任何想法如何更新窗口框上的Python PIP？

pip install --upgrade pip不起作用，因为Windows FS被脑损坏，不会让你删除一个打开的文件。任何想法如何更新窗口框上的Python PIP？

我已经尽我的环境设置，我想更新，然后从不同的点子运行的virtualenv，但失败：

我希望其他人想出一个办法在这附近。它在Linux上没有问题....

我得到了错误，但升级确实起作用。 – yoyo 2015-07-08 05:25:48

很高兴看到3.5年之后，这仍然是一个问题，在Windows上使用最新的Python 2.7.10和pip 7.1.2。下面的建议没有解决它。太棒了。 – jarmod 2015-11-05 14:45:52

为我工作的解决方案是[here]（http://stackoverflow.com/a/17687817/2412846）。简而言之：您使用pip更新pip，但在运行时无法覆盖自身。将它复制到某处并从那里运行。 – davidhigh 2016-11-13 00:01:04

easy_install -U pip

太简单了。我不知道easy_install的确了解了virtualenvs。谢谢。 – boatcoder 2010-12-07 18:10:02

[更新2015年11月15日]这篇文章是过时和落伍。目前最好的做法是according to pip是使用以下命令：

python -m pip install -U pip setuptools

这是没有必要使用easy_install从setuptools。从pip-installer页面推荐更新点的步骤是使用get-pip.py。

要安装或升级PIP，安全地下载get-pip.py。

您可以在Bash shell如msysgit's Git Bash中使用以下内容。

[email protected] ~$ curl -L https://raw.githubusercontent.com/pypa/pip/master/contrib/get-pip.py | python

使用-L选项可遵循重定向。最近GitHub更改了原始内容的网址，因此the old raw get-pip.py url已被redirected和点子网站the url was changed。如果成功的话，你应该看到以下内容：

$ curl -L https://raw.githubusercontent.com/pypa/pip/master/contrib/get-pip.py | python 
    % Total % Received % Xferd Average Speed Time Time  Time Current 
           Dload Upload Total Spent Left Speed 
100 1309k 100 1309k 0  0 364k  0 0:00:03 0:00:03 --:--:-- 366k 
Downloading/unpacking pip from https://pypi.python.org/packages/py2.py3/p/pip/pip-1.5.6-py2.py3-none-any.whl#md5=4d4fb4b69df6731c7aeaadd6300bc1f2 
Installing collected packages: pip 
    Found existing installation: pip 1.5.4 
    Uninstalling pip: 
     Successfully uninstalled pip

Cleaning up...

您可以修改此为Windows命令行，但首先，如果你不具备的libcurl，download a Windows binary from Curl。您需要一直滚动到底部并获取Günter Knauf's current official Win32 binary (currently 7.29)并将其解压缩。不要担心它是32位还是64位。只要确保你获得了所有的钟声和口哨声（ssl，zlib等）。现在导航到您下载卷曲的文件夹，可能是c:\Users\<you>\Downloads，打开解压缩的文件夹，可能是curl-7.29.0-rtmp-ssh2-ssl-sspi-zlib-idn-static-bin-w32，您应该找到curl.exe。好极了！现在在一个Windows外壳程序中，在提示符（它将使用您的用户名而不是myusername）之后键入此内容，将path\to\Curl\替换为下载的curl.exe文件的路径。

C:\Users\myusername> path\to\Curl\curl.exe -kL https://bootstrap.pypa.io/get-pip.py | python

您需要-k选项允许卷曲而不证书访问安全GitHub的点子网站。另外，谢谢Piotr Dobrogost告诉我有关Windows管道的问题，|，这节省了保存文件的步骤。

如果您已经有最新版本的点子，你会得到以下信息：

$ curl https://bootstrap.pypa.io/get-pip.py | python 
    % Total % Received % Xferd Average Speed Time Time  Time Current 
           Dload Upload Total Spent Left Speed

Requirement already up-to-date: pip in c:\python27\lib\site-packages 
Cleaning up...

同样工作在virtualenvs就好了。

将pip作为脚本运行，使用python作为主要可执行文件。

python -m pip install -U pip
