无法在虚拟环境中升级PIP

-1

我正尝试在虚拟环境中升级pip。我在ubuntu 14.04机器上使用了venvburrito wrapper。当我尝试更新它，我得到以下错误：无法在虚拟环境中升级PIP

(virtual_env) [email protected]:~$ pip install pip --upgrade 
Collecting pip 
    Using cached pip-9.0.1-py2.py3-none-any.whl 
Installing collected packages: pip 
    Found existing installation: pip 8.1.2

Successfully installed pip-8.1.2 
You are using pip version 8.1.2, however version 9.0.1 is available. 
You should consider upgrading via the 'pip install --upgrade pip' command.

如果我使用sudo尝试，在虚拟环境中，我得到以下错误：

当我做到这一点以外虚拟环境，它安装正确。

任何帮助将不胜感激。

如果你不完全知道你在做什么，请不要使用'sudo pip'！ 'sudo'不保留环境变量，所以它会“爆发”venv，并且可以改变系统python安装干扰本地安装的软件包。特别是如果你使用venvs，你永远不需要用sudo运行pip。 – mata

谢谢@mata，将注意到 – Escachator

@SiddheshMatre不错的工作，但你需要解释它是如何工作的kido，该点不能自行安装。 – 2017-03-01 11:41:49

有时这会有所帮助（我有类似的问题，PIP不升级，并且第一个命令工作对我来说）：

python -m ensurepip

或

python -m ensurepip --upgrade

听起来很有趣@Drako，但我得到'没有模块命名ensurepip'... – Escachator

我不知道，因为它是什么版本，但它肯定包含在3.6 – Drako

版本3.6的什么？谢谢 – Escachator

在虚拟环境中升级pip被只是一个PyPI package像任何其他;你可以用它来升级自己，你会升级任何包以同样的方式：

pip install --upgrade pip

在Windows和更安全的方法是run pip though a python module是：

python -m pip install --upgrade pip

python -m pip install -U pip

在windows似乎有一个二进制代码试图替换自己的问题，这种方法可以解决这个限制。

我不确定你是否阅读我的问题。这正是没有用的。 – Escachator

尝试一下然后决定。你不能使用'pip install pip --upgrade'来升级pip，这是不可能的，你必须做python -m pip install --upgrade pip。 –

@SiddheshMatre很好的工作，但你需要解释所有的小鬼，该点不能自己安装。 – 2017-03-01 11:34:36
