KeyError when installing Qt 5.12.3 linux desktop

[samfrances]

I'm getting the following error, which just started happening today, on multiple machines and using the last 3 versions of aqtinstall.

$ aqt install -O ~/Qt 5.12.3 linux desktop
Traceback (most recent call last):
  File "/home/sam/tempenv/lib/python3.7/site-packages/importlib_metadata/__init__.py", line 170, in __getitem__
    return next(iter(self.select(name=name)))
StopIteration

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/sam/tempenv/bin/aqt", line 10, in <module>
    sys.exit(main())
  File "/home/sam/tempenv/lib/python3.7/site-packages/aqt/__init__.py", line 38, in main

    module_name = dist.entry_points[0].name
  File "/home/sam/tempenv/lib/python3.7/site-packages/importlib_metadata/__init__.py", line 172, in __getitem__
    raise KeyError(name)
KeyError: 0

Any help much appreciated.

Issue #222 is the same. Sorry for opening a dupe. I literally noticed this at about the same time (several hours ago), and I checked for open bugs, found none. Then I was researching it on and off for a couple hours before opening my issue. I didn't refresh the issues list during that time, so I missed the fact that your ticket appeared.

Anyway we're in the (proverbial) same boat.

I wrote a "hack-around" that you might find useful:

sudo sed -i "s/        module_name = dist.entry_points\[0\]\.name/        module_name = 'HACKED'/" /usr/local/lib/python3.6/dist-packages/aqt/installer.py

Although your path would be /home/sam/tempenv/lib/python3.7/site-packages/aqt/installer.py

I'm going to paste my other content here and close my duplicate issue.

Fatal uncaught exception "aqt/installer.py", line 362, in show_aqt_version. Related: python3.6/dist-packages/importlib_metadata

aqtinstall/aqt/installer.py

Line 362 in 2f17a7d

module_name = dist.entry_points[0].name

I'm not confident to say whether or not this is a bug in aqtinstall or not.

Other possibilities:

• something wrong with py 3.6 importlib_metadata
• something wrong with the packaging or dist-info or "entry_points.txt" that pip downloads

This started failing for me "out of nowhere." It was working in one CI job, then the next time I ran the same job (with no changes to my code or build scripts), this failure happened.

I have a way to replicate it using Docker (see below).

This is the error:

        KeyError: 0

Here is a docker file that will reproduce the failure:

FROM ubuntu:18.04

RUN apt-get update

RUN apt-get --assume-yes install  python3
RUN apt-get --assume-yes install  python3-pip

RUN pip3 install -Iv aqtinstall==1.1.2

RUN python3 -m aqt install --base  --outputdir /tmp/Qt 5.15.0 linux desktop --archives icu qtbase qtconnectivity qtdeclarative qtgraphicaleffects qtimageformats qtquickcontrols qtquickcontrols2 qtsvg qttools

Versioning clue?? If you simply replace this:

FROM ubuntu:18.04

With this:

FROM ubuntu:20.04

And re-run docker build, then you can see it succeeds on Ubuntu 20.

Possibly related: python/importlib_metadata#278

If I do this, then I can once again run aqt as before:

pip3 uninstall importlib_metadata
pip3 install -Iv importlib_metadata==3.5.0

The entry_points uncaught exception reappears if I use importlib_metadata==3.6.0 or importlib_metadata==3.7.0
