Python3:尝试在Ubuntu 16.04中升级pip3，但未更新 [英] Python3: Trying to upgrade pip3 in Ubuntu 16.04 but it doesn't update

问题描述

基本上是标题.我想升级pip，因为我已经无法使用python获取新软件包了.

Basically, the title. I want to upgrade pip because I cannot get new packages in python because it is obsolete.

当我尝试从Ubuntu终端运行pip3 install --upgrade pip时，会发生这种情况:

When I try to run pip3 install --upgrade pip from the Ubuntu terminal, this happens:

    Collecting pip
  Using cached pip-9.0.3-py2.py3-none-any.whl
Installing collected packages: pip
  Found existing installation: pip 9.0.1
    Uninstalling pip-9.0.1:
      Successfully uninstalled pip-9.0.1
  Rolling back uninstall of pip

You are using pip version 9.0.1, however version 9.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

我应该如何解决这个问题?我试图清除pip并重新安装，但无济于事.

How should I solve this problem? I tried to purge pip and reinstall it,but to no avail.

另外，也尝试了pip的升级命令，但似乎不起作用.

Also, tried the upgrade command with pip too, but it didn't seem to work.

推荐答案

• 尝试:

  • Try:

    sudo pip3 install --upgrade pip
    

  权限被拒绝"错误通常可以通过在命令中添加"sudo"来解决.

  "Permission denied" errors are usually solved by adding "sudo" to your commands.

  (sudo只是执行具有特权的给定命令的关键字)

  (sudo is just a keyword to execute a given command with privileges)

  • 如果收到找不到命令"，则应执行以下操作:

  在命令控制台中输入Python，它将告诉您所使用的Python版本.

  Type Python into your command console, it will tell you which version of Python you are using.

  C:/>python
  Python 3.6.4 (v3.6.4:d48eceb, Dec 19 2017, 06:04:45) [MSC v.1900 32 bit (Intel)] on win32
  

  如果您具有 Python 3.x ，则应使用 pip3 ；如果您具有 Python 2.x ，则应使用 pip .

  If you have Python 3.x you should use pip3, if you have Python 2.x you should use pip.

  如果您使用的是正确的pip，但仍然收到找不到命令"，则必须安装pip:

  If you are using the right pip but still get the "command not found" then you have to install pip:

  对于 Python2.x :

  sudo apt-get install python-pip
  

  对于 Python 3.x :

  sudo apt-get install python3-pip
