gyp: Undefined variable module_name in binding.gyp while trying to load binding.gyp

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。

gyp: Undefined variable module_name in binding.gyp while trying to load binding.gyp

github issues  同样的问题，可能生效的不同的方法

----

换了台电脑又遇到了，这次是回退 npm版本解决的问题。

---

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

npm ERR! gyp: Undefined variable module_name in binding.gyp while trying to load binding.gyp
npm ERR! gyp ERR! configure error

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）

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。
