本地安装python包进行开发的最佳方法

像gpodder这样的程序可以直接从源代码签出处运行,这非常方便,但是其他程序希望“安装”运行。

许多程序都是用setup.py分发的,其中包含以root用户身份运行“python./setup.py install”的指令,这将把东西放在文件系统的某个地方。甚至还有像“develope”这样的install命令,它们似乎满足了我的需求。所以我试着:

export PYTHONPATH=/home/alex/python
python ./setup.py develop --install-dir=/home/alex/python

所以我尝试了以下方法:

 python /usr/share/pyshared/virtualenv.py /home/alex/src/goobook
 cd /home/alex/src/goobook/googbook.git
 /home/alex/src/goobook/bin/python ./setup.py develop

 cd /home/alex/src/goobook
 linkbin.pl bin/goobook

然而,调用抛出了一个额外的喋喋不休的负载,这似乎意味着它是错误的:
