"No such file or directory" install error when egg fragment / project name differs from package name

[xlqian]

• Pip version: 10.0.0
• Python version: 2.7
• Operating system: Ubuntu 16.10

Description:

"No such file or directory" when pip-installing with #egg=~

What I've run:

pip install git+https://github.com/clarkduvall/serpy.git@master#egg=TOTO

Errors I've got:

My Guess

It seems that pip will git-clone the project into a tmp dir /tmp/pip-install-lE7moQ/TOTO, but when running the installation, it will look for the setup.py in /tmp/pip-install-lE7moQ/serpy/, which was not produced in pip==9.0.1

[dgilland]

I'm having the same issue as @xlqian when using egg fragments in install URLs using pip@10.0.0. I also confirmed that there's a mismatch for the clone/build directory with the clone target being /tmp/pip-install-<id>/<#egg> but the build target being /tmp/pip-install-<id>/<packagename>.

• on OS Ubuntu 16.04LTS, within a conda environment conda 4.5.4
• pip 10.0.1 from /home/tom/anaconda3/envs/pcenv/lib/python3.5/site-packages/pip (python 3.5)

I think I am experiencing a similar/same problem, however with an #egg=~ clone link.

Trying to install version of IfcOpenShell.

pip install git+git://github.com/IfcOpenShell/IfcOpenShell.git@v0.5.0-preview2

Returns the following error:

FileNotFoundError: [Errno 2] No such file or directory: '/tmp/pip-req-build-m9n4zjp9/setup.py'

Edit: Not the same problem

@themmes
I have the same problem too.

I just tested this, and the complete is actually much more confusing than provided in the top post (the same from 10.0 to master):

Some initial observations:

• The installation actually succeeds in the end (!)
• There is a warning pinpointing the underlying cause: #egg= must match the project name in metadata
• The error seems to come from the setuptools shim
• Installed package uses the name specified in metadata, not #egg= (which is only used to name the source directory)

[uranusjr]

Also @francopythonss your error is caused by a different code path, and probably (I am not sure) should be reported as a separate issue. This issue is specific to installing from VCS with #egg=.

[uranusjr]

I did some debugging, here’s what I observed:

The package in question (serpy in this case) is actually installed twice. As mentioned previously, both are under the same name serpy.

The first installation correctly succeeds, but the second one generates the error because the source is deleted during the clean up phase of the first installation.

The second installation entry is added by the resolver. pip install generates a Requirement object from the argument passed to it, and adds it to a RequirementSet, which keeps Requirement objects as an OrderedDict (and other things not relevant here). This RequirementSet is passed to the resolver, which recursively discovers more dependencies, and adds more Requirement objects for those dependencies to the RequirementSet. The mismatching #egg= value, however, makes RequirementSet keep the initial Requirement under a wrong key (TOTO) during initialisation. So when the resolver processes the Requirement of serpy, it incorrectly thought it is not in the RequirementSet yet, and adds it again, this time under the correct key:

pip/src/pip/_internal/resolve.py

Lines 290 to 297 in 116c3b1

	# We add req_to_install before its dependencies, so that we
	# can refer to it when adding dependencies.
	if not requirement_set.has_requirement(req_to_install.name):
	# 'unnamed' requirements will get added here
	req_to_install.is_direct = True
	requirement_set.add_requirement(
	req_to_install, parent_req_name=None,
	)

Unfortunately, after knowing this, the fix is still not straightforward. For a remote, non-dist requirement, pip cannot know the package name before it downloads and runs setup.py (which is why #egg= is needed), but it cannot run setup.py before it knows what the package is. [*] So the #egg= specification (or the name before @ for the PEP 508 variant) really really must match the one in setup.py. So maybe the “fix” would be to hard-error when pip finds they don’t match, instead of showing a warning and failing later down the line.

[*]: Theoretically I believe it can, but that would probably require a huge restructure to implement.

[cjerdonek]

I don't know if hard-erroring is permissible or not (e.g. for backwards compatibility). However, as long as pip isn't hard erroring, what about fixing the RequirementSet key once pip notices it is wrong? It seems that has the potential of letting pip continue without doing more harm.

[uranusjr]

It is definitely possible. pip can already perform some name inference if you don’t provide the #egg= at all, in fact. This works correctly:

pip install git+https://github.com/clarkduvall/serpy.git@master

But I don’t know exactly when this would work and when not. The mismatching name causes inconsistencies within the data structure, and while this particular RequirementSet problem is relatively easy to plug, I don’t know if there are more inconsistencies that can pop up in the future (do anyone?), and what consequences they would cause. Personally I think it would make pip harder to maintain in the future.

Maybe a possible approach is to hard-error on mismatching egg name, and instruct the user to try removing it. This would mostly solve the problem if the egg name inference works most of the time (but again, I don’t know if it does).

[cjerdonek]

I don’t know if there are more inconsistencies that can pop up in the future

Yes, that is definitely possible. If a change to fix the key were done, one would definitely want to audit / review the code to make sure no code still has references to the old name (and possibly do some refactoring to make sure the name is always being accessed through a single code path).

Issue #5051 will help with making the installation code simpler to reason about (perhaps more functional), but that is a longer term project.

[saif-ellafi]

I was having this issue until I noticed I should have quoted the whole thing in command line

e.g.
pip install "git+https://github.com/clarkduvall/serpy.git@master#egg=TOTO"

[ncoghlan]

From the report and discussion in pypa/packaging-problems#252, it looks like projects switching over to PEP 517 from build_requires in setuptools may start encountering this bug, as one of the effects of that transition is that they go from installing their build dependencies with easy_install to installing them with pip, and the two installers behave differently in this regard.

[rbhanot-1mg]

This error drove me crazy since the name of the package was different in setup.py and the name mentioned in egg. It was not really practical for me to change all the egg names to match the name in setup.py. I upgraded my pip version to 9.0.3 and this fixed my issue.

[dHannasch]

This error can also be caused by a dependency specified in setup.py install_requires like 'sk-video @ git+https://github.com/scikit-video/scikit-video.git@master', which appears to be equivalent to to how you'd specify egg=sk-video when pip-installing on the command line.

With such a setup.py:

$ pip --version
pip 19.3.1

Fortunately, when installing directly from GitHub, you're not bound to use the same name that PyPI uses, so in this example you can just change it to 'scikit-video @ git+https://github.com/scikit-video/scikit-video.git@master'.

We'd probably want to look into this as apart of #6607.
