无法安装Python包

Question

我对CentOS很陌生，我正在尝试在上面安装m2cypto Python包。

我跑了：

sudo python setup.py install

看起来一切正常：（这是输出的结尾）

removing 'build/bdist.linux-i686/egg' (and everything under it)
Processing M2Crypto-0.20.2-py2.4-linux-i686.egg
Removing /usr/lib/python2.4/site-packages/M2Crypto-0.20.2-py2.4-linux-i686.egg
Copying M2Crypto-0.20.2-py2.4-linux-i686.egg to /usr/lib/python2.4/site-packages
M2Crypto 0.20.2 is already the active version in easy-install.pth

Installed /usr/lib/python2.4/site-packages/M2Crypto-0.20.2-py2.4-linux-i686.egg
Processing dependencies for M2Crypto==0.20.2

但是我无法导入m2cypto：

$ python
Python 2.4.3 (#1, Nov 11 2010, 13:34:43) 
[GCC 4.1.2 20080704 (Red Hat 4.1.2-48)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import M2Crypto
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "M2Crypto/__init__.py", line 22, in ?
import __m2crypto
ImportError: No module named __m2crypto
>>> 

我做错什么了？

Answer 1

tests不是有效的目标，请运行test；这为我解决了问题。

Answer 2

我在centos 6.2上碰到了同样的问题。

运行测试也为我修复了它。不过，当我查看网站包时，没有任何变化。运行setup.py测试会在本地目录中生成m2crpyto。

这就是问题的关键，要在不运行setup.py test的情况下修复问题，请保留m2cypto文件夹。它从本地文件夹中提取m2crypto，却没有找到鸡蛋。

Answer 3

我跑了：

python setup.py tests

这就解决了问题。它复制了一些文件，我认为这导致了lib被放在正确的位置。

running test
running egg_info
writing M2Crypto.egg-info/PKG-INFO
writing top-level names to M2Crypto.egg-info/top_level.txt
writing dependency_links to M2Crypto.egg-info/dependency_links.txt
