Python 更新错误“模块”对象不可调用后 pip 不再工作

pip no longer working after update error 'module' object is not callable

提问by Agustin

After a pip update, pip has stopped working completely.

pip 更新后，pip 已完全停止工作。

Z:\>pip install matplotlib
Traceback (most recent call last):
  File "c:\program files\python37\lib\runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
  File "c:\program files\python37\lib\runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "C:\Program Files\Python37\Scripts\pip.exe\__main__.py", line 9, in <module>
TypeError: 'module' object is not callable

Any help please?

请问有什么帮助吗？

All credit for this goes to user han_solo, who left the answer as a comment, instead of as an answer:

这一切归功于用户han_solo，他将答案作为评论而不是作为答案：

Instead of pip install stdlib_list --user

代替 pip install stdlib_list --user

use python -m pip install stdlib_list --user

用 python -m pip install stdlib_list --user

Replace stdlib_listwith matplotlibor whatever the name is of the package you want.

更换stdlib_list用matplotlib或任何名称是您想要的包。

I've had the same issue as you, and I solved it uninstalling pip and installing again.

我和你有同样的问题，我解决了它卸载 pip 并重新安装。

To uninstall: python -m pip uninstall pip

卸载： python -m pip uninstall pip

To install, follow the instructions: https://www.liquidweb.com/kb/install-pip-windows/

要安装，请按照说明进行操作：https: //www.liquidweb.com/kb/install-pip-windows/

After that you will going to have a older but functional 19.0.3 version.

之后，您将拥有一个较旧但功能强大的 19.0.3 版本。

回答by mudit

If you do not wish to use the long command every time python -m pip install <package>, reinstall pip to the older version where this error wasn't there.

如果您不想每次都使用长命令python -m pip install <package>，请将 pip 重新安装到不存在此错误的旧版本。

python -m pip install pip==19.0.3

Now you will be able to use pip install matplotlibor pip listnormally.

现在您将能够使用pip install matplotlib或pip list正常。

And whenever the bug is resolved, upgrade pip like you did before.

每当错误解决时，请像以前一样升级 pip。

This worked for me, uninstall pip 19.3.1 and replace with 19.0.3, error gone.

这对我有用，卸载 pip 19.3.1 并替换为 19.0.3，错误消失了。

python -m pip install pip==19.0.3 --user

Have the habit of installing any python packages with pip using python -m, say for installing numpyuse below command:

有使用python -m使用 pip 安装任何 python 包的习惯，比如安装numpy使用下面的命令：

python -m pip install numpy

python -m pip 安装 numpy

In case if it errros out with the environment permission error append --user in the same command:

如果它因环境权限错误而出错，请在同一命令中附加 --user ：

python -m pip install numpy --user

python -m pip install numpy --user

Similar to what @han_solo said, but if your running python3, instead of using:

类似于@han_solo 所说的，但如果您正在运行 python3，而不是使用：

python -m pip install stdlib_list --user

python -m pip install stdlib_list --user

try using:

尝试使用：

python3 -m pip install stdlib_list --user

python3 -m pip install stdlib_list --user

If this is the case you can try to fix it by downgrading the pip version with the following command:

 python -m pip install pip==<previous version>
