python 2.7，ubuntu 10.04中的virtualenv

Question

我已经在ubuntu 10.04中安装了python 2.7：

./configure
make
sudo make altinstall

Python正常工作：

~$ python2.7
Python 2.7 (r27:82500, Mar  6 2013, 15:39:19)
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>

但：

~$ virtualenv -p python2.7 ~/virtualenv/python27
Running virtualenv with interpreter /usr/local/bin/python2.7
Traceback (most recent call last):
  File "/usr/local/lib/python2.6/dist-packages/virtualenv.py", line 1378, in <module>
    """.decode("base64").decode("zlib")
LookupError: unknown encoding: zlib.

WTF？

Answer 1

您正在使用2.6 python的virtualenv：检查您的行：

Traceback (most recent call last):
  File "/usr/local/lib/python2.6/dist-packages/virtualenv.py"

您在python2.7中安装了virtualenv吗？ 如果同时拥有两者，通常将其命名为virtualenv2.7。
