关于pip:AttributeError-module-socks-has-no-attribute-create

当运行 pip install $PAK_NAME 时，显示如下谬误：

ERROR: Exception:

狐疑是之前配置的全局代理的起因，查看~/.bashrc，在底部发现之前增加代码如下：

export TERM=xterm-256color
export all_proxy="socks5://127.0.0.1:51342"

故，采取以下操作：

正文掉 all_proxy，如 #export all_proxy="socks5://127.0.0.1:51342"
运行 unset all_proxy

胜利解决，前面某个工夫又呈现此问题，执行步骤 2 unset 全局代理即可！
