缺少python bz2 modu

Question

我已经安装在我的主目录。

[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Python2.7.x版本的脚本，结果发现缺少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

我试过安装bz2模块，但是我犯了很多错误

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

Answer 1

可能在您从源代码构建python时，没有bz2头。

在Ubuntu/Debian上安装它们：

sudo apt-get install libbz2-dev

软呢帽：

sudo yum install bzip2-devel 

重新构建python。 您可能会注意到，python在配置/构建时会检查许多库，如果您遗漏了其中的一些库，那么在您的案例中很可能无法获得对bz2这样的lib的支持。

您应该获得预构建的二进制文件来避免这种情况。Ubuntu 12.04包python 2.7.3，你的脚本需要的版本。

Answer 2

在CentOS 7上，安装bzip2 devel：

sudo yum install  bzip2-devel

然后重新编译python。

Answer 3

如果python安装在特定的位置，那么只安装libbz2-dev是行不通的。

centos有一个解决方案：

• Centos 6号

  sudo cp /usr/lib64/python2.6/lib-dynload/bz2.so /python_install_path/lib/python2.7
  

• 半人马座7

  sudo cp /usr/lib64/python2.7/lib-dynload/bz2.so /python_install_path/lib/python2.7
  

python_install_path通常是/usr/local/lib/python2.7/，如果您有自定义的python路径，则需要替换它。
