Question

我尝试在下面安装python。但这没效果。这需要“错误：错误的安装目录或PYTHONPATH”。

What's the proper way to install pip, virtualenv, and distribute for Python?

制作目录

$ mkdir -p ~/.python

添加.bashrc

#Use local python
export PATH=$HOME/.python/bin:$PATH
export PYTHONPATH=$HOME/.python

创建一个文件〜/ .pydistutils.cfg

[install]
prefix=~/.python

获取安装脚本

$ cd ~/src
$ curl -O http://python-distribute.org/distribute_setup.py

执行和错误

$ python ./distribute_setup.py

Checking .pth file support in /home/sane/.python/lib/python2.6/site-packages//usr/bin/python -E -c pass
TEST FAILED: /home/sane/.python/lib/python2.6/site-packages/ 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:
/home/sane/.python/lib/python2.6/site-packages/
and your PYTHONPATH environment variable currently contains:
'/home/sane/.python'
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:
http://packages.python.org/distribute/easy_install.html#custom-installation-locations

Please make the appropriate changes for your system and try again.
Something went wrong during the installation.

Answer 1

通常我在virtualenv中安装了我的全局Python安装中的distributed / easy_install aka setuptools。从这一点开始，我可以使用

创建专用的虚拟化环境

virtualenv --no-site-packages name-of-environment

真的不知道为什么要在这里摆弄PYTHONPATH。

将/ path / to / name-of-environment / bin添加到$ PATH足以添加虚拟化 Python到您的$ PATH。你不需要任何其他东西。

Answer 2

我选择pythonbrew。我可以在我的主目录中使用多个Pythons。这是一个很棒的工作。

在用户本地混淆Python安装（virtualenv，pip，distribute）
