Tkcalendar 安装正确但仍然出现“找不到模块”错误

Question

I installed tkcalendar as normal through pip and all installed fine:

C:\Users\Pavel>python -m pip install tkcalendar
Collecting tkcalendar

Installing collected packages: babel, tkcalendar
Successfully installed babel-2.7.0 tkcalendar-1.5.1

Yet when I try to run my script I get an error that module not found:

 File "C:/Python_working/exercies/tkinter.py", line 7, in <module>
    from tkcalendar import Calendar, DateEntry

ModuleNotFoundError: No module named 'tkcalendar'

I tried restarting Spyder, tried re-installing with pip but I only get a message that package already installed.

Finally, I tried installing the package with conda but here I get the following error:

PackagesNotFoundError: The following packages are not available from current channels:

  - tkcalendar

Not sure what else to do to solve this issue.

Using Python 3.7 and Spyder 3.3.6.

Update: Running python from command prompt and then running import tkcalendar works fine.

I found this guide to working with virtual environments in Spyder on github, but it seems a bit over my head...

Okay-dokay... found the answer in this post .

Basically, the idea is that for packages that are not a part of normal Spyder/Anaconda installation you need to go to Tools -> PYTHONPATH and add a new folder for each and every module. Then restart Spyder and all works all right.
