把我的pip和python安装搞砸了

与LinuxMint合作，我昨天用pip安装了一个包

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

好的，安装pip

jason@speedylinux ~ $ sudo apt install python-pip

而且看起来完全没问题。再试一次

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

Complete output from command python setup.py egg_info:

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.

成功

jason@speedylinux ~ $ python get-pip.py

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决定（不要跑）

这显然不是个好主意。当时我不知道

现在是一团糟。 不知道从这里怎么走。我的最终目标是安装bitmex软件包。 下面是一些命令的结果

jason@speedylinux ~ $ python -m pip

任何备受赞赏的帮助

python-pip

都是一个

aptitude

安装包，正如您所看到的，它没有明确链接到python发行版。我要做的是卸载当前的python安装，并使用首选版本重新安装

python get pip.py

应该只在没有本机安装

pip

的版本（即，不是python 3.x）下运行。如果您正在运行python3.x，只需从

tar.gz

或二进制文件重新安装即可。然后，确保python安装是您的linux机器所指向的

显然，您已经混合了Python版本，并安装了一个pip for python3和python2版本。应该是一个更安全的地方吗？我正在使用LinuxMint，我听说一些关键的系统功能在某处依赖于python…？如果您正在使用另一个python安装，是的。对于本机构建，如果您想将其作为答案发布，请编写完整的答案。如果你想完成别人的答案，请考虑在这个答案下面加一个注释。
