This may be a naive question, since I'm not very familiar with
installing from source, but does "build" compile the C extensions or
is this something that happens during "install"? In the first case
you would be missing the compiled C-extension, leading to the
described import error.<br>

And the first error line (of many) is:

This is bad practice and might lead to downstream issues. In particular, you might encounter ImportErrors due to missing compiled C extensions.
We recommend that you try running your code from outside the source tree.
If you are outside the source tree then you have a setup.py file in an unexpected directory: /home/idoerg/Downloads/biopython-master</pre>

<div>Hi,</div>

</div>
<div>I'm trying to install biopython from source,
since release 1.79 does not work with the newest
Swissprot FT records. Looking at the source of
SwissProt/__init__.py in github this issue seems
to be fixed and hopefully release 1.80 this will
work again. <br>

<div>However, I am encountering the following
