Python Pythonpath 模块安装

我对在 python 中安装模块感到有点恼火，并且遇到了很多麻烦，所以如果能找到一个好的解决方案那就太棒了。以下是我的问题：

PYTHONPATH：如何告诉 easy_install/Python 在哪里安装我的包？

即使我将： /Library/Python/2.6/site-packages 放在我的 .bash_profile 中

：

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

它不会导入我在那里的包。

在另一个网站上，我放入的所有内容：

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

有效。我不知道为什么，也很想知道。

我只是使用命令 easy_install South 安装“south”，猜猜，它安装到了：

/Library/Python/2.6/site-packages

现在复制了“south”它安装在那里（它位于一个名为：South-0.7.2-py2.6.egg的文件夹中，我刚刚复制了south）并将其粘贴到

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

现在我可以在转到我的 django 项目目录时导入它（其中 settings.py-Installed Apps 我有“south”）和

< 根据 South的

说法，这是一个很好的指标，表明它可以工作。

我可以/必须为每个模块都这样做吗？有没有更好优雅的方法来解决这个问题。请说有。

谢谢

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:

PYTHONPATH: How can I tell easy_install/Python where to install my packages?

Even though I put: /Library/Python/2.6/site-packages in my .bash_profile

With:

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

It wont import packages I have there.

On the other site everything I put into:

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

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

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

/Library/Python/2.6/site-packages

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

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

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

Can/Do I have to do that for every module? Is there a better elegant way to solve this. Please say there is.

Thanks

根据您问题中的路径 (/Library/Frameworks/Python.framework/Versions/2.6)，除了 Apple 提供的 Python 之外，您似乎还安装了额外的 Python。这是 python.org OS X 安装程序的标准安装路径。

让 easy_install 安装到正确的 Python 站点包位置的技巧是了解您拥有的每个 Python 实例都需要有其自己的 easy_install 的副本，并且您需要确保在安装软件包时使用正确的副本。对于 OS X 10.5 和 10.6，Apple 在 /usr/bin 中为其提供的 Python 提供了 easy_install 命令。例如，在 10.6 中：

$ 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。

对于 python.org Python，默认站点包位置位于 /Library/Frameworks/Python.framework/Versions/xy 中。在相应的目录下有一个 lib/pythonx.y/site-packages 正如您所发现的，还有一个 bin 目录。要使 Python 成为默认目录，请确保 bin 目录位于您的 shell PATH 上，并且位于 /usr/bin/ 之前，例如：

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

python.org默认情况下，安装程序会尝试修改您的 shell 配置文件（例如 .bash_profile）来执行此操作。然后按照说明安装 setuptools，它提供传统版本的 easy_install< /code> 或分发，easy_install.然后，您应该在框架 bin 目录中看到一个 easy_install 命令：

$ 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，它们最终会出现在正确的位置，一切都会很顺利。

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.

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*

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.

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}"

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*

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