15、使用标签

Tags are a supplement to semver (e.g., v0.12) for organizing and labeling different versions of packages. In addition to being more human-readable, tags allow publishers to distribute their packages more effectively. ## 添加标签（tag） To add a tag to a specific version of your package, use **npm dist-tag add @ []**. See the CLI docs for more information. ## 使用标签（tag）发布 By default, **npm publish** will tag your package with the **latest** tag. If you use the --tag flag, you can specify another tag to use. For example, the following will publish your package with the beta tag: ~~~ npm publish --tag beta ~~~ ## 使用标签（tag）安装 Like npm publish, npm install will use the latest tag by default. To override this behavior, use npm install @. The following example will install the somepkg at the version that has been tagged with beta. ~~~ npm install somepkg@beta ~~~ ## Caveats Because dist-tags share the same namespace with semver, avoid using any tag names that may cause a conflict. The best practice is to avoid using tags beginning with a number or the letter "v".
