Openpyxl missing 'jdcal'

Question

I tried to install the openpyxl module, but during the installation it showed some errors with JDcall. When I then try to import it, I get this error:

 Traceback (most recent call last):

ImportError: No module named 'jdcal'

I get this same problem for Python 3.4 and 3.3, how can I solve it?

Answer 1

You should install jdcal separately. After this, install Openpyxl. I faced the same issue - after doing this, it got resolved

Answer 2

jdcal is a library required by openpyxl but should be installed automatically. How are you installing openpyxl?

Answer 3

I managed to get openpyxl to work by uninstalling openpyxl, jdcall and et-xmlfile, then reinstalling all three, then upgrading all three.

Not sure why it works, and the error messages are still there, but I was able to successfully import openpyxl and create a workbook.

Answer 4

After I downloaded the jdcal-x.x.x.tar.gz from https://pypi.org/project/jdcal/#files and extracted it in \path\to\pythonxx\Lib\site-packages\ I had to copy the jdcal.py file from \path\to\pythonxx\Lib\site-packages\jdcal-1.4.1\ to \path\to\pythonxx\Lib\site-packages\ in order to work.
