Python Pythonpath模块安装 [英] Python Pythonpath Modules install

问题描述

我对在python中安装模块感到恼火，并且遇到了很多麻烦，因此找到一个好的解决方案将是很棒的.这是我的问题:

I am kind of annoyed by the installation of modules in python and had a lot of trouble with it, so it would be fantastic to find a good solution for it. Here are my issues:

1. PYTHONPATH:如何告诉easy_install/Python软件包安装位置?

即使我在.bash_profile

使用:

PYTHONPATH="/Library/Python/2.6/site-packages"
export PYTHONPATH

它不会导入我在那里的软件包.

It wont import packages I have there.

在另一个网站上，我输入的所有内容:

On the other site everything I put into:

/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages

工作.我不知道为什么，也很想知道.

Works. I dont know why and would love to know.

1. 我只是使用命令easy_install south安装"south"，然后猜中了它，将其安装到了:

1. I just install "south" with the command easy_install south and it installed it, guess, right into:

/Library/Python/2.6/site-packages

现在复制安装在此处的"south"(位于名为South-0.7.2-py2.6.egg的文件夹中，我只是向南复制)并将其粘贴到

Now copied "south" Which was installed there (it was in a Folder called: South-0.7.2-py2.6.egg, i just copied south) and pasted it to

/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages

现在我可以在进入django项目的目录(在其中我具有"south"的settings.py-Installed Apps)和

And now I can import it when going to directory of my django project (in which settings.py-Installed Apps I have 'south') and

python manage.py shell

根据南方的说法，这是行之有效的一个很好的指示.

Which according to south is a good indicator that it works.

1. 是否/必须为每个模块执行此操作?是否有更好的优雅方法来解决此问题.请说有.

谢谢

推荐答案

基于问题的路径(/Library/Frameworks/Python.framework/Versions/2.6)，您似乎还安装了除Apple提供的Python之外的其他Python.这是python.org OS X安装程序的标准安装路径.

Based on the path (/Library/Frameworks/Python.framework/Versions/2.6) in your question, you appear to have installed an additional Python besides the ones supplied by Apple. That's the standard installation path for the python.org OS X installer.

将easy_install安装到正确的Python站点软件包位置的技巧是了解您拥有的每个 Python实例的 own 副本. easy_install，并且您需要确保在安装软件包时使用的是正确的软件包.对于OS X 10.5和10.6，Apple在/usr/bin中为其提供的Python提供easy_install命令.例如，在10.6中:

The trick to getting easy_install to install to the right Python site-packages location is to understand that each Python instance you have needs to have its own copy of easy_install and you need to make sure you are using the right one when you install a package. For OS X 10.5 and 10.6, Apple supplies easy_install commands in /usr/bin for the Pythons it supplies. For example, in 10.6:

$ ls -l /usr/bin/easy_install*
-rwxr-xr-x  2 root  wheel  925 Jun 30  2009 /usr/bin/easy_install*
-rwxr-xr-x  1 root  wheel  421 Jun 30  2009 /usr/bin/easy_install-2.5*
-rwxr-xr-x  1 root  wheel  421 Jun 30  2009 /usr/bin/easy_install-2.6*

它们将安装到/Library/Python/2.x/中的适当位置，这是Apple提供的Python默认查找站点包的位置.

They will install into the appropriate locations in /Library/Python/2.x/ which is where the Apple-supplied Pythons look for site-packages by default.

对于python.org Python，默认站点包位置在/Library/Frameworks/Python.framework/Versions/x.y中.在适当的目录下，有一个您找到的lib/pythonx.y/site-packages和一个bin目录.要使Python成为默认位置，请确保bin目录位于您的Shell PATH上且位于/usr/bin/之前，所以类似:

For a python.org Python, the default site-package locations are in /Library/Frameworks/Python.framework/Versions/x.y. Under the appropriate directory there is a lib/pythonx.y/site-packages as you found and also a bin directory. To make the Python there the default, make sure that that bin directory is on your shell PATH and comes before /usr/bin/, so something like:

export PATH="/Library/Frameworks/Python.framework/Versions/2.6/bin:${PATH}"

默认情况下，python.org安装程序会尝试修改您的shell配置文件(如.bash_profile)来执行此操作.然后按照说明安装提供传统版本easy_install的 setuptools ，或分发，这是easy_install的最新版本.然后，您应该在框架bin目录中看到一个easy_install命令:

The python.org installers by default try to modify your shell profile files, like .bash_profile, to do this. Then follow the instructions to install either setuptools, which supplies the traditional version of easy_install, or Distribute, the more cutting-edge version of easy_install. You should then see aneasy_install command in the framework bin directory:

$ cd /Library/Frameworks/Python.framework/Versions/2.6
$ ls -l bin/easy_install*
-rwxr-xr-x  1 nad  admin  360 Aug 25 07:30 bin/easy_install*
-rwxr-xr-x  1 nad  admin  368 Aug 25 07:30 bin/easy_install-2.6*

，并且，如果您使用它来安装软件包，它们将最终安装在正确的位置，一切都会很愉快.

and, if you use it to install packages, they will end up in the right place and everything will be happy.
