Question

与linux mint合作，昨天我去了pip安装一个软件包。

user@mycomp ~ $ pip install bitmex-ws
The program 'pip' is currently not installed. You can install it by typing:
sudo apt install python-pip

好，安装点子

jason@speedylinux ~ $ sudo apt install python-pip

看来一切正常。再试一次...

jason@speedylinux ~ $ pip install bitmex-ws
Collecting bitmex-ws

Complete output from command python setup.py egg_info:
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named setuptools
You are using pip version 8.1.1, however version 18.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

认为这是最后一个错误的问题（但实际上实际上只是未安装setuptools），就像上面说的那样...

user@mycomp ~ $ pip install --upgrade pip
Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    from pip import main
ImportError: cannot import name main

在这一点上，我很沮丧，做了很多谷歌搜索和搜索。最终在以下情况下这样做：

jason@speedylinux ~ $ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

成功。

jason@speedylinux ~ $ python get-pip.py
/tmp/tmpM7KfNh/pip.zip/pip/_vendor/requests/__init__.py:83: RequestsDependencyWarning: Old version of cryptography ([1, 2, 3]) may cause slowdown.

    Uninstalling pip-18.0:

Consider using the `--user` option or check the permissions.

这看起来很奇怪。所以我做了不明智的选择（不要运行）

sudo python get-pip.py

这显然不是一个好主意。当时不知道。

那回来了

现在它搞砸了。不知道该怎么走。我的最终目标是安装该bitmex软件包。这是一些命令的结果

jason@speedylinux ~ $ python -m pip

/usr/local/lib/python2.7/dist-packages/pip/_vendor/requests/__init__.py:83: RequestsDependencyWarning: Old version of cryptography ([1, 2, 3]) may cause slowdown.
  warnings.warn(warning, RequestsDependencyWarning)

Usage:   
  /usr/bin/python -m pip <command> [options]

Commands:
  install                     Install packages.
  download ... etc

jason@speedylinux ~ $ pip
bash: /usr/bin/pip: No such file or directory
jason@speedylinux ~ $ which python
/usr/bin/python
jason@speedylinux ~ $ which python3
/usr/bin/python3
jason@speedylinux ~ $ which pip
/home/jason/.local/bin/pip
jason@speedylinux ~ $ pip
bash: /usr/bin/pip: No such file or directory
jason@speedylinux ~ $ pip install bitmex-ws
bash: /usr/bin/pip: No such file or directory

任何帮助，谢谢

Answer 1

如您所见，

python-pip是一个安装了aptitude的软件包，没有明确链接到python发行版。我要做的是卸载当前的python安装，然后使用您喜欢的版本重新安装。

python get-pip.py仅应在未本地安装pip的版本（即，不是python 3.x）上运行。如果您正在运行python3.x，只需从tar.gz或二进制文件重新安装。然后，确保linux盒子指向的是python安装。

通常pip-install打包时，您会希望python -m pip install...确保没有使用apt安装的pip

此外，如果您使用的是Linux，我认为您应该考虑以下事项

sudo apt update

sudo apt upgrade

搞砸了我的pip和python安装
