Pip: Specifying minor version

Question

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 the syntax for this?

Rest

Answer 1

According to Ian Bicking:

Django>=1.3,<1.4

However, it's apparently safer to do:

Django>=1.3,<1.3.99

Maybe it's obvious, but beware that if you want to automatically upgrade Django when a new version comes out on PyPI, you should call pip with the --upgrade flag, like this: pip install --upgrade -r requirements.txt – Neology

What happens if you (hypothetically) had Django v1.3.100 or later? – Usage

You can use ~=1.3.0 to get the latest patch version, see nok.github.io/pipdev?spec=~=1.3.0&vers=1.3.9999 . – Yves

Answer 2

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
