$ pip-run setuptools -- -m pip install --no-index .
So, you're installing setuptools in your current environment. Then you're installing the current project with --no-index
. But the current project needs setuptools (and wheel) installed. Since pip 23.1 we don't use setup.py
install for legacy projects, we do a build using an isolated environment. It's that build (which is a subprocess) that needs setuptools and can't get it because of the --no-index
.
You can avoid this by using --no-build-isolation
, or you can make setuptools and wheel available (via --find-links
or similar) for the isolated enviornment creation.
I agree that the error reporting isn't ideal. PRs to improve this would, of course, be welcome.
When running
~/stable-diffusion-webui/venv/bin/pip install --no-cache-dir torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118
I am encountering the same error with the addition of

before
ERROR: Could not find a version that satisfies the requirement setuptools>=40.8.0 (from versions: none)
In addition, running
./venv/bin/pip install setuptools wheel
returns

Requirement already satisfied: wheel in ./venv/lib/python3.11/site-packages (0.40.0)
Arch, pip 23.1.2, and python 3.11.3.
@tilktilk5 pleas provide the full error, you've left out the important information to which package is causing this error.
pip 22.3.1 encountered this issue when installing imgviz 1.7.3 in offline mode, too. Using win-10 python 3.10.9.
Interestingly, python setup.py install
works fine.
Since pip 23.1 we don't use
setup.py
install for legacy projects, we do a build using an isolated environment. It's that build (which is a subprocess) that needs setuptools and can't get it because of the--no-index
.
That statement doesn't match with what's going on with the workaround. The only difference between the execution that fails and the one that succeeds is additionally supplying wheel.
I realize the usage of pip-run
is probably confusing things, so let me illustrate without it. First, create a venv.

My guess is that pip has some logic that falls back from isolated builds when both setuptools and wheel are present.
You can avoid this by using
--no-build-isolation
, or you can make setuptools and wheel available (via--find-links
or similar) for the isolated enviornment creation.
Indeed, uninstalling wheel and then running with --no-build-isolation
does provide an error message that hints that wheel isn't installed.

I acknowledge that I'm holding it wrong, but I'm a seasoned user in the packaging ecosystem and I'm struggling to understand how to hold it right.
Maybe it would help if pip were to emit which build technique it's using ("attempting isolated build (requires dependencies to be installable)..." and "attempting fallback non-isolated build (detected setuptools and wheel available)" and "not attempting fallback non-isolated build (one or more of setuptools and wheel unavailable)"), possibly also with reference to directions as to what that technique does and how to address common issues with that technique or to aid pip in using a preferable technique.
Note also that the "fix" for the pip-run issue was to add setuptools and wheel to the test environment. Perhaps a more robust fix would be to update the package under test to define a "pyproject.toml" instead of a setup.py.
You can avoid this by using
--no-build-isolation
, or you can make setuptools and wheel available (via--find-links
or similar) for the isolated enviornment creation.
This does not work. It's clear that pip does not need setuptools since installing wheel alone is sufficient. It's also not clear that it even needs wheel, since it can somehow manage "Building wheels for collected packages: wheel" without having an existential crisis. See here for more information. I don't think it's too much to ask that pip install my-dependency-free-package.tar.gz
should work without an index, cache or internet connection.
I don't think it's too much to ask that

It is.
Build time dependencies need to be pulled in from somewhere to be able to build the package.
This is not a build time dependency. This is a core functionality of a package manager. I can do npm install
, go install
, dnf install
, and before 23.1, pip install
for dependency free packages without requiring any additional files. pip should contain everything it needs to install a local package and the current behavior is a regression.

No, it is not.
pip install

You can still do that, as long as you have a built distribution file (i.e. a .whl
file). See https://pradyunsg.me/blog/2022/12/31/wheels-are-faster-pure-python/.

I am not familiar with Python's own packaging; I use Arch Linux packages whenever possible.
I have the Arch Linux package python-setuptools
, version 1:69.0.3-1 (setuptools 69.0.3) installed system-wide.
Regards!
The lit
package doesn't appear to have a binary for your platform on https://download.pytorch.org/whl/rocm5.4.2 (which you specified in --index-url
). So pip is trying to build it from source for you, and to do that it needs setuptools, which also appears not to be available on https://download.pytorch.org/whl/rocm5.4.2.
I suspect you are using the PyTorch index incorrectly - you should probably re-read their installation instructions, and maybe ask for help on their forums. Maybe you were meant to use --extra-index-url
rather than --index-url
?
I have the Arch Linux package python-setuptools, version 1:69.0.3-1 (setuptools 69.0.3) installed system-wide.
This won't help, as pip builds packages in an isolated build environment, and so needs to download and install the build backend (setuptools in this case) regardless of whether you have it available in your system environment.
Maybe you were meant to use
--extra-index-url
rather than--index-url
?
FYI, users should be aware --extra-index-url
is inherently insecure for anything other than mirrors of the index url, it is therefore not part of the PyTorch instructions.
Likely the user is using a Python version not supported by PyTorch for that specific local build type, as you say they should check with PyTorch what is supported (installation instructions, help community, etc.).

@dreirund @tilktilk5 I was able to solve the issue by going into the stable-diffusion-webui directory and running following commands:
source venv/bin/activate
pip install lit
deactivate
./webui.sh
In my case, the lit

parameter, it was able to get setuptools and thus when you try again, it would already be installed.

Yes, dependencies across two indexes is not well supported in the Python packaging ecosystem right now. With Pip the only secure way is to run it across two different install commands, one against each index.
My understanding is PEP 708 will help here, as one index will be able to specify getting a package from a different index, but I am not sure if there are some nuances that might cause issues in practise for this example, and supportting it by any package installer is currently blocked until PyPI implements this feature.
Description
In https://github.com/jaraco/pip-run/issues/73, I was investigating an issue surfaced by the removal of setuptools/wheel by default from virtualenv on Python 3.12. While troubleshooting, I added Setuptools as a dependency (https://github.com/jaraco/pip-run/commit/d6783eadb1fb3713793998763201b4c32d766c21), but the error persisted:
The test that's failing is simply building a legacy Setuptools project (
setup.py
, nopyproject.toml
). It's failing to find Setuptools presumably because the tests are passing--no-index
.This error is confusing in a couple of ways:
Expected behavior
Ideally, pip shouldn't try to install setuptools if it's installed and satisfied. If it needs wheel and/or setuptools to do the build but it doesn't have one, it should state as much ("installing implied {setuptools or wheel} for legacy build"), and then only attempt to install the missing package.
Separately, it's apparent that the subprocess boundary isn't a good indicator of which project might be responsible. Better would be for pip to indicate which builder was used and maybe which project might be responsible (maybe).
