Ubuntu16+Python2.7环境下matplotlib报错No module named finance求解

Hey there, I’ve run into this exact issue before—let’s get it sorted out quickly!

Why this happens #

Starting with matplotlib 2.0.0, the finance module was pulled out of the main matplotlib package and turned into a standalone library called mpl_finance. That’s why your import is failing even though you have matplotlib installed properly.

Step-by-step fix #

1. Install the standalone mpl_finance library
   Since you’re using Python 2.7, make sure to use pip2 (the Python 2 version of pip) for installation. First, if you don’t have pip2 set up on Ubuntu 16.04, run this to install it:

   sudo apt-get update && sudo apt-get install python-pip
   

   Then install mpl_finance:

   sudo pip2 install mpl_finance
   

2. Update your import statements
   In your Python script, replace any lines referencing matplotlib.finance with the new standalone library:
   Replace this:

   import matplotlib.finance as mpf
   # OR
   from matplotlib.finance import candlestick_ohlc
   

   With this:

   import mpl_finance as mpf
   # OR
   from mpl_finance import candlestick_ohlc
   

3. Verify the fix
   Open a Python 2.7 shell and test the import to confirm everything works:

   import mpl_finance
   print(mpl_finance.__version__)  # Should output a version number without errors
   

If you hit permission issues during installation, double-check you’re using sudo for system-wide installs, or use a virtual environment if you’d rather avoid modifying system-level packages.
