我一直在 Ubuntu 上使用 virtualenv,它很糟糕,所以我试图在我的 Mac 上使用它,但遇到了麻烦。
该virtualenv
命令成功创建了目录,并easy_install
很乐意在其中安装软件包,但我无法导入我安装的任何内容。似乎sys.path
没有正确设置:它不包括 virtual site-packages
,即使我使用该--no-site-packages
选项。难道我做错了什么?
我在 Mac OS 10.5.6 上使用 Python 2.5.1 和 virtualenv 1.3.3
编辑:这是我尝试使用 virtualenv 时发生的情况:
$ virtualenv test
New python executable in test/bin/python
Installing setuptools............done.
$ source test/bin/activate

编辑 2:使用activate_this.py
脚本有效,但运行source bin/activate
无效。希望这有助于缩小问题范围?
