【已解决】Mac中把Python3的pip重新换成Python2的pip

Mac crifan 405浏览 0评论

折腾:

【已解决】Mac本地用supervisor去管理gunicorn的Python3的Flask

期间发现:不知道何时,Mac默认的pip,竟然变成python3的了。

需要重新把Mac本地的实际上是pip3的pip去重新安装回来python2的pip

-》否则后续系统使用pip,也会出现问题的。

感觉像是:

【已解决】Mac本地安装Python3的pipenv虚拟环境

中的:

<code>python3 -m pip install --upgrade --force-reinstall pip
</code>

而把原本是python2的pip,强制安装成python3的pip了?

参考之前的去看看:

<code>➜  robotDemo ll /usr/local/bin/pip*

</code>

貌似好似存在pip的啊

但是为何:

<code>➜  robotDemo which pip
pip: aliased to noglob pip
</code>

?

其他的好像都正常:

<code>➜  robotDemo which pip2
/usr/local/bin/pip2
➜  robotDemo which pip3
/usr/local/bin/pip3
➜  robotDemo which python2
python2 not found
➜  robotDemo which python

➜  robotDemo python --version

➜  robotDemo which python3
/usr/local/bin/python3
➜  robotDemo python3 --version
Python 3.6.4
</code>

mac python3 pip change to python2

python – How to override the pip command to Python3.x instead of Python2.7? – Stack Overflow

好像就是用对应的版本(Python2 or Python3)强制重新安装就可以了?

去试试

<code>python2 -m pip install --upgrade --force-reinstall pip
</code>

结果:

<code>➜  robotDemo python2 -m pip install --upgrade --force-reinstall pip
zsh: command not found: python2
</code>

换成:

<code>python -m pip install --upgrade --force-reinstall pip
</code>

结果:

<code>➜  robotDemo python -m pip install --upgrade --force-reinstall pip
/usr/bin/python: No module named pip
</code>

换成:

<code>python --upgrade --force-reinstall pip
</code>

好像不太对。

pip command is mixed up in python2 and python3 · Issue #50607 · Homebrew/legacy-homebrew

也是说:

<code>python3 -m pip install -U --force-reinstall pip
python -m pip install -U --force-reinstall pip
</code>

需要先去解决:

看来是:

但是明显提示了:

/Users/crifan/Library/Python/2.7/bin

没有在PATH中

但是又不能直接放到PATH中,否则就和之前安装的python3的pipenv冲突了:

很明显,此处之前安装了python2的pipenv,使得:

/Users/crifan/Library/Python/2.7/bin

中有了:

pewtwo

pipenv

pipenv-resolver

virtualenv-clone

但是之前去删除掉python2的pipenv后,是把pipenv从:

/usr/local/opt/python/bin/

去掉了,但是却没有去掉:

/Users/crifan/Library/Python/2.7/bin

残留的那些文件

-》

所以感觉,可以放心的删除掉:

/Users/crifan/Library/Python/2.7/bin

之前残留的和pipenv相关的几个文件了。

但是删除之前,去看看此处的:

/Users/crifan/Library/Python/3.6/bin

中有哪些pipenv相关的文件

<code>➜  robotDemo ls -hl /Users/crifan/Library/Python/3.6/bin

另外,再去看看之前的PATH的路径:

<code>/Users/crifan/Library/Python/3.6/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
</code>

中不同路径下面,和python相关的:

然后去看看:

/usr/local/bin

下面的pip和python:

<code>➜  robotDemo /usr/local/bin/pip --version

再去看看:

下面的pip和python:

<code>➜  robotDemo ll /usr/bin/pip*

还是不行,所以去手动把所用的python解析器改为python2的:

<code>➜  bin /usr/local/bin/pip --version

    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(main())
➜  bin vi /usr/local/bin/pip
➜  bin cat /usr/local/bin/pip

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(main())
</code>

然后再去看看结果pip是否从3变成2的

终于变过来了:

<code>➜  bin /usr/local/bin/pip --version
pip 10.0.1 from /Users/crifan/Library/Python/2.7/lib/python/site-packages/pip (python 2.7)
</code>

然后再去继续重新安装:

不过不论如何,此处新开终端,至少是可以找到python2的pip了:

<code>Last login: Fri Apr 20 14:34:13 on ttys007                                                                                                                                                            ➜  ~ which pip
pip: aliased to noglob pip
➜  ~ where pip
pip: aliased to noglob pip
/usr/local/bin/pip
➜  ~ pip --version
pip 10.0.1 from /Users/crifan/Library/Python/2.7/lib/python/site-packages/pip (python 2.7)
➜  ~
</code>

所以,此处,把pip从python3换成python2的任务,算是完成了。

【总结】

此处,之前的pip,是:

<code>➜  bin /usr/local/bin/pip --version
pip 10.0.1 from /usr/local/lib/python3.6/site-packages/pip (python 3.6)
➜  bin ll /usr/local/bin/pip
-rwxr-xr-x  1 crifan  admin   235B  4 20 15:21 /usr/local/bin/pip
➜  bin cat /usr/local/bin/pip
#!/usr/local/opt/python/bin/python3.6

# -*- coding: utf-8 -*-
import re
import sys

from pip._internal import main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(main())
</code>

即:

从pip是:/usr/local/bin/pip

然后内部是用python解析器:/usr/local/opt/python/bin/python3.6

所以出来的pip –version

是3.6的

最后把:

<code>#!/usr/local/opt/python/bin/python3.6
</code>

改为:

<code>#!/usr/bin/python
</code>

然后再去看看pip就是python2的了:

<code>➜  bin /usr/local/bin/pip --version
pip 10.0.1 from /Users/crifan/Library/Python/2.7/lib/python/site-packages/pip (python 2.7)
</code>

暂时就不深究了。
