Python 未找到“pip==7.1.0”分发版，应用程序需要此分发版

The 'pip==7.1.0' distribution was not found and is required by the application

提问by Arnold Laishram

I have the latest version of pip 8.1.1 on my ubuntu 16. But I am not able to install any modules via pip as I get this error all the time.

我的 ubuntu 16 上有最新版本的 pip 8.1.1。但我无法通过 pip 安装任何模块，因为我一直收到此错误。

File "/usr/local/bin/pip", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2927, in <module>

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'pip==7.1.0' distribution was not found and is required by the application

I had this issue for a very long time until I recently found that my 'pip' file (/usr/local/bin/pip) is trying to load the wrong version of pip. I believe you also have 8.1.1 correctly installed on your machine and can give following a try.

我有这个问题很长一段时间，直到我最近发现我的“pip”文件（/usr/local/bin/pip）试图加载错误版本的 pip。我相信您的机器上也正确安装了 8.1.1，可以尝试以下方法。

1. Open your /usr/local/bin/pip file. For me it looks like :

   __requires__ = 'pip==9.0.1'
   import sys
   from pkg_resources import load_entry_point
   if __name__ == '__main__':
       sys.exit(
           load_entry_point('pip==9.0.1', 'console_scripts', 'pip')()
   )
   

2. Change 'pip==9.0.1' in line 1 and last line to whichever version you have installed on your system, for example you will need to change 7.1.0 to 8.1.1.

1. 打开您的 /usr/local/bin/pip 文件。对我来说，它看起来像：

   __requires__ = 'pip==9.0.1'
   import sys
   from pkg_resources import load_entry_point
   if __name__ == '__main__':
       sys.exit(
           load_entry_point('pip==9.0.1', 'console_scripts', 'pip')()
   )
   

2. 将第 1 行和最后一行中的 'pip==9.0.1' 更改为您系统上安装的任何版本，例如您需要将 7.1.0 更改为 8.1.1。

Basically /usr/local/bin/pip is an entry file for loading the pip required version module. Somehow when I am upgrading/changing pip installation this file is not getting updated and so I update it manually every time.

基本上 /usr/local/bin/pip 是用于加载 pip 所需版本模块的入口文件。不知何故，当我升级/更改 pip 安装时，此文件没有更新，因此我每次都手动更新它。

I did not manage to get it to work by using easy_install pipor updating the pip configuration file /usr/local/bin/pip.

我没有设法通过使用easy_install pip或更新 pip 配置文件来使其工作/usr/local/bin/pip。

Instead, I removed pip and installed the distribution required by the conf file:

相反，我删除了 pip 并安装了 conf 文件所需的发行版：

Uninstalling pip:

卸载pip：

$ sudo apt purge python-pipor $ sudo yum remove python-pip

$ sudo apt purge python-pip或者 $ sudo yum remove python-pip

Reinstalling required distribution of pip (change the distribution accordingly):

重新安装所需的 pip 分发（相应地更改分发）：

$ sudo easy_install pip==9.0.3

$ sudo easy_install pip==9.0.3

Delete all of the pip/pip3 stuff under .local including the packages.

删除 .local 下的所有 pip/pip3 内容，包括包。

sudo apt-get purge python-pip python3-pip

Now remove all pip3 files from local

现在从本地删除所有 pip3 文件

sudo rm -rf /usr/local/bin/pip3

you can check which pip is installed other wise execute below one to remove all (No worries)

您可以检查安装了哪个 pip 其他明智地执行下面的一个以删除所有（不用担心）

sudo rm -rf /usr/local/bin/pip3.*

Using pip and/or pip3, reinstall needed Python packages.

使用 pip 和/或 pip3，重新安装所需的 Python 包。

sudo apt-get install python-pip python3-pip

After upgrading from 18.0 to 18.1, I got the same error. Reinstalling the program(without using pip itself) worked for me:

从 18.0 升级到 18.1 后，我遇到了同样的错误。重新安装程序（不使用 pip 本身）对我有用：

$ curl https://bootstrap.pypa.io/get-pip.py > get-pip.py
$ sudo python get-pip.py

if you have 2 versions of pip for example /usr/lib/pipand /usr/local/lib/pipbelongs to python 2.6 and 2.7. you can delete the /usr/lib/pipand make a link pip=>/usr/local/lib/pip.

例如/usr/lib/pip，如果您有 2 个版本的 pip并且/usr/local/lib/pip属于 python 2.6 和 2.7。您可以删除/usr/lib/pip并创建一个链接 pip=>/usr/local/lib/pip。

Just relink to resolve it. Find which python : ls -l /usr/local/bin/python

只需重新链接即可解决。找到哪个 python ：ls -l /usr/local/bin/python

ln -sf /usr/local/Cellar/python/2.7.12/Frameworks/Python.framework/Versions/2.7/bin/pip /usr/local/bin/pip

Or reinstall pip: https://pip.pypa.io/en/stable/installing/

或者重新安装pip：https: //pip.pypa.io/en/stable/installing/

A bit late but if easy_install doesn't solve the issue, this worked fine for me:

有点晚了，但如果 easy_install 不能解决问题，这对我来说很好用：

$ vim /usr/local/bin/pip

Then run:

然后运行：

:%s/7\.1\.0/8\.1\.1/g
