Editable installation isn't working properly

If pyperformance is installed as editable pip install -e . from the git repository, it doesn't work when invoked

$ /tmp/tmpdir/prefix/bin/python3 -u -m pyperformance                                        
ERROR: pyperformance should not be run without installing first                                                                         
(consider using the dev.py script)             

The check is done by is_installed() which calls both _is_dev() and _is_devel_install() which are both broken.

The function is_dev() bases the logic on the presence of setup.py which is long gone.

The function _is_devel_install() instead check the presence of pyperformance.egg-link in the site-packages.

In my installation I have:

• pyperformance.egg-info directory in the git repository
• __editable___pyperformance_1_0_9_finder.py, __editable__.pyperformance-1.0.9.pth, pyperformance-1.0.9.dist-info in the site-packages

I'm trying to invoke pyperformance using a dev instance via

python3.12 /work/oss/repos/pyperformance/dev.py compile_all benchmark.conf

and it will fail eventually:

pyperformance/init.py から始め、特に is_installed()、is_dev()、_is_devel_install() を確認し、その後 dev.py が editable installation をどのように作成して呼び出すかを調べます。pip install -e . と python -m pyperformance で失敗を再現します。editable installation がインストールチェックに合格し、dev.py のコンパイルフローから pyperformance を正常に呼び出せれば完了です。
