我昨天大部分时间都在寻找安装的明确答案pip(Python的包管理器).我找不到一个好的解决方案.

我该如何安装？

我安装了Python 3.x(除了Ubuntu上的Python 2.x)并慢慢开始配对我在Python 2.x中使用的模块.

所以我想知道,对于Python 2.x和Python 3.x,我应该采用什么方法让pip变得简单？

我正在尝试在OSX上设置virtualenvwrapper,我发现的所有指令和教程都告诉我向.profile添加一个源命令,指向virtualenvwrapper.sh.我检查了所有的python和site-packages目录,我找不到任何virtualenvwrapper.sh.这是我需要单独下载的吗？点不正确安装？

这是/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/virtualenvwrapper的内容:

hook_loader.py      hook_loader.pyc     project.py      project.pyc     user_scripts.py     user_scripts.pyc

如你所见,没有virtualenvwrapper.sh.它在哪里？

我已经开始使用我的Mac来安装Python软件包,就像我在工作时使用Windows PC一样; 但是在我的Mac上,我在写入日志文件或站点包时遇到了频繁的权限被拒绝错误.

因此我考虑过运行pip install <package>,sudo但考虑到我只是希望将其安装在我当前的用户帐户下,这是一个安全/可接受的sudo使用方法吗？

来自日志文件I/O错误的示例回溯:

使用最近的(1.5)版本pip,我在尝试更新多个包时遇到错误.例如,sudo pip install -U pytz导致失败的原因是:

Wheel installs require setuptools >= 0.8 for dist-info support.
pip's wheel support requires setuptools >= 0.8 for dist-info support.

我不明白这个消息(我有setuptools2.1)或者该怎么做.

此错误的日志中的异常信息:

我想用python3.5基本上发展,但是当我安装该模块的python3.5很多次,它总是failed.And的termimal告诉我,更高版本,当我升级它没有工作.

不记得我在哪里读到这个,但无论是在这里的某个地方,还是在我关注的教程的评论中,一个人说:

'永远不要使用sudo pip install; 你可以在不知情的情况下覆盖重要的东西.使用pip install --user代替!'

虽然我看到很多关于sudo pip安装的引用,所以这个人知道他们在谈论什么,我应该避免它,或者......？

编辑:固定!

只需要输入.cache目录

我已经试过virtualenvwrapper文档说明,我已经试过这家伙的说明,以及这些 ......我已经试过sudo pip uninstall virtualenv ,sudo pip uninstall virtualenvwrapper,sudo pip3 uninstall virtualenv,sudo pip3 uninstall virtualenvwrapper试图每个指令集之前.我看过像这样的其他SO帖子,但是sudo问题与我自己的不一样.通过这个,我的意思是我在制作virtualenv时不使用sudo,如果我尝试使用sudo pip安装包,它只会说我已经安装了包(在virtualenv之外).

我也尝试过 pip install --user virtualenv(wrapper)

这是我做的:
