Hello
I'm in the process of updating our local Galaxy tools to use conda dependency resolution, and I've hit a snag with a tool that requires Python 2.7 along with the Python 2.7-compatible version of Biopython 1.65.
I'd assumed that if I explicitly used the following in the "requirements" section of the tool XML:
<requirement type="package" version="2.7">python</requirement> <requirement type="package" version="1.65">biopython</requirement>
that the biopython install would respect the specified Python version, and that the command execution environment would be based on Python 2.7.
But in practice it appears I'm getting Python3 as I'm seeing errors:
File "XXXXXXXX/galaxy-tools/tools/pal_finder/pal_filter.py", line 129 print "\n~~~~~~~~~~" ^ SyntaxError: Missing parentheses in call to 'print'
This is happening both when running the tool tests via the planemo tests, and also when I install the tool from a local toolshed instance.
Can anyone advise how to coerce the Python dependencies to be 2.7-compatible?
Thanks in advance for any help,
Best wishes
Peter
