缺少 python bz2 模块

Question

我已经安装在我的主目录中。

 [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，但我缺少 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
    ...
    ...
    ...

Answer 1

可能当您从源代码构建 python 时，您没有 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，如果您错过了其中的一些，您可能不会在您的案例中获得对 bz2 等库的支持。

您应该获得预构建二进制文件以避免这种情况。 Ubuntu 12.04 打包 python 2.7.3 ，你的脚本需要的版本。

Answer 2

导入熊猫时，python 3.8.2 发生了这种情况： import pandas as pd

导致一条长错误消息结尾：“错误：ModuleNotFoundError：没有名为’_bz2’的模块”

通过执行以下 2 个 bash 命令解决了这个问题：

 sudo apt-get install libbz2-dev
sudo cp /usr/lib/python3.8/lib-dynload/_bz2.cpython-38-x86_64-linux-gnu.so  /usr/local/lib/python3.8/

然后它工作得很好。
