pip3安装不工作 - 没有名为＆＃39; pip._vendor.pkg_resources＆＃39;

时间：2018-03-25 17:13:40

标签： python-3.x ubuntu pip

尝试使用pip3 install packageName（或sudo pip3 install packageName）安装Python 3（在Ubuntu中）的软件包时，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'

我已经阅读了好几天，并尝试了以下内容但没有取得任何成功：

  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。有些帖子表示有时pip3无法正确安装Ubuntu。但是，它没有用。
  2. 其他帖子表明这是一个ssl包问题，如果ssl包没有加载到Python3上，那就是问题所在。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包中。然后我尝试了sudo apt-get remove python3-requests，然后sudo apt-get install python3-requests也无济于事。

    4. 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向我提供了以下信息：

    如何让pip3工作？

    注意：Python2的pip工作正常。

    编辑：

    1. 在Python3中尝试import setuptools时，出现以下错误：
      2.     Traceback (most recent call last):

      1. 在终端中运行以下命令sed -n '31,37p' < /usr/lib/python3/dist-packages/pip/_vendor/__init__.py时，我得到以下内容：

        __import__(modulename, globals(), locals(), level=0)
    except ImportError:

        2. ===========================================

        EDIT2：

        我的python3 --version是Python 3.5.2。

        运行代码ls /usr/lib/python3/dist-packages获得的已安装软件包列表。

7 个答案:

答案 0 :(得分：11)

这为我解决了问题

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

尝试对每个特定项目使用virtualenv，而不要弄乱ubuntu子系统。

答案 1 :(得分：2)

<块引用>

没有名为“pip._vendor.packaging”的模块

基本上解决方案是卸载系统 pipenv 并从我的本地 pipenv 安装 pip，该系统由 pyenv 管理。

执行此操作后，我在运行 pipenv install 时不再遇到问题。

答案 2 :(得分：1)

我也有同样的问题，我通过此命令解决了。

pip uninstall pkg-resources==0.0.0

答案 3 :(得分：1)

感谢@ s_s.411

我通过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

答案 4 :(得分：1)

我在Ubuntu 16.04上遇到了同样的问题，使用像您这样的系统python 3.5.2，并通过apt（{sudo apt install python3-pip）像您一样安装了pip，并在我的主目录中安装了{{ 1}}，就像您一样（记录在your chat with hoefling中）。

解决方案如下：

  1. 暂时移走所有pip3 install --user安装的软件包：
pip3 install --user

这使mv ~/.local/lib/python3.5/site-packages{,_backup} 再次工作，但是我当然想保留包装。 （注意：仅移出pip3是不够的；我不确定是哪个软件包引起的。）

  1. 在主目录中安装升级后的pip：
setuptools

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

type pip3

或者，您总是可以退回到键入hash -r 而不是python3 -m pip。

  1. 还原软件包：
pip3
  1. 现在pip正在运行，但是mv ~/.local/lib/python3.5/site-packages{_backup/*,} rmdir ~/.local/lib/python3.5/site-packages_backup 失败，但出现了与您看到的相同的异常python3 -m 'import setuptools'。可以通过卸载然后在我的主目录中重新安装AttributeError: '_NamespacePath' object has no attribute 'sort'软件包来解决（单独卸载是不够的）：
setuptools

最后，pip3 uninstall setuptools pip3 install --user --upgrade setuptools 和pip3很好。

答案 5 :(得分：0)

我尝试了此页面上的所有修复程序，但没有成功，最后我发现我的virtualenv损坏了，我不得不像这样重新安装virtualenv

deactivate-为安全起见先停用
virtualenv --python=/usr/bin/python3.8 /path/to/my_virtualenv_python3
source /path/to/my_virtualenv_python3/bin/activate-激活环境

当然，如果您不使用3.8版，则将/path/to/my_virtualenv_python替换为您自己的路径，将python3.8替换为自定义版本的python：）

还请注意，这可能会或可能不会删除已安装的软件包，因此只需重新安装以后需要的每个requirements.txt。

答案 6 :(得分：0)

我知道这是一个老问题，但我在 WSL Ubuntu 上遇到了这个错误，而且投票最多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
