DistributionNotFound after pip install

When I run shadems --help, I get

Traceback (most recent call last):
  File "/usr/local/bin/shadems", line 4, in <module>
    __import__('pkg_resources').require('shadems==0.4.0')

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'shadems==0.4.0' distribution was not found and is required by the application

When I do, pip3 show shadems, I get WARNING: Package(s) not found: shadems but works fine for everything else that was installed with pip3 (like numpy or scipy). Clearly, something is wrong with the installation or the environment.

I am using Ubuntu 18.04 with python 3.6 and pip3 20.2.4. I followed the standard installation instruction from readme and installation went fine. The installation log is available here: log.

Am I missing something?

Yeah that's pretty weird, the install log looks just fine. Could you try two things to see if they make a difference:

• install into a virtualenv

• checkout the b050 branch and install that (it's a better branch to use anyway)

[sarrvesh]

Ah, my bad. The problem is in my installation script. I was deleting the cloned GitHub repo while cleaning up all the build directories. Apologies for the noise and thanks for suggesting the `b050' branch. Will try it out.

b050 is now on master -- going to make a 0.5.0 release shortly.
