没有找到 msversion 的 cmake vs 编译器：4 (windows7)

Question

apppium-doctor 显示opencv4nodejs cannot be found. 所以我尝试opencv4nodejs使用npm -g install opencv4nodejs. 但我收到了这个错误：

info install opencv version: 3.4.6
info install with opencv contrib: yes
info install custom build flags:
info install

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

我从https://cmake.org/download/获得了 cmake v3.15 。日志是什么意思？如何opencv4nodejs正确安装？

Answer 1

试试这个： npm install --global windows-build-tools --vs2015

Answer 2

尝试：npm install -g windows-build-tools之前npm install opencv4nodejs
