npm i bcrypt
新系统拉取项目，下载依赖包，其中包含 bcrypt 依赖，一直安装不成功。
已安装号 Python 3 和 Visual Studio 2019。
此类型npm库都会使用到 node-gyp ，依赖 Python 和 Visual Studio

最终卡在

尝试过清缓存，重装，没用。
npm cache clean -f npm uninstall node-gyp -g npm install node-gyp -g
使用，还是没用
再次尝试，没效果。还是使用了Python 3，卸载了Python 3，程序报错Python2不适用，必须要Python 3。
npm config set python C:\Python27\python.exe
安装 Visual Studio 2017，设置 2017 ，也没用。
npm config set msvs_version 2017 --global
最后到用户目录删除了文件重新安装，成功了。
删除文件：C:\Users\***\AppData\Roaming\npm-cache、C:\Users\***\AppData\Roaming\npm\node_modules\npm、C:\Users\***\AppData\Roaming\npm\node_modules\node-gyp
只剩下了先前安装的 windows-build-tools（使用了管理员shell安装）

在此解决方案中一次生成一个项目。若要启用并行生成，请添加“/m”开关。

感觉本次可能是 管理员权限打开powershell 运行
npm install --global --production windows-build-tools
在起作用。但是其他的尝试可能会在其他时候适用。
