用虚拟 Python 安装“Easy Install”和安装设置

Question

我试图在linux服务器上安装虚拟python，但我没有根访问权限。我已经阅读了自定义安装的PEAK开发手册，但是我仍然不知道我做错了什么。

以下是我的配置：

已创建.pythdisutils.cfg

 [install]
 install_lib  = /home2/me/lib
 install_scripts = /home2/me/bin

bashrc中的Python env路径：

 export  PYTHONPATH="${PYTHONPATH}:~/lib/"

虚拟python安装在：

 ~/lib/python2.4/site-packages
 ~/bin/python

我尝试了这些代码，但没有成功：

 sh setuptools-0.6c11-py2.4.egg
 sh setuptools-0.6c11-py2.4.egg --prefix=~
 ...

我得到的错误：

 TEST FAILED: /home2/me/lib/ does NOT support .pth files
 error: bad install directory or PYTHONPATH

 You are attempting to install a package to a directory that is not
 on PYTHONPATH and which Python does not read ".pth" files from.  The
 installation directory you specified (via --install-dir, --prefix, or
 the distutils default setting) was:

/home2/me/lib/

and your PYTHONPATH environment variable currently contains:

':~/lib/python2.4/site-packages/:~/lib/python2.4/site-packages/'

Here are some of your options for correcting the problem:

* You can choose a different installation directory, i.e., one that is
on PYTHONPATH or supports .pth files

* You can add the installation directory to the PYTHONPATH environment
variable.  (It must then also be on PYTHONPATH whenever you run
Python and want to use the package(s) you are installing.)

* You can set up the installation directory to support ".pth" files by
using one of the approaches described here:

Please make the appropriate changes for your system and try again.

Answer 1

您的PYTHONPATH设置似乎不正确。尝试“exec bash”，并验证

echo $PYTHONPATH

包含期望值。用$HOME替换~。

哦，你真的用bash作为外壳吗？除非重新启动shell并使用bash，否则修改.bashrc当然不会改变任何内容。

Answer 2

export PYTHONPATH="${PYTH/home2/me/lib"

看来。。。不是打字错就是错了。也许你的意思是。。。

export PYTHONPATH="$PYTHONPATH:/home2/me/lib"

是吗？
