Re: [Jython-users] How to install pillow

[Jeff M. <jef...@za...>]

fwiw, with xlsxwriter, I just imported that and good to go.

https://xlsxwriter.readthedocs.io/

I don't even bother with pip in this one project, I have a 'contrib'
directory that I drop in various libs. (Connectivity to internet is
unavailable on this target server, and working on cached egg files or
whatever seemed like work.) So in this case, I clone the repo to a dir in
contrib, use sys.path.append ( contrib-dir-path ), and then import
xlsxwriter
