Dateutil和Pytz缺少依赖项 - Python

Question

我试图运行代码进行投资组合优化,我在导入大熊猫时得到以下错误.

Traceback (most recent call last):
  File "/Users/***/Desktop/Markowitz-master/MarkowitzOpt.py", line 2, in <module>
    from pandas import Series, DataFrame
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pandas/__init__.py", line 18, in <module>
    raise ImportError("Missing required dependencies {0}".format(missing_dependencies))
ImportError: Missing required dependencies ['pytz', 'dateutil']

我使用pip freeze检查所有已安装的软件包,并安装了puts和dateutil.

任何见解将不胜感激!

Answer 1

dateutil可能会与python-dateutil混淆,请尝试以下操作:

pip install python-dateutil pytz --force-reinstall --upgrade
