pip3安装不工作 - 没有名为'pip._vendor.pkg_resources'的模块

Question

当尝试使用pip3 install packageName(或sudo pip3 install packageName)安装Python 3的包(在Ubuntu中)时,我收到以下错误消息:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line 33, in vendored
    __import__(vendored_name, globals(), locals(), level=0)
ImportError: No module named 'pip._vendor.pkg_resources'

我已经阅读了几天,并尝试了以下没有任何成功:

1. 使用以下代码卸载并重新安装pip3:sudo apt-get remove python3-pip后跟sudo apt-get install python3-pip.有几个帖子表示有时候pip3Ubuntu没有正确安装.但是,它没有用.
2. 其他帖子暗示这是一个ssl包问题,如果ssl包没有在Python3上加载,那就是问题.但是,以下命令不会引发任何错误:python3 -c "import ssl".
3. 其他一些帖子表明问题出在requests包装上.然后我试着sudo apt-get remove python3-requests跟着sudo apt-get install python3-requests也无济于事.

您可能需要的其他信息:

• pip3 --version 给了我上面报告的相同错误.

• dpkg -L python3-pip 给我以下信息:

注意:pip对于Python2工作得很好.

Answer 1

我在 WSL Ubuntu 上遇到此错误，并且最受欢迎的解决方案对我不起作用。

有效的：

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py --force-reinstall

Answer 2

这解决了我:

curl -sS https://bootstrap.pypa.io/get-pip.py | sudo python3

尝试使用virtualenv为每个不搞乱ubuntu子系统的特定项目.

Answer 3

谢谢@s_s.411

我用以下命令解决了这个问题：

curl -sS https://bootstrap.pypa.io/get-pip.py | sudo python3
type pip3
hash -r
pip3

Answer 4

我遇到了同样的问题，在Ubuntu 16.04上，像你一样使用系统python 3.5.2，像你一样通过apt（）安装pip sudo apt install python3-pip，像你一样在我的主目录中安装了一些软件包pip3 install --user（记录在你与hoefling的聊天中） 。

解决方案如下：

1. 暂时移走所有安装的软件包pip3 install --user：

mv ~/.local/lib/python3.5/site-packages{,_backup}

这pip3又成功了，但我当然想保留这些包。（注意：仅仅搬出去setuptools是不够的；我不确定是哪个包裹造成的。）

2. 将升级后的 pip 安装到主目录中：

pip3 install --upgrade --user pip

现在该pip3命令失败 ( ImportError: cannot import name 'main')，因为它仍然是从当前 shell 中的旧/usr/bin/pip3位置调用的，如 所示type pip3。要解决此问题，请运行：

hash -r

或者，您始终可以退回到打字python3 -m pip而不是pip3。

3. 恢复包：

mv ~/.local/lib/python3.5/site-packages{_backup/*,}
rmdir ~/.local/lib/python3.5/site-packages_backup

4. 现在 pip 正在工作，但python3 -m 'import setuptools'失败了，并出现了与您看到的相同的异常，AttributeError: '_NamespacePath' object has no attribute 'sort'。这可以通过卸载然后setuptools在我的主目录中重新安装软件包来解决（单独卸载是不够的）：

pip3 uninstall setuptools
pip3 install --user --upgrade setuptools

最后，pip3一切都python3 -c 'import setuptools'很好。

Answer 5

没有名为“pip._vendor.packaging”的模块

对我来说，解决方案是卸载系统pipenv（使用包管理器 pacman 安装），然后安装（pipenv由pippacman 管理pyenv）：

pip install pipenv

我跑步时不再有问题pipenv install。
