In that thread, they are discussing removing the feature where pip install. I think you’re making the common mistake of confusing out-of-tree builds with build isolation. I’m not sure it is possible to somehow unify the editable and isolated build together, but for now it doesn’t happen, simply because editable does not build.Ĭurrent discussion to get rid of this “feature” is on It does not matter if one has the back-ends installed on per site or not, a PEP 517 front-end must acquire the front-ends every build (batch).

Build wheels from the source using install back-endsĪs you can see, it isolated the build back-ends from being installed to one’s working site.Build isolated install does the following:

On the other hand, wheel creates a portable achieve that is no longer dependent of the source tree (it can be deleted without any problem). Editable install links (either viia file system or via Python import magic that I don’t fully understand) your local source tree to your site, so that when you edit the local source, the installed version is updated as well. I’m not sure I understand what you mean by the other paragraphs though.

I’m not sure about other back-ends since editable is not really a well-defined standard (just look up on this discourse and you’ll see many loooong discussions on how to do it properly, but for the moment pip only thinly wraps around setup.py develop AFAIK).
Thanks, for the correction, said setup.py is needed for editable with flit as the back-end. There would be double the number of logs every time someone forgets to install wheel. It doesn’t install any packages as defined in a pyproject.toml. But right now the official recommendation seems to be to start using features of those PEPs as seen here: Īnyways the issue you linked seems to only change the message and not actually solve the problem. It would be a nice reassurance that I shouldn’t be using PEP 518/517. It’s very confusing and I have poured through the issues list trying to find a similar issue. I want to emphasize again that the concept of editable and build isolation does not goes together, at least for the moment, you can have one or the other but not both. The tweet explicitly states that setup.py is required even if setuptools is not the backend if you want editable installs to work. you need to add a shim setup.py to get pip install -e. If you don’t include a setup.py editable installs won’t work, but that is true for all backends, not just setuptools (e.g.
Edit: my memory is helpful this time, this is already fixed by GH-8180.

I want to emphasize again that the concept of editable and build isolation does not go together, at least for the moment, you can have one or the other but not both.Īs for the error, it’s probably pip's mishandling of error message, the more minimal sample is as simple as (recall that you don’t have wheel in a fresh venv): (foo) pip install six If user specify -use-pep517 on a project without the TOML file, the default will be used as described in PEP 518. PEP 517/518 is enforced (by pip AFAIK) if the project contains pyproject.toml.Editable needs setup.py is setuptools is the build backend.About the reference on Twitter, what they meant is probably (fix me if I’m wrong):
