最近遇到一个问题。那就是macOS插上NTFS格式的移动硬盘无法读写，然后发现有的文件系统提示被macOS占用无法打开，每次要执行命令手动挂载...然后对于懒癌的我是无法接受的，因此萌生了用Electron开发一个小工具，由于之前用的electron-vuw，内置的是Electron 2.x的版本，不支持macOS黑暗模式，准备尝试使用Electron 7.x，发现是各种安装不上了啊！！

无奈~只有看看源码为啥不行了！发现：Electron 7.0.0以后的版本下载地址多了个字母v，然后安装下载的时候就会404...

解决方法：

npm install -g cross-env
cross-env npm_config_electron_mirror="https://npm.taobao.org/mirrors/electron/" npm_config_electron_custom_dir="7.1.10" npm install

然后就OK了！
