node.js – 添加alpha后缀的npm版本

2023年6月5日 795次阅读

如何使用npm版本控制将package.json版本包含在-alpha中.

运行npm版本 将碰撞package.js文件的版本,但我想将-alpha postfix添加到版本,但我无法,因为它没有在文档中说明,但它由semver本身支持.

实际结果：

> npm version prerelease
> v0.2.1-1

预期结果：

> v0.2.1-alpha

最佳答案 虽然-alpha和-beta是常见的预发布标记,但它们不是由SemVer定义的. -alpha.1,-alpha.2,-beta.1等也很常见.规范将预发布标记定义为一系列点分隔的字母数字或数字字符字段. SemVer规范在某些示例中使用了alpha和beta,但它们并未由规范定义.如果你不告诉它,NPM无法知道你想要使用什么标签.它显然默认为数字预发布标记,这是有道理的,因为SemVer允许(-1,-2,-3提供所有必要的语义).

NPM文件很糟糕,幸运的是我从未使用过NPM.见https://docs.npmjs.com/cli/version.特别是：

The newversion argument should be a valid semver string, a valid second argument to 07001 (one of patch, minor, major, prepatch, preminor, premajor, prerelease), or from-git.

查看提供的链接(https://github.com/npm/node-semver#functions),它们似乎指的是增加指定的版本字段.如果package.json文件中的版本字符串上没有alpha标记,那么将缺少的数字预发布标记附加为-1会很有意义.

我刚刚测试了这个理论：

> echo Test > test.txt
> npm init
This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sane defaults.

See `npm help json` for definitive documentation on these fields
and exactly what they do.

Use `npm install <pkg> --save` afterwards to install a package and
save it as a dependency in the package.json file.

Press ^C at any time to quit.

About to write to D:\TMP\Joseph\packageTest\package.json:

  "version": "0.1.0-alpha.0",

  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },

}


Is this ok? (yes)

> npm version prerelease
v0.1.0-alpha.1

> cat package.json
{
  "name": "packageTest",
  "version": "0.1.0-alpha.1",
  "description": "Test package.",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}

正如所料.
