libedit @20190324-3.1: xattr fails: OSError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/pip-18.1.dist-info'

macOS 10.15 Xcode 11.1 Build version 11A1027

Trying to install libedit gives me

Error: Failed to patch libedit: command execution failed

Looking at the log file, I first found that the doc/Makefile.in patch was the culprit. Seems the patch was already applied in the dowloaded version

Removed that from the Portfile, but then it turned out many of the other patches couldn’t be applied either.

Pretty bad, since Python depends on libedit, and everything, it seems, depends on Python.

I am afraid I cannot reproduce this problem.
Please run:

• sudo port clean --all libedit
• sudo port install libedit

If the error persists, please attach the main.log file as requested in the resulting error message.

Thanks for looking into this.

Forget what I wrote about the patches already being applied, that must have been due to re-applying them on a half patched directory or something.

main.log is attached.

This page discusses trouble with permissions and macOS’ Python installation:

The recommendation is to install python using MacPorts. Catch 22.

Josh, the code that's failing here is the code you added in [a30928089b100fcb638a423f72afc5adee209924/macports-ports]. Any ideas?

[jmroot (Joshua Root)]

Looks like a broken /usr/bin/xattr due to this: ​https://github.com/pypa/setuptools/issues/617

You need to make sure all dist-info files in your python site-packages are readable.

[jmroot (Joshua Root)]

A new upstream version of libedit was released very recently, and it looks like the files no longer have the stray xattrs.

[mabartibin]

So the workaround was to make the pip-18.1.dist-info directory world readable.

That solved the problem, at least for now.

Thanks for your help!

In 360205c7847d3ca34bdf79640c5030918c708a50/macports-ports (master):

libedit: update version 20190324-3.1->20191025-3.1

Fixes #59477

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

The underlying problem with Python is not addressed, but xattr is no longer needed.
