任何想法如何更新Windows框上的python PIP？

Question

pip install --upgrade pip 因为Windows FS被脑损坏而无法删除打开的文件,因此无效.

我已经尝试将我的环境设置为我想要更新的virtualenv,然后从另一个pip运行,但是失败了:

(jm) E:\python\jm>c:\Python26\Scripts\pip install --upgrade pip

我希望别人找到解决方法.在linux上没问题....

Answer 1

easy_install -U pip

:-)

Answer 2

使用python作为主要可执行文件,将pip作为脚本运行.

python -m pip install -U pip

Answer 3

[更新2015-11-15]此帖已过时且已过时.目前的最佳实践是根据pip使用以下内容:

python -m pip install -U pip setuptools

这是没有必要使用easy_install从setuptools的.从pip-installer页面更新pip的建议过程是使用get-pip.py.

要安装或升级 pip,请安全下载get-pip.py.

您可以在像msysgit的Git Bash这样的Bash shell中使用以下内容.

user@machine ~$ curl -L https://raw.githubusercontent.com/pypa/pip/master/contrib/get-pip.py | python

使用该-L选项可以遵循重定向.最近GitHub更改了原始内容的URL,因此旧的原始get-pip.pyURL已被重定向,并在pip网站上更改了url.如果成功,您应该看到以下内容:

$ curl -L https://raw.githubusercontent.com/pypa/pip/master/contrib/get-pip.py | python

您可以为Windows命令行修改此项,但首先如果您没有libcurl,请从Curl下载Windows二进制文件.你想要一直滚动到底部并获得GünterKnauf目前的官方Win32二进制文件(目前是7.29)并解压缩它.不要担心它是32位而不是64位.只要确保你得到一个所有的钟声和口哨(ssl,zlib等).现在导航到你下载curl的文件夹,可能c:\Users\<you>\Downloads,打开解压缩的文件夹,curl-7.29.0-rtmp-ssh2-ssl-sspi-zlib-idn-static-bin-w32你应该找到curl.exe.好极了!现在在一个Windows shell中,在提示符后输入它(将使用您的用户名代替myusername),替换path\to\Curl\为下载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允许curl访问没有证书的安全GitHub pip站点的选项.另外,感谢Piotr Dobrogost告诉我有关Windows管道的信息|,这可以节省保存文件的步骤.

如果您已经拥有最新版本的pip,您将收到以下消息:

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

也适用于virtualenvs.
