常见问题

numpy: Something is wrong with the numpy installation.

python3 gasprice.py
Traceback (most recent call last):
  File "gasprice.py", line 4, in <module>
    import pandas as pd
  File "/home/surou/.local/lib/python3.6/site-packages/pandas/__init__.py", line 17, in <module>
    "Unable to import required dependencies:\n" + "\n".join(missing_dependencies)
ImportError: Unable to import required dependencies:
numpy: Something is wrong with the numpy installation. While importing we detected an older version of numpy in ['/home/surou/.local/lib/python3.6/site-packages/numpy']. One method of fixing this is to repeatedly uninstall numpy until none is found, then reinstall this version.

解决方法

rm -rf ~/.local/lib/python3.6/site-packages/numpy
pip install numpy

No module named 'click'

ModuleNotFoundError: No module named 'click'
