Question

我有python 2.7.5，我安装了一些软件包

python setup.py install --user

所以在

中安装了这个包

/users/me/.local/lib/python2.7/site-packages

然后我将PYTHONPATH变量更新为

/users/me/.local/lib/python2.7/site-packages,/users/me/.local/lib/python2.7/site-packages

但现在如果我尝试

virtualenv

这是我安装的软件包，我得到了

bash: virtualenv: command not found

如何使用已安装在site-packages之外的virtualenv包？

修改

这是我的sys.path

'', '/users/me/.local/lib/python2.7/site-packages/virtualenv-15.1.0.dev0-py2.7.egg', '/usr/lib/python2.7/site-packages/pip-7.1.2-py2.7.egg', '/usr/lib/python2.7/site-packages/supervisor-3.2.0-py2.7.egg', '/usr/lib64/python27.zip', '/usr/lib64/python2.7', '/usr/lib64/python2.7/plat-linux2', '/usr/lib64/python2.7/lib-tk', '/usr/lib64/python2.7/lib-old', '/usr/lib64/python2.7/lib-dynload', '/users/me/.local/lib/python2.7/site-packages', '/usr/lib64/python2.7/site-packages', '/usr/lib64/python2.7/site-packages/gtk-2.0', '/usr/lib/python2.7/site-packages', '/users/me/.local/lib/python2.7/site-packages'

但我仍然得到命令not found error

另外，这是我的$ PATH

/usr/lib64/qt-3.3/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/users/me/.local/lib/python2.7/site-packages:/users/me/.local/lib/python2.7/site-packages

您可以在PYTHONPATH环境变量中将路径的值附加到新库。

但您也可以在运行时追加路径。

import sys
sys.path.append('/dir1/dir2/libs')

python：不能使用在site-packages外部安装的软件包
