Python packages and PYTHONDONTWRITEBYTECODE

[Mansour Moufid <mansourmoufid%gmail.com@localhost>]

Hello again,

Just for reference, in case anyone else experiences this.

I was wondering why Python modules were failing to install, with errors about missing .pyc files like this:

pkg_create: can't stat `/Users/dev/usr/pkgsrc/textproc/py-libxml2/work/.destdir/Users/dev/pkg/lib/python3.12/site-packages/__pycache__/drv_libxml2.cpython-312.pyc'

But there were no .pyc files in work/.destdir or in PLIST...

It turns out I had PYTHONDONTWRITEBYTECODE=1 in my ~/.profile, because I don't like .pyc files. But pkgsrc expects these files.

So I added this line to usr/pkgsrc/lang/python/extension.mk before do-install:

INSTALL_ENV+=       PYTHONDONTWRITEBYTECODE=0

Now I can have PYTHONDONTWRITEBYTECODE=1 in ~/.profile and also keep pkgsrc happy.
