如何 pip 卸载使用 git 项目 URL 安装的包？

Question

我尝试按照 BlueJeans 会议 REST API (https://github.com/bluejeans/api-rest-meetings/tree/master/libs/python) 的安装说明使用命令

pip install git+https://github.com/bluejeans/api-rest-meetings.git@pip-repo

pip freeze 命令确认我已经安装了它：

Kurts-MacBook-Pro-2:~ kurtpeek$ pip freeze
BlueJeansMeetingsRestApi==1.0.0
certifi==2018.4.16
python-dateutil==2.7.3
six==1.11.0
urllib3==1.23

但是，在 iPython shell 中，我无法导入 BlueJeansMeetingsRestApi：

Kurts-MacBook-Pro-2:~ kurtpeek$ ipython
Python 3.6.5 (v3.6.5:f59c0932b4, Mar 28 2018, 05:52:31) 
Type 'copyright', 'credits' or 'license' for more information
IPython 6.2.1 -- An enhanced Interactive Python. Type '?' for help.

In [1]: import BlueJeansMeetingsRestApi
---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-1-0891de0c20ce> in <module>()
----> 1 import BlueJeansMeetingsRestApi

ModuleNotFoundError: No module named 'BlueJeansMeetingsRestApi'

这是在我的本地环境中，但我也将它安装在 Pipenv 环境中，在这种情况下，我需要提供一个 egg，我通过将 #egg=BlueJeansMeetingsRestApi 附加到 Git 项目 URL 来完成。如果我立即执行此操作，我会得到“已满足要求”：

Kurts-MacBook-Pro-2:~ kurtpeek$ pip install git+https://github.com/bluejeans/api-rest-meetings.git@pip-repo#egg=BlueJeansMeetingsRestApi
Requirement already satisfied: BlueJeansMeetingsRestApi from git+https://github.com/bluejeans/api-rest-meetings.git@pip-repo#egg=BlueJeansMeetingsRestApi in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (1.0.0)
Requirement already satisfied: urllib3>=1.15 in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from BlueJeansMeetingsRestApi) (1.23)
Requirement already satisfied: six>=1.10 in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from BlueJeansMeetingsRestApi) (1.11.0)
Requirement already satisfied: certifi in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from BlueJeansMeetingsRestApi) (2018.4.16)
Requirement already satisfied: python-dateutil in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from BlueJeansMeetingsRestApi) (2.7.3)

因此，我想尝试先卸载 BlueJeans 并指定 egg 重新安装它。但是，如果我尝试使用相同的项目 URL 卸载它，我会收到以下错误：

Kurts-MacBook-Pro-2:~ kurtpeek$ pip uninstall git+https://github.com/bluejeans/api-rest-meetings.git@pip-repo
You must give at least one requirement to uninstall (see "pip help uninstall")

顺便说一句，我使用的是 Python 3.7.0（pip 是 pip3 的别名）。

我有两个问题：

1. 为什么import BlueJeansMeetingsRestApi 一开始就不起作用？
2. 如何卸载它？

Answer 1

要卸载一个包，只需使用

pip uninstall BlueJeansMeetingsRestApi

如果 IPYTHON 存在一些配置问题，您可能会遇到此类错误。

但是如果你时间不够，我建议你直接使用 python shell 命令 shell，我认为当你尝试将它导入文件时这应该可以工作。

python <filename>.py

请检查并告诉我。

Answer 2

总结CoderRambo 和tgikal 的回复，是的，我能够以这种方式卸载BlueJeansMeetingsRestApi：

Kurts-MacBook-Pro-2:~ kurtpeek$ pip uninstall BlueJeansMeetingsRestApi
Uninstalling BlueJeansMeetingsRestApi-1.0.0:
  Would remove:
    /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/BlueJeansMeetingsRestApi-1.0.0-py3.7.egg-info
    /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/BlueJeansMeetingsRestApi/*
    /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/test/*
Proceed (y/n)? y
  Successfully uninstalled BlueJeansMeetingsRestApi-1.0.0

然而，问题的根源在于 iPython 在 Python 3.6 上运行，而 BlueJeans 安装在 Python 3.7 上。我通过使用which ipython 确认了这一点：

Kurts-MacBook-Pro-2:~ kurtpeek$ which ipython
/Library/Frameworks/Python.framework/Versions/3.6/bin/ipython

我跑了pip install ipython，现在它指向Python 3.7：

Kurts-MacBook-Pro-2:~ kurtpeek$ which ipython
/Library/Frameworks/Python.framework/Versions/3.7/bin/ipython

然后我重新安装了 BlueJeans REST API（没有指定鸡蛋），现在我可以导入它了：

Kurts-MacBook-Pro-2:~ kurtpeek$ ipython
Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 26 2018, 23:26:24)
