在主要的Python安装中导入模块时出错：从不存在的venv Python调用模块

Question

I am working in an IPython interpreter started from the terminal (MacOSX) with just an ipython + enter . When I try to import pandas , I get the following error:

/Users/myusername/Documents/somefolder/virtualenvironment/adam_py/lib/python2.7/site-packages/pandas/__init__.py in <module>()
  4 
  5 try:
  ----> 6     from . import hashtable, tslib, lib
  7 except Exception:  # pragma: no cover
  8     import sys

/Users/myusername/tslib.pyx in init pandas.tslib (pandas/tslib.c:64182)()

ImportError: No module named compat

The first line of that error suggests that python is looking for pandas in a venv in a folder I deleted some time ago. I get a similar error when I try to import geopandas.

My Python installation is a homebrewed one. When I run which python in the terminal, I get this:

/usr/local/bin/python

I have been installing libraries with pip install a_library

What should I do?

Answer 1

I just deleted the folder containing the former virtual environment, closed the interpreter, pip-uninstalled pandas, pip-installed it again, and reopened the interpreter. Now I can import pandas without problems.
