描述
¥Description
像 npm install 和 package.json 中的依赖部分这样的命令使用包名称说明符。这可以是许多不同的东西，都指的是 "包"。示例包括包名称、git url、tarball 或本地目录。在使用此包名称说明符的 npm 命令的帮助输出中，这些通常称为 <package-spec>。
¥Commands like npm install and the dependency sections in the package.json use a package name specifier. This can be many different things that all refer to a "package". Examples include a package name, git url, tarball, or local directory. These will generally be referred to as <package-spec> in the help output for the npm commands that use this package name specifier.
包名
¥Package name
-
[<@scope>/]<pkg> -
[<@scope>/]<pkg>@<tag> -
[<@scope>/]<pkg>@<version> -
[<@scope>/]<pkg>@<version range>
按名称引用包，有或没有范围，以及可选的标记、版本或版本范围。这通常与 注册表 配置 结合使用以引用注册表中的包。
¥Refers to a package by name, with or without a scope, and optionally tag, version, or version range. This is typically used in combination with the registry config to refer to a package in a registry.
示例：
¥Examples:
-
npm -
@npmcli/arborist -
@npmcli/arborist@latest -
npm@6.13.1 -
npm@^4.0.0
别名
¥Aliases
<alias>@npm:<name>
主要由 npm install 之类的命令和 package.json 的依赖部分使用，this 通过别名引用包。<alias> 是在 node_modules 文件夹中具体化的包的名称，而 <name> 指的是在配置的注册表中找到的包名称。
¥Primarily used by commands like npm install and in the dependency sections in the package.json, this refers to a package by an alias. The <alias> is the name of the package as it is reified in the node_modules folder, and the <name> refers to a package name as found in the configured registry.
有关按名称引用包的更多信息，请参阅上面的 Package name，而 注册表 用于配置在按名称引用包时使用哪个注册表。
¥See Package name above for more info on referring to a package by name, and registry for configuring which registry is used when referring to a package by name.
示例：
¥Examples:
-
semver:@npm:@npmcli/semver-with-patch -
semver:@npm:semver@7.2.2 -
semver:@npm:semver@legacy
文件夹
¥Folders
<folder>
这是指本地文件系统上的包。具体来说，这是一个包含 package.json 文件的文件夹。这应该始终以 / 或 ./（或你的操作系统等效项）为前缀，以减少混淆。npm 当前会将包含多个 / 的字符串解析为文件夹，但这是可能在未来版本中删除的旧版行为。
¥This refers to a package on the local filesystem. Specifically this is a folder with a package.json file in it. This should always be prefixed with a / or ./ (or your OS equivalent) to reduce confusion. npm currently will parse a string with more than one / in it as a folder, but this is legacy behavior that may be removed in a future version.
示例：
¥Examples:
-
./my-package -
/opt/npm/my-package
压缩包
¥Tarballs
-
<tarball file> -
<tarball url>
示例：
¥Examples:
-
./my-package.tgz -
https://registry.npmjs.org/semver/-/semver-1.0.0.tgz
指的是 tarball 格式的包，可以在本地文件系统上或通过 url 远程。这是上传到注册表时包存在的格式。
¥Refers to a package in a tarball format, either on the local filesystem or remotely via url. This is the format that packages exist in when uploaded to a registry.
git url
-
<git:// url> -
<github username>/<github project>
指 git repo 中的包。这可以是完整的 git url、git 速记或 GitHub 上的用户名/包。你可以通过附加 #ref 来指定 git 标记、分支或其他 git ref。
¥Refers to a package in a git repo. This can be a full git url, git shorthand, or a username/package on GitHub. You can specify a git tag, branch, or other git ref by appending #ref.
示例：
¥Examples:
-
https://github.com/npm/cli.git -
git@github.com:npm/cli.git -
git+ssh://git@github.com/npm/cli#v6.0.0 -
github:npm/cli#HEAD -
npm/cli#c12ea07
