在Ubuntu18.04中安装升级pip3并使用socks代理

本文最后更新于：November 21, 2019 pm

ubuntu18.04中自带了python3但是缺少了pip3，这里我们使用apt来进行安装，然后使用pip3自己对自己升级，再安装对应的socks依赖包，这样在系统使用了socks代理的时候能够使用代理下载各种包，有效提高速度。

# 使用apt安装pip3
# 需要注意的是python3-pip和python-pip是不一样的，前者是python3而后者是python2
sudo apt-get install python3-pip

# 使用apt安装的版本很旧，大概是9.0+，我们将它升级到最新
sudo pip3 install --upgrade pip

# 这里顺便附上卸载pip3的命令
sudo apt-get remove python3-pip

# 安装socks所需要的依赖
sudo apt install qt5-qmake qtbase5-dev libqrencode-dev libappindicator-dev libzbar-dev libbotan1.10-dev
sudo pip3 install pysocks

最后我们随便安装一个包来确定一下下载安装的速度
