Debugging bad constraint in buildout
Often to see bad constraint error during buildout when different packages are
depending on the same package with different versions. For example,
Error: Bad constraint 3.0.14 plone.protect>=3.0.19. Go to the folder where
all the downloaded eggs are stored, for example,
cd ~/.buildout-cache/eggs. Then use
find .|grep requires.txt|xargs grep 3.0.19 in command line for finding which
packages are depending on what package with this 3.0.19. More info
refer to
how do you know which python egg is enforcing a constraint in buildout?.
