Buildout fails with 'ValueError: ('No requirements found', '')'

[tisto]

It seems like this line works only for more recent zc.buildout/zc.recipe.egg versions:

eggs = self.egg.working_set(extra=self.extensions)[1]

My configuration:

• zc.buildout 1.7.1
• zc.recipe.egg 1.3.2
• plone.recipe.codeanalysis 2.0a2

Trace (after running bin/buildout):

While:
  Installing code-analysis.

An internal error occurred due to a bug in either zc.buildout or in a
recipe being used:

Found the problem. I was using "flake8-extensions" instead of "flake8-extension". @saily can we amend the recipe to use "flake8-extensions"?

[tisto]

Ok. I was wrong. flake8-extension just works because it is ignored. Will fix the README.

[saily]

@tisto anything to do here?

[tisto]

@saily why did you close that issue? This is still a real regression.

[saily]

ok, sorry, thought you were wrong and i could close it. should we add a requirement to zc.bulidout>=2.0 or try to get it work in 1.7?
