error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

    [Errno 13] Permission denied: '/usr/lib/python3.8/site-packages/test-easy-install-327599.write-test'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /usr/lib/python3.8/site-packages/

Perhaps your account does not have write access to this directory?  If the
installation directory is a system-owned directory, you may need to sign in
as the administrator or "root" account.  If you do not have administrative
access to this machine, you may wish to choose a different installation
directory, preferably one that is listed in your PYTHONPATH environment
variable.

For information on other options, you may wish to consult the
documentation at:

  https://setuptools.readthedocs.io/en/latest/easy_install.html

Please make the appropriate changes for your system and try again.

I think the line

meson.add_install_script('setup.py', 'install', '--prefix', get_option('prefix'))

in my meson.build script should respect DESTDIR environment variable.

[hongquan]

I'm looking for a way to read environment variable from Meson script, which is not directly supported by Meson.

@yochananmarqos Please help test the 37a1a01d commit.

[yochananmarqos]

No difference, I'm afraid.

[hongquan]

@yochananmarqos Please send me the debug log (I don't use Arch, I cannot debug myself).

[hongquan]

Found the reason. When your tool run

DESTDIR="$pkgdir" meson install -C build

Meson just invoke Ninja to run the Ninja script generated previously. When the Ninja script was generated, the DESTDIR was not set, the the Ninja script didn't build the "python setup.py" command as we expected.

I'm looking for other solution.

@yochananmarqos This commit a54f71683fcf6403962923f95601cd676a03788e may fix it. Please help test.

That did the trick! 👍️
