我不得不将我的 npm 应用程序的版本从 0.1 更改为 0.0.1,以便 npm 不这样做。
$ npm install

为了完整起见,这里是工作 json
$ cat package.json
{
"name": "ply",
"description": "ply server for local dev testing deployments",
"version": "0.0.1",
"private": true,
"dependencies": {
"express": "3.x"
}
}
出错时的版本曾经是“0.1”。
这是某种需要 3 组版本号的 API/ABI 兼容性版本控制概念吗?为什么错误消息不是更友好w.r.t。这个?
最佳答案
是的,这是 semantic versioning 所必需的,这是 npm 包使用的版本控制方案。这里是 the snippet from npm help json
:
Version must be parseable by node-semver, which is bundled with npm as a dependency. (
npm install semver
to use it yourself.)Here's how npm's semver implementation deviates from what's on semver.org:
- Versions can start with "v"
- A numeric item separated from the main three-number version by a hyphen will be interpreted as a "build" number, and will increase the version. But, if the tag is not a number separated by a hyphen, then it's treated as a pre-release tag, and is less than the version without a tag. So,
0.1.2-7 > 0.1.2-7-beta > 0.1.2-6 > 0.1.2 > 0.1.2beta
