很明显是github无法访问，我首先想到的是docker无法走系统的代理，wsl也不行，通过在docker和wsl中运行curl https://www.google.com可以测试。（fast-whisper镜像不像whiper那样把东西都放进去了，每次运行时还要加载东西，造成这个问题。也就是说whisper官方镜像可以全脱网运行，fast-whisper则不行。）
那么怎么让没有开通局域网共享功能的梯子来分享网络呢？通过一阵子检索，终于发现了二级代理和链式代理这个概念，最终确定用gost试一试。
1 在windows上找到当前的代理
打开网络连接的“网络和Internet设置”，打开设置中的“代理”。如果你安装了某个代理程序，则这里应该能够看到设置的端口。比如地址：http://localhost，端口：15236。
注意，这里的localhost很重要，因为收费的代理不希望你局域网共享，所以限制只能通过localhost访问。如果没有这个限制，那就简单了，直接把代理设置为主机的IP和端口就行了。
2 安装gost作为二级代理
由于我的梯子是在win10上的，所以需要让gost也在win上运行，所以安装了win版的go，然后安装/build这个gost，目录下就有gost.ext了，运行：
.\gost -L=:15230 -F=localhost:15236
二级代理就启动了，最直接的是在另外一台电脑上设置这个IP加端口15230试试，发现代理成功。试了一下，必须是localhost，不能是127.0.0.1。
为了方便，我把这个设置了自动启动，在gost.exe所在目录增加一个名为gost.ps1的文件，内容如下：
.\gost.exe -L=:16236 -F=localhost:15236
同样在这个目录再增加一个gost.bat，内容如下：
Powershell.exe -executionpolicy remotesigned -File ./gost.ps1
然后在gost.bat上右键创建一个快捷方式，把这个快捷方式放到开机启动目录C:\Users\PS\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
可以通过徽标键+R打开shell:startup
3 在wsl中配置代理的启用
然后可以借鉴WSL2配置代理 – Leaos – 博客园 (cnblogs.com)来设置wsl2中的代理。
还有个问题，DNS也要先加上8.8.8.8，不然域名解析被污染了，依然无法访问github。
一个更方便的方法，在wsl的用户主目录增加一个文件proxy.sh，内容如下：
#!/bin/sh
# hostip=$(cat /etc/resolv.conf | grep nameserver | awk '{ print $2 }')
hostip='192.168.0.200'
wslip=$(hostname -I | awk '{print $1}')
port=16236
PROXY_HTTP="http://${hostip}:${port}"
PROXY_SOCKS5="socks5://${hostip}:${port}"
set_proxy(){
export http_proxy="${PROXY_HTTP}"
export HTTP_PROXY="${PROXY_HTTP}"
export https_proxy="${PROXY_HTTP}"
export HTTPS_proxy="${PROXY_HTTP}"
export ALL_PROXY="${PROXY_SOCKS5}"
export all_proxy="${PROXY_SOCKS5}"
git config --global http.https://github.com.proxy ${PROXY_HTTP}
git config --global https.https://github.com.proxy ${PROXY_HTTP}
echo "Proxy has been opened."
test_setting
}
unset_proxy(){
unset http_proxy
unset HTTP_PROXY
unset https_proxy
unset HTTPS_PROXY
unset ALL_PROXY
unset all_proxy
git config --global --unset http.https://github.com.proxy
git config --global --unset https.https://github.com.proxy
echo "Proxy has been closed."
}
test_setting(){
echo "Host IP:" ${hostip}
echo "WSL IP:" ${wslip}
echo "Current https_proxy:" $https_proxy
echo "Current all_proxy:" $all_proxy
echo "Try to connect to Google..."
resp=$(curl -I -s --connect-timeout 5 -m 5 -w "%{http_code}" -o /dev/null www.google.com)
if [ ${resp} = 200 ]; then
echo "Proxy setup succeeded!"
else
echo "Proxy setup failed!"
fi
}
if [ "$1" = "set" ]
then
set_proxy
elif [ "$1" = "unset" ]
then
unset_proxy
elif [ "$1" = "test" ]
then
test_setting
else
echo "Unsupported arguments."
fi
注意，其中的hostip我没有用其他文档给的方法，因为不确定一定对，我改成了本机的固定IP。
然后在.bashrc文件结尾增加
alias proxy="source ~/proxy.sh set"
alias unproxy="source ~/proxy.sh unset"
这样，在source ~/.bashrc之后，就可以直接在shell中输入proxy来启用，或者输入unproxy来停用了。
再进一步，想要在打开shell时自动配置，可以新建一个autoproxy.sh
#!/bin/sh
# hostip=$(cat /etc/resolv.conf | grep nameserver | awk '{ print $2 }')
hostip='192.168.0.200'
wslip=$(hostname -I | awk '{print $1}')
port=16236
PROXY_HTTP="http://${hostip}:${port}"
PROXY_SOCKS5="socks5://${hostip}:${port}"
export http_proxy="${PROXY_HTTP}"
export HTTP_PROXY="${PROXY_HTTP}"
export https_proxy="${PROXY_HTTP}"
export HTTPS_proxy="${PROXY_HTTP}"
export ALL_PROXY="${PROXY_SOCKS5}"
export all_proxy="${PROXY_SOCKS5}"
git config --global http.https://github.com.proxy ${PROXY_HTTP}
git config --global https.https://github.com.proxy ${PROXY_HTTP}
echo "Proxy has been opened."
然后在.bashrc中增加
if [ -f "/home/yourusername/autoproxy.sh" ]; then
. "/home/yourusername/autoproxy.sh"
fi
