python - 使用 Pandas 时 dateutil.tz 包显然丢失了？

Question

我的python 2.7代码如下:

import pandas as pd
from pandas import DataFrame

DF_rando = DataFrame([1,2,3])

...然后当我执行时，我收到关于 dateutil.tz 的奇怪错误。

/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 /Users/mattobrien/pandas_test.py
No module named dateutil.tz
Traceback (most recent call last):
  File "/Users/mattobrien/pandas_test.py", line 2, in <module>
    import pandas as pd
  File "/Library/Python/2.7/site-packages/pandas/__init__.py", line 7, in <module>
    from . import hashtable, tslib, lib
  File "pandas/tslib.pyx", line 37, in init pandas.tslib (pandas/tslib.c:76999)
ImportError: No module named dateutil.tz

Process finished with exit code 1

很奇怪。我检查确实安装了 dateutil.tz。我卸载了 Pandas 并重新安装它以确保。没有问题。

为什么会出现此错误？

Answer 1

需要这两行。

sudo pip install python-dateutil --upgrade

sudo pip install pytz --upgrade
