python ubuntu virtualenv - >错误

Question

新手在这里,善待.

前几天我都是:

sudo apt-get install python-virtualenv

然后我(按照说明):

virtualenv env

而Ubuntu 10.10就像:

Traceback (most recent call last):
  File "/usr/local/bin/virtualenv", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 2675, in <module>
    parse_requirements(__requires__), Environment()
  File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 552, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: virtualenv==1.5.1

是什么赋予了？

Answer 1

升级到Ubuntu 11.04之后有同样的问题..

事实证明这只是因为安装了python-virtualenv 1.4,这太旧了.

我删除了deb包并使用了pip install,它工作正常.

pip install virtualenv

Answer 2

该python-virtualenv包应安装virtualenv在/usr/bin/.

相反,回溯错误消息表明您正在运行/usr/local/bin/virtualenv.也许卸载/usr/local版本virtualenv,然后再试一次.
