Question

apppium-doctor显示opencv4nodejs cannot be found。因此，我尝试使用opencv4nodejs安装npm -g install opencv4nodejs。但是我遇到了这个错误：

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

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

Answer 1

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

Answer 2

尝试一下：npm install --global Windows-build-tools --vs2015

未找到适用于msversion的cmake vs编译器：4（windows7）
