error when "npm install"

[parazitenew]

Hi,
I'm on Win7 x64, I have:
node 8.9.4
npm 5.6.0
node-gyp 3.6.2
opencv installed and env. variables declared:
OPENCV_DIR = C:\opencv\build\x64\vc14
OPENCV_INCLUDE_DIR = C:\opencv\build\include
OPENCV_LIB_DIR = %OPENCV_DIR%\lib

I downloaded this zip in my project folder. then I run "npm install" and got this error:

KeyError: '2017'
gyp ERR! configure error

When I use "npm start", the app runs with console error that say can't find module 'opencv4nodejs' . Inside "node_modules" there is no "opencv4nodejs" folder. that means it could not be installed. So I tried to do it manually by downloading the whole opencv4nodejs plugin (21MB) from here https://github.com/justadudewhohacks/opencv4nodejs#how-to-install , and put it inside node_modules, then I run "npm start", this time the console said "can't find module ../build/Release/opencv4nodejs.

I also tried this:

node-gyp rebuild

but it throwed error too:

module.js:540
    throw err;
    ^

Any idea? Thanks.

Hey,

The first error you posted KeyError: '2017' is a node-gyp issue with VS 2017 on windows. If you run npm config get can you verify that msvs_version = "2017" is set? Otherwise do npm config set msvs_version=2017. The issue you posted seems to be the same as: nodejs/node-gyp#1179.

The second log you posted when running node-gyp directly seems strange to me. Looks like a path issue, but after fixing that one you will probably run into the other issue as well.

Hi, thanks for the answer.

npm get config return this:
msvs_version = "2017"

Going to close this, as it is an issue with node-gyp and msvs2017.
