无法使用pip安装virtualenv

Question

我首先安装了distribute，然后使用easy_install pip进行了安装，但是在运行时： sudo pip install virtualenv

我收到以下错误消息：

Traceback (most recent call last):
  File "/usr/bin/pip", line 8, in ? sys.exit(
  File "/usr/lib/python2.4/site-packages/distribute-0.6.49-py2.4.egg/pkg_resources.py", line 345, in load_entry_point

我不知道该怎么办才能正确安装virtualenv？

Answer 1

您似乎正在使用Python from __future__ import absolute_import尝试使用包含from __future__ import absolute_import （Python 2.5或更高版本）的Python版本创建virtualenv。

您可以这样指定要使用的Python：

virtualenv -p /usr/bin/python2.7
