Version range syntax across npm, Cargo, pip, Composer, Go modules, Maven, NuGet and Bundler
Эта статья ещё не доступна на языке «Русский»; показан оригинал.
The caret and tilde operators do not mean the same thing everywhere, Go modules have no ranges at all, and a bare version number is an inclusive minimum in NuGet but only a soft suggestion in Maven.

What it is
| Ecosystem | ^1.2.3 |
tilde form | 0.x behaviour |
|---|---|---|---|
npm (node-semver) |
>=1.2.3 <2.0.0 — "changes that do not modify the left-most non-zero element" |
~1.2.3 := >=1.2.3 <1.3.0; ~1.2 := >=1.2.0 <1.3.0; ~1 := >=1.0.0 <2.0.0 |
^0.2.3 := >=0.2.3 <0.3.0; ^0.0.3 := >=0.0.3 <0.0.4 |
| Cargo | same shape; caret is the default — "1.2.3" means exactly "^1.2.3" |
same as npm (~1.2 := >=1.2.0, <1.3.0) |
0.2.3 := >=0.2.3, <0.3.0; 0.0.3 := >=0.0.3, <0.0.4 |
| pip / PEP 440 | no caret operator exists | ~=2.2 := >=2.2, ==2.*; ~=1.4.5 := >=1.4.5, ==1.4.*; a single-component ~=1 is invalid |
no special case: ~=0.2 allows any 0.* from 0.2 up |
| Composer | ^1.2.3 := >=1.2.3 <2.0.0, described as sticking "closer to semantic versioning" |
~1.2 := >=1.2 <2.0.0 (npm's ~1.2 stops at 1.3); ~1.2.3 := >=1.2.3 <1.3.0 |
^0.3 := >=0.3.0 <0.4.0; ^0.0.3 := >=0.0.3 <0.0.4 |
| Go modules | not applicable — no range syntax | not applicable | Minimal Version Selection tracks "the highest required version of each module" and builds with exactly that one version |
| Maven | not applicable (interval notation instead) | [1.0,2.0) := >=1.0 <2.0; a bare 1.0 is a soft suggestion only |
Maven "picks the highest version ... that satisfies all the hard requirements" |
| NuGet | not applicable | [1.0,2.0), same shape as Maven; a bare 1.0 means "Minimum version, inclusive" |
resolves to the lowest version that satisfies the range, not the highest |
| Bundler / RubyGems | not applicable (~>, the pessimistic operator) |
~> 2.2 := >=2.2 <3.0; ~> 2.2.0 := >=2.2.0 <2.3.0 — the last given component is the one allowed to move |
not applicable |
Why it matters
npm, Cargo and Composer agree on caret ranges, including the conservative rule below 1.0.0 that locks the first non-zero component, but their tildes differ and pip has no caret at all, spelling a similar idea with ~=. Maven and NuGet share [low,high) interval notation, yet a bare version number means opposite things: NuGet treats it as an inclusive minimum (and picks the lowest version that satisfies it), Maven as a soft preference that yields to any other package's hard requirement. Go modules drop ranges entirely; Minimal Version Selection always resolves to one concrete version per module. Bundler's ~> acts like npm's caret or its tilde depending on how many components are written: ~> 2.2 allows any 2.x from 2.2, ~> 2.2.0 only 2.2.x.
How to apply
- For Go, write an exact minimum version and let MVS resolve it — there is no range to express.
- Re-derive a constraint from its intended compatibility guarantee when generating one manifest format from another, rather than copying the operator.
- Double-check 0.x constraints specifically; npm, Cargo and Composer all restrict
^0.x.ymore than a casual semver reading suggests, while PEP 440's~=0.2does not.
Pitfalls
- Assuming pip understands
^. - Assuming a bare Maven version pins that exact version.
- Assuming
~> 2.2.0and~> 2.2allow the same range in Bundler; the precision changes the upper bound.
