安装ELectron失败解决方案

npm安装Electron解决方案

Electron使用npm安装时，因为是国外的镜像源，所以速度会非常慢。而使用cnpm如下命令进行安装时，又会出现安装失败的问题：

npm install electron -g
execute post install 1 scripts...
[1/1] scripts.postinstall electron@6.0.3 run "node install.js", root: "C:\\Users\\94012\\AppData\\Roaming\\npm\\node_modules\\electron"

C:\Users\94012\AppData\Roaming\npm\node_modules\electron\install.js:49
  throw err

从报错原因上，发现是找不到这个版本的electron，然后返回404了。

Downloading tmp-1428-0-electron-v6.0.3-win32-x64.zip
Error: GET https://cdn.npm.taobao.org/dist/electron/6.0.3/electron-v6.0.3-win32-x64.zip returned 404

所以找到原因就好说了，那就指定之前的版本安装即可，如：

cnpm install electron@^6.0.1 -g
