Updating the npm-bundled version of node-gyp

Note: These instructions are (only) tested and known to work with npm 8 and older.

Note: These instructions will be undone if you reinstall or upgrade npm or node! For a more permanent (and simpler) solution, see Force-npm-to-use-global-node-gyp.md. (npm 6 or older only!)

Many issues are opened by users who are not running a current version of node-gyp.

npm bundles its own, internal, copy of node-gyp. This internal copy is independent of any globally installed copy of node-gyp that may have been installed via npm install -g node-gyp.

This means that while node-gyp doesn't get installed into your $PATH by default, npm still keeps its own copy to invoke when you attempt to npm install a native add-on.

Sometimes, you may need to update npm's internal node-gyp to a newer version than what is installed. A simple npm install -g node-gyp won't do the trick since npm will still continue to use its internal copy over the global one.

So instead:

Version of npm

We need to start by knowing your version of npm:

npm --version

Linux, macOS, Solaris, etc.

Unix is easy. Just run the following command.

If your npm is version 7 or 8, do:

$ npm explore npm/node_modules/@npmcli/run-script -g -- npm_config_global=false npm install node-gyp@latest

Else if your npm is version less than 7, do:

$ npm explore npm/node_modules/npm-lifecycle -g -- npm install node-gyp@latest

If the command fails with a permissions error, please try sudo and then the command.

Windows

Windows is a bit trickier, since npm might be installed to the "Program Files" directory, which needs admin privileges in order to modify on current Windows. Therefore, run the following commands inside a cmd.exe started with "Run as Administrator":

First we need to find the location of node. If you don't already know the location that node.exe got installed to, then run:

$ where node

Now cd to the directory that node.exe is contained in e.g.:

$ cd "C:\Program Files\nodejs"

If your npm version is 7 or 8, do:

cd node_modules\npm\node_modules\@npmcli\run-script

Else if your npm version is less than 7, do:

cd node_modules\npm\node_modules\npm-lifecycle

Finish by running:

$ npm install node-gyp@latest
