Flutter 安装

使用系统Mac OS

已经没办法给大家看问题了,我在github上提了问题.

github issue

使用命令 command

`flutter doctor`

异常:
exception

SocketException: SocketException: Connection failed (OS Error: No route to host, errno = 65), address = android.googlesource.com, port = 443

总的来说就是下载 Downloading Gradle Wrapper...的时候连接不到外网,以至于失败

github上的这位小哥提醒了我@lishuhao

@eseidelGoogleit's reachable via https from Chrome
Maybe his chrome use proxy but terminal not use proxy.

我确实开了ss,但是终端确实连接不到代理的,不走代理,那当然无解

解决:

1.Mac下使用Homebrew安装

brew install polipo

2.修改配置

ln -sfv /usr/local/opt/polipo/*.plist ~/Library/LaunchAgents

vim /usr/local/opt/polipo/homebrew.mxcl.polipo.plist

在配置文件中添加
socksParentProxy=localhost:1086

其中1086这个端口号,自己去看

3.启动

launchctl load ~/Library/LaunchAgents/homebrew.mxcl.polipo.plist

4.使用

$ http_proxy=http://localhost:8123 curl ip.gs
Current IP / 当前 IP: 47.90.88.133
ISP / 运营商:  ALIYUN
City / 城市:  Hong Kong
Country / 国家: China
IP.GS is now IP.SB, please visit https://ip.sb/ for more IP information, ip.gs will only use for curl purpose. / IP.GS 已更新至 IP.SB 请访问 https://ip.sb/ 获取更多信息, ip.gs 域名仅作 curl 使用
Please join Telegram group https://t.me/sbfans if you have any issues. / 如有问题，请加入 Telegram 群 https://t.me/sbfans

可以看到,现在我是香港的IP了,http_proxy=http://localhost:8123这个是提供默认的,至于怎么修改我没有看,也不知道

把代理设置为全局的
