如何处理错误消息-缺少必需的依赖项['numpy']-使用pycharm和anacoda

Question

I'm learning python and want this code to work.

import pandas

df =pandas.DataFrame([[2,4,6],[10,20,30]])
print(df)

This is what I get:

File "C:\Users\User\Anaconda3\lib\site-packages\pandas\__init__.py", line 19, in <module>
    "Missing required dependencies {0}".format(missing_dependencies))
ImportError: Missing required dependencies ['numpy']

I'm using pycharm with anaconda environment. Hopefully I've set the environment and interpreter up right. It says I have numpy version 1.16.2 installed, however it won't let me upgrade to version 1.17.0

Tried installing, uninstalling and upgrading through packages and terminal and upgraded pip. This is what I get:

Installing collected packages: numpy
  Found existing installation: numpy 1.16.4
    Uninstalling numpy-1.16.4:
      Successfully uninstalled numpy-1.16.4

WARNING: You are using pip version 19.1.1, however version 19.2.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

I'm very new to all this and probably doing something wrong, someone please help.

I would advise you to try and use the Anaconda GUI Navigator, available through the standard download of Anaconda Software Bundle.

You can easily manipulate virtual environments and install/uninstall different packages, using the self-explanatory GUI. I found it very simple and a good way to start using Anaconda and Python:
