缺少python bz2模块

Question

我已安装在主目录中。

[spatel@~ dev1]$ /home/spatel/python-2.7.3/bin/python -V
Python 2.7.3

我正在尝试运行一个需要python 2.7.x版本的脚本，而我却丢失了bz2错误

[spatel@~ dev1]$ ./import_logs.py
Traceback (most recent call last):
  File "./import_logs.py", line 13, in <module>
    import bz2
ImportError: No module named bz2

我尝试安装bz2模块，但出现很多错误

 [spatel@dev1 python-bz2-1.1]$ /home/spatel/python-2.7.3/bin/python setup.py install
    ...
    ...
    ...

可能是从源代码构建python时，没有bz2标头。

在Ubuntu / Debian上安装它们：

sudo apt-get install libbz2-dev

软呢帽：

sudo yum install bzip2-devel

并再次构建python。您可能会注意到python在配置/构建时会检查很多库，如果您错过其中的一些库，那么您的案例可能就不会支持bz2之类的库。

您应该获取预构建二进制文件，以避免此类情况。Ubuntu 12.04包含python
2.7.3
，这是脚本所需的版本。
