According to the documentation, your syntax should work correctly. The documentation states that:
setuptools
and pkg_resources
use a common syntax for specifying a project's required dependencies. This syntax consists of a project's PyPI name, optionally followed by a comma-separated list of "extras" in square brackets, optionally followed by a comma-separated list of version specifiers. A version specifier is one of the operators <, >, <=, >=, == or !=, followed by a version identifier.
The documentation gives a simple example like this:
docutils >= 0.3
# comment lines and continuations are allowed in requirement strings
BazSpam ==1.1, ==1.2, ==1.3, ==1.4, ==1.5,
==1.6, ==1.7 # and so are line-end comments
To expand upon that, if you want your package to require a version of docutils
greater than version 0.3 but less than version 0.5, code like this would work:
docutils >= 0.3, <=0.5
Two additional notes.
- The documentation also states that redundant/overlapping dependency specifications will be combined internally, so
docutils >= 0.3, >=0.2
would be combined into docutils >= 0.3
.
- Also, be careful about specifying conflicting version numbers, which "is meaningless and may therefore produce bizarre results." For example, I don't know why you would, but don't use this:
docutils >= 0.3, <=0.2
since this is impossible.
