吉普 错误！构建错误 - 如果未定义 npm_config_node_gyp

Question

运行“npm install”后出现这些错误，我运行了“npm install --g --product windows-build-tools”，我还删除了 node_modules、package-lock.json 并安装了 Visual Studio Community 2019但仍然有同样的问题...

C:\Users\myuser\Documents\GitHub\myRepo\node_modules\snappy> if not defined npm_config_node_gyp
"C:\Users\myuser\Documents\GitHub\myRepo\node_modules\npm-lifecycle\node-gyp-bin\\..\..\node_modules\node-gyp\bin\node-gyp.js" rebuild )
 else (node "C:\Program Files\nodejs\node_modules\npm\node_modules\node-gyp\bin\node-gyp.js" rebuild )
Building the projects in this solution one at a time. To enable parallel build, please add the "-m" switch.

我使用的 Nodejs 版本是：v12.8.1 和 NPM 版本：6.10.2

运行“npm install”后我应该怎么做才能消除该错误？

我建议在管理模式下使用 power-shell 命令安装依赖项 npm install --global windows-build-tools
