %AppData%\\npm\\
• choco install nodejs
• npm install -g npm@latest
• npm install -g node-gyp@latest
• npm install -g typescript@latest

I was still getting the missing node-gyp.js error. What did help was to properly set npm config set node_gyp to point to the correct node-gyp.js , as suggested here . Yet somehow the script from that thread didn't work properly for me (as well some other PowerShell/Batch scripts I tried).

Eventually, I've come up with the following PowerShell 6 one-liner that did the trick for me :

pwsh -Command npm config set node_gyp "`u{22}$(Join-Path $(npm root -g) -ChildPath 'node-gyp\bin\node-gyp.js')`u{22}"

Hope this helps others and future-me. I'd still recommend going through the above bullet list for clean troubleshooting.
