Python pip安装失败:无效的命令egg_info [英] Python pip install fails: invalid command egg_info

问题描述

最近我发现，当我尝试使用 Python 软件包时， href ="https://en.wikipedia.org/wiki/Pip_%28package_manager%29"> pip ，我收到以下错误.

I find that recently often when I try to install a Python package using pip, I get the error(s) below.

我在网上找到了一个参考，该参考必须使用下载目录中的" python2 setup.py install "，并且确实发现，如果我手动找到并下载该软件包(从pypi).

I found a reference online that one has to use "python2 setup.py install" from the download directory, and indeed find that this will then work if I manually find and download the package (from pypi).

但是，我不知道pip将软件包下载到哪里，和/或为什么这种方式失败.

But, I don't know where pip is downloading packages to, and/or why it is failing in this manner.

我尝试进行pip升级，但是它也以类似的方式失败，出现了一系列未知分发选项"错误(entry_points，zip_safe，test_suite，tests_require)！

I tried to do a pip upgrade, but it also failed in a similar manner, with a bunch of "Unknown distribution option" errors (entry_points, zip_safe, test_suite, tests_require)!

• 点1.0.1
• ActivePython 2.7

• pip 1.0.1
• ActivePython 2.7

尝试使用ActiveState的pypm失败，因为它们的库基较小，并且不包含这些软件包.

Trying to use ActiveState's pypm fails, because they have a smaller library base, and it doesn't include these packages.

推荐答案

安装应该像pip install Distribute一样简单.

Should be as simple as pip install Distribute.

Distribute从版本0.7开始已合并到Setuptools中.如果您使用的是< = 0.6版本，请使用pip install --upgrade setuptools或easy_install -U setuptools升级.

Distribute has been merged into Setuptools as of version 0.7. If you are using a version <=0.6, upgrade using pip install --upgrade setuptools or easy_install -U setuptools.
