Node-gyp version is different when using npm install

When I run

npm install -g ffi -verbose

it raises error, and log suggests node-gyp version is 8.2.0:

...
npm ERR! D:\Programs\NodeJS\node_global_modules\node_modules\ffi\node_modules\ref\src\binding.cc(644,8): warning C4996: 'Nan::ForceSet': ������Ϊ�ѷ�� [D:\Programs\NodeJS\node_global_modules\node_modules\ffi\node_modules\ref\build\binding.vcxproj]

This is different from what I see when running node-gyp -v:

C:\Users\Administrator>node-gyp -v
v8.4.1

and could possibly explain why it uses python 3.8 and MSVC 2019 even though I have already run:

npm config set python python2.7
npm config set msvs_version 2015

I don't know why there is another node-gyp on my PC, and how to use the proper version.

gyp node-gyp npm node.js

Type where node-gyp

You can have a globally installed node-gyp which you probably do and also each package can carry its own version which is probably the case with ffi The PATH determines which one will run

So interesting find, I thought I'd share it here. I was also facing a similar situation where my global node-gyp was 9.0.0 and I had updated the npm node-gyp too like mentioned here . I was using

  • node 16.2.0
  • npm 7.15.1
  • node-gyp 9.0.0

When I ran npm install @abandonware/bleno I got the following error and thought it was npm using the wrong node-gyp version.

But then I saw this comment here and here so I went back to look at the log file and saw that the actual error started above here (line 409)

So I downgraded my node version using nvm from 16.2.0 to 14.17.1 (and this also downgraded my npm version to 6.14.13) and viola! My npm install worked just fine.
