2. 解决

2.1 可能一

删除目录下的 node_modules 文件夹，再次 npm install 即可。

  • 原因：如果直接是从别处复制过来的项目，项目已有的 node_modules 文件夹，因此会造成兼容性冲突。

2.2 可能二

参见 github 上关于解决 node-gyp rebuild 的方案。

  • Option 1
    Install all the required tools and configurations using Microsoft’s windows-build-tools using npm install --global --production windows-build-tools from an elevated PowerShell or CMD.exe (run as Administrator).

  • Option 2
    Install tools and configuration manually:
    Install Visual C++ Build Environment: Visual Studio Build Tools (using “Visual C++ build tools” workload) or Visual Studio 2017 Community (using the “Desktop development with C++” workload)
    Launch cmd, npm config set msvs_version 2017
