所以我打开一个终端,cd到我的桌面,然后运行:
virtualenv test_env
然后,我在正常环境中创建以下文件:
/home/jesse/.local/lib/python2.6/site-packages/foo_package/__init__.py
该文件包含一行:
print "importing from normal env"
在test_env中我创建:
/home/jesse/Desktop/test_env/lib/python2.6/site-packages/foo_package/__init__.py
含:
print "importing from test env"
现在我打开一个终端并运行:
$ /home/jesse/Desktop/test_env/bin/python
然后做:
>>> import foo_package
哪个输出:
importing from normal env
为什么不从test_env导入文件？我认为这是virtualenv的重点.我在这里错过了什么吗？
编辑: Jon H告诉我,我需要激活环境.但这似乎没有解决问题......

编辑3: 我发现了这个:https: //bugs.launchpad.net/ubuntu/+source/python-virtualenv/+bug/339904 显然,virtualenv + python 2.6 + ubuntu 9.04存在一些问题.不确定这是否与我的问题有关...我尝试通过Synaptic卸载python-virtualenv包,然后通过easy_install安装版本1.3.4的virtualenv,但仍然有同样的问题...

这看起来是一个进步,因为test_env东西出现在路径中,但它仍然无法正常工作.我认为我目前的问题是'/home/jesse/.local/lib/python2.6/site-packages'出现在'/home/jesse/Desktop/test_env/lib/python2.6/site-packages之前的路径中"
编辑4: Roger建议使用--no-site-packages选项创建env.我试过了.同样的问题.

同样,看起来问题是我的".local"中的网站包在路径中出现的位置早于"test_env"中的网站包.
