flutter web之WebSocketChannelException错误
flutter最近新功能增加挺多,试了FFI后,尝试下flutter web,但是执行flutter run -d chrome
时却报如下错误:
~/w/f/flutter_web_demo ❯❯❯ flutter run -d chrome ✘ 1
Launching lib/main.dart on Chrome in debug mode...
Building application for the web...
⣻WebSocketChannelException: WebSocketChannelException:
SocketException:
Failed host lookup: 'localhost' (OS Error: nodename nor servname provided, or not known, errno = 8)⣻^C
报错报的莫名其妙。。。原来没发布时用webdev尝试flutter_web的工程也没有问题啊
网上搜了下,都是一些和我这个完全不搭的问题,只能自己尝试解决了。
仔细看了下报错信息:
Failed host lookup: 'localhost' (OS Error: nodename nor servname provided, or not known
localhost找不到,为什么呢?
忽然想到了今天安装了SwitchHosts!
,然后修改了/etc/hosts。打开/etc/hosts看下内容,果然一篇空白,什么都没有。使用SwitchHosts!
还原默认hosts文件,也就是增加如下内容到hosts:
127.0.0.1 localhost
重新运行flutter run -d chrome
,运行成功,自动打开chrome,完美。
正常输出:
~/w/f/flutter_web_demo ❯❯❯ flutter run -d chrome ✘ 130
