npm electron 文档

• npm清除下载缓存 npm cache clean -f
• npm包安装，打印下载列表
  npm install electron --verbose
• electron 安装

1. 代理设置（文件为C:\Users\colin\.npmrc，没有能够本身手动建立）

home=https://npm.taobao.org
registry=https://registry.npm.taobao.org/
sass_binary_site=https://npm.taobao.org/mirrors/node-sass/
phantomjs_cdnurl=https://npm.taobao.org/mirrors/phantomjs
electron_mirror=https://npm.taobao.org/mirrors/electron/

2. 安装命令 npm install electron -g

• 报错：UnhandledPromiseRejectionWarning: Error: EPERM: operation not permitted

1. 手动下载“https://npm.taobao.org/mirrors/electron/7.1.5/electron-v7.1.5-win32-x64.zip” 至“node_modules\electron”
2. 修改文件：node_modules\electron\install.js

//修改前：
// downloads if not cached
downloadArtifact({
  version,
  artifactName: 'electron',
  force: process.env.force_no_cache === 'true',
  cacheRoot: process.env.electron_config_cache,
  platform: process.env.npm_config_platform || process.platform,
  arch: process.env.npm_config_arch || process.arch
}).then((zipPath) => extractFile(zipPath)).catch((err) => onerror(err))

修改后：
// downloads if not cached
zipPath = "./electron-v7.1.5-win32-x64.zip";
extractFile(zipPath)

3. 在node_modules\electron目录下执行node install.js
