Requirements.txt 大于等于然后小于？
Requirements.txt greater than equal to and then less than?
我的需求文件中有这一行
django>=1.10,<1.11
这是否意味着我需要 Django 版本 >= 1.10 然后低于 1.11？
是。 pip manual [doc] has a section on the format of "requirement specifiers". These are documented in PEP-508 [pep] and PEP-440 [pep]:
The comparison operator determines the kind of version clause:
~=: Compatible release clause==: Version matching clause!=: Version exclusion clause<=, >=: Inclusive ordered comparison clause<, >: Exclusive ordered comparison clause===: Arbitrary equality clause.
The comma (",") is equivalent to a logical and operator: a candidate version must match all given version clauses in order to match the specifier as a whole.
所以在你的情况下，这意味着 Django 版本是 1.10 或更高版本而不是 1.11 或更高版本（所以 1.10 很好，1.10.1，以及, 但不是 1.11、1.11.1 或 2.0.1).
