주제: dependencies dialects package-managers semver

적용 대상: npm (node-semver ranges) · Cargo >= 1.0 · pip / PEP 440 · Composer >= 1.0 · Go modules (go.mod) · Maven · NuGet >= 4.3.0 · Bundler / RubyGems

증상: npm install resolves a version outside what a ^ range looked like it should allow · cargo update picks a version the constraint did not seem to permit · pip install 'package~=2.2' rejects a version the developer expected to match · Maven build resolves a lower version than a bare version number that looked like a strict minimum · bundle update jumps from 2.2 to 2.9 despite a ~> 2.2 constraint

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.y more than a casual semver reading suggests, while PEP 440's ~=0.2 does not.

Pitfalls

  • Assuming pip understands ^.
  • Assuming a bare Maven version pins that exact version.
  • Assuming ~> 2.2.0 and ~> 2.2 allow the same range in Bundler; the precision changes the upper bound.
