看来你已经卸载了 pip 皮普 在bash中默认为蟒蛇的 皮普 . 这是因为默认情况下,蟒蛇会在 .bashrc 看起来像这样:

# added by Anaconda3 5.3.1 installer
# >>> conda init >>>
# !! Contents within this block are managed by 'conda init' !!
# [some stuff]
# <<< conda init <<<

然后重启终端, 皮普 python

# before commenting stuff out in .bashrc
$ which python
/home/username/.anaconda3/bin/python
$ which pip2
/home/username/.anaconda3/bin/pip2

# after commenting stuff out in .bashrc and restarting
$ which python
/usr/bin/python
$ which pip2
/usr/bin/pip2

要安装pip,请安全下载 get-pip.py

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

然后运行以下命令:

python get-pip.py
