pandas: Problem with lzma module

I was getting this warning: /Users/usr/.pyenv/versions/3.9.5/lib/python3.9/site-packages/pandas/compat/__init__.py:97: UserWarning: Could not import the lzma module. Your installed Python is incomplete. Attempting to use lzma compression will result in a RuntimeError.

I was finally able to get rid of it with this command: CPPFLAGS="-I$(brew --prefix xz)/include" pyenv install [your version]

Just thought I’d drop this here for anyone with my same problem.

OS: Big Sur M1 chip pyenv python 3.9.5

When you’re getting above warning and building Python from source, make sure to

• Include required packages. Here, install the lzma module sudo apt-get install liblzma-dev
• Rebuild from source directory configure && make and sudo make install

These steps removed the warning for my Python 3.7.3. See also this Stack Overflow question

@corbinday’s solution worked for me.

OS: Monterey M1 chip pyenv python 3.9.7

I had this problem recently … but here, upgrading from Python 3.7.3 to Python 3.7.4 solved the problem!
