Pip: Specifying minor version

In my requirements.txt file I want to specify that my app needs Django version 1.3.x. That is, either 1.3.0, or 1.3.1, or 1.3.2, etc. (When these come out.) But not 1.4, when it comes out.

What's 开发者_运维技巧the syntax for this?

According to Ian Bicking:

Django>=1.3,<1.4

However, it's apparently safer to do:

Django>=1.3,<1.3.99

my app needs Django version 1.3.x

In your case, use one of:

Compatible release

Django~=1.3.0

Ref: PEP 440 Compatible release

Version matching

Django==1.3.*

Ref: PEP 440 Version matching

Ordered comparison

Django>=1.3,<1.4

Note: ordered operators work for your case after the change introduced in this commit in 2015

Ref: PEP 440 Inclusive ordered comparison

Ref: PEP 440 Exclusive ordered comparison
