最近遇到一個問題。那就是macOS插上NTFS格式的移動硬盤無法讀寫，然后發(fā)現(xiàn)有的文件系統(tǒng)提示被macOS占用無法打開，每次要執(zhí)行命令手動掛載...然后對于懶癌的我是無法接受的，因此萌生了用Electron開發(fā)一個小工具，由于之前用的electron-vuw，內置的是Electron 2.x的版本，不支持macOS黑暗模式，準備嘗試使用Electron 7.x，發(fā)現(xiàn)是各種安裝不上了啊??！

無奈~只有看看源碼為啥不行了！發(fā)現(xiàn)：Electron 7.0.0以后的版本下載地址多了個字母v，然后安裝下載的時候就會404...

解決方法：

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！
