今天在公司拉下项目link的时候，react native报了这样的错误
1.Error log：
E:\project\my\scanner-qrcode-master\node_modules\metro-config\src\defaults\blacklist.js:38
return new RegExp(
^
SyntaxError: Invalid regular expression: /(.*\\__fixtures__\\.*|node_modules[\\\]react[\\\]dist[\\\].*|website\\node_modules\\.*|heapCapture\\bundle\.js|.*\\__tests__\\.*)$/: Unterminated character class

解决方法：
进入node_modules\metro-config\src\defaults 编辑 blacklist.js
/node_modules[/\\]react[/\\]dist[/\\].*/ 修改为 /node_modules[\/\\]react[\/\\]dist[\/\\].*/
