Dear Galaxy list, I do not know if it is the right place to ask my question. I would like to create a tool dependency package for numexpr (a python library). I tried to do it taking examples from different tool dependency packages from iuc for example. I added my repository to the testtoolshed but when I tried to install it. The directory lib/python of my tool is empty. My repository is : package_python_2_7_numexpr_2_6_2<https://testtoolshed.g2.bx.psu.edu/repository/browse_repository?id=23c1f7fed262740a> The big difference I see between the one from iuc and mine is the url: For example, for pybigwig, the URL is : https://pypi.python.org/packages/source/p/pyBigWig/pyBigWig-0.1.9.tar.gz For my library numexpr I could not find such a url so I put the one I thought would be the good one: https://pypi.python.org/packages/31/43/7777ab9535c416faabd1865453389260fdad0...
