pypi wheel helped.

Thanks for the report; this message from pip is kind of infamous because it's non-specific to various possible causes:

1. PyPI server unreachable due to firewall, rate-limiting, or other network issues
2. pip version too old
3. python version too old
4. mismatch between instnalled pip and python versions

You could try wading through the output with pip3 install -vvv miniwdl and see if there are better clues.

thanks for the suggestion. It was indeed a python version mismatch.

Alright. If it's not feasible to upgrade the system python 3.5.2, Miniconda is a good way to set up a completely separate python installation (and miniwdl has a conda package as well as PyPI)

I hate miniconda too much for some reason... Just installed apt-get install -y python3.6 and it worked. The only problem is miniwdl does not support sudo-less execution and it's quite a pain...

[mlin]

You should not need to sudo miniwdl so long as the invoking user has permission to control Docker (which to be clear, indirectly provides root-like powers, at least over the file system)

@mlin I see. I was not being very clear. I wanted to install a pipeline environment from scratch without sudo as a user, but in order to use miniwdl I would have to install docker first, which is non-trivial using a root-less user, hence the whole task becomes non-trivial using a rootless user.
