unrecognized pytest option -n

[jihyunbak]

this is after doing conda env update -f environment.yml

(nsdsnwb) [jhbak@catscan nsds_lab_to_nwb]$ pytest --basetemp=tmp -sv -n 8 tests
ERROR: usage: pytest [options] [file_or_dir] [file_or_dir] [...]
pytest: error: unrecognized arguments: -n
  inifile: None
  rootdir: /pool0/clusterfs/bebb/users/jhbak/proj/nsds_lab_to_nwb

@JesseLivezey is the -n 8 part intended?

[jihyunbak]

but I was able to run the test after removing -n 8

That line should work if pytest-xdist is installed https://github.com/BouchardLab/nsds_lab_to_nwb/blob/dc5ab965e6d9f6623341cf95077c4089cbfa7ae7/environment.yml#L33

Can you check if it made it into your environment? It runs multiple tests in parallel, which will be nice for the tests that try and run the whole pipeline on multiple blocks. Removing it will just run them serially, which is also fine (just slower).

Aha, my bad - I was in my old, differently named environment nsdsnwb when the conda env update created a new, standard-named environment nsds_nwb. It works in the new env. Thanks @JesseLivezey !
