修复 Python 报错 ModuleNotFoundError: No module named 问题

部署 superset 时，系统为 Ubuntu 18.04，自带的版本比较旧，因此额外安装的 Python 3.9 版本。

起因

在执行导入操作时报错

  File "/home/superset/venv/lib/python3.9/site-packages/pandas/io/common.py", line 8, in <module>
    import bz2
  File "/usr/local/lib/python3.9/bz2.py", line 18, in <module>
    from _bz2 import BZ2Compressor, BZ2Decompressor
ModuleNotFoundError: No module named '_bz2'

完整报错如下：

$ superset db upgrade

解决

这是因为编译 Python 时，系统缺少相关的依赖，因为部分模块没有自动编译出来，需要补充依赖重新编译即可生成额外的模块。

sudo apt install libbz2-dev

然后重新编译即可

cd Python-3.9.16/
./configure --enable-optimizations
make
sudo make altinstall

然后检查编译结果，可以看到在重新编译后，可以看到模块 _bz2.cpython-39-x86_64-linux-gnu.so 存在。

sudo find /usr/ -name '*_bz2*'
/usr/lib/python3.6/lib-dynload/_bz2.cpython-36m-x86_64-linux-gnu.so
/usr/local/qcloud/python/lib/python3.7/test/test_bz2.py
/usr/local/qcloud/python/lib/python3.7/test/__pycache__/test_bz2.cpython-37.opt-1.pyc
