no cmake vs compiler found for msversion: 4 (windows7)

Question

apppium-doctor shows opencv4nodejs cannot be found. So I try to install opencv4nodejs with npm -g install opencv4nodejs. But I got this error:

info install opencv version: 3.4.6
info install with opencv contrib: yes

info install
info install executing: git --version
info install git --version: git version 2.22.0.windows.1

I got cmake v3.15 from https://cmake.org/download/. What does log mean? How can I install opencv4nodejs properly?

Answer 1

Try this: npm install --global windows-build-tools --vs2015

Answer 2

Try: npm install -g windows-build-tools before npm install opencv4nodejs
