Hi, I believe the output you see, even though it looks pretty error-y, is related to the not-so-important `install_egg_info` step that produces some Python metadata. AFAIK, this error output can be ignored and installation will continue. Do you have your full cmake and make install output? Perhaps there are other errors there?

Hi Mikael, Looks like you are missing one or more Python packages. Either "pytest" itself, or one of the extensions "pytest-xdist" or "pytest-timeout". It is suggested to use the Conda environment file, "environment.yml", which is included with the NEST source. It contains all Python packages you need to build, test, and work with NEST.

Learn why this is important <https://aka.ms/LearnAboutSenderIdentification> Hi, I have attached log files from cmake, make, make install and make installcheck. Yeah, it seems like I can ignore the install egg info since I can import nest after building. However the make installcheck fails. Any idea why? /Mikael Den ons 27 juli 2022 kl 11:41 skrev Robin Gilbert De Schepper < robingilbert.deschepper(a)unipv.it&gt;gt;: Hi, I believe the output you see, even though it looks pretty error-y, is related to the not-so-important `install_egg_info` step that produces some Python metadata.
