Hi All,
I have a job running on Jenkins server, which builds python script. The script
has to display a bar chart as final output.
The build agent I am using on Jenkins appears to have python installed. I
confirmed this by adding a build step as python3 —version and the result was:
Python 3.6.8.
Why then do I have this error showing. Do I need to install a plugin?
Kind regards
Mari
