今天安裝electron的時候，遇到以下問題，一直waiting...
electron的版本是@8.2.3
Building fresh packages...
[-/5] ⠐ waiting...
[-/5] ⠐ waiting...
[3/5] ⠐ electron
[4/5] ⠈ phantomjs-prebuilt
[5/5] ⠈ electron-chromedriver
解決步驟：
1、首先想到的是切換到國內源
yarn config set registry https://registry.npm.taobao.org -g
yarn config set sass_binary_site http://cdn.npm.taobao.org/dist/node-sass -g
發現還是不行。。。
2、於是使用npm/cnpm，發現一遍通過。。。
3、然後又試了網上說的在項目目錄下創建.npmrc或.yarnrc（npm安裝就建立.npmrc）文件，發現然並卵
registry "https://registry.npm.taobao.org"
sass_binary_site "https://npm.taobao.org/mirrors/node-sass/"
phantomjs_cdnurl "http://cnpmjs.org/downloads"
electron_mirror "https://npm.taobao.org/mirrors/electron/"
sqlite3_binary_host_mirror "https://foxgis.oss-cn-shanghai.aliyuncs.com/"
profiler_binary_host_mirror "https://npm.taobao.org/mirrors/node-inspector/"
chromedriver_cdnurl "https://cdn.npm.taobao.org/dist/chromedriver"
4、然後還有的說使用yarn install --no-bin-links，還是不行
5、最後將electron版本改爲@6.1.10或者@6.0.0，成功！
yarn install
yarn install v1.22.4

暫時還沒找到原因。。
