[英]NPM Install add custom warning message
How should I got about adding a warning message when a user tries to install a given version of a library?当用户尝试安装给定版本的库时,我应该如何添加警告消息?
For example, when you install babel-preset-es2015
you get the following warning:例如,当您安装
babel-preset-es2015
您会收到以下警告:
🙌 Thanks for using Babel: we recommend using babel-preset-env now: please read babeljs.io/env to update!
🙌 感谢您使用 Babel:我们现在推荐使用 babel-preset-env:请阅读 babeljs.io/env 更新!
By inspecting their code I saw they add a deprecated
entry in their package.json as follows:通过检查他们的代码,我看到他们在 package.json 中添加了一个
deprecated
条目,如下所示:
"deprecated": "🙌 Thanks for using Babel: we recommend using babel-preset-env now: please read babeljs.io/env to update! ",
I can easily add that, but I'm not actually deprecating anything.我可以很容易地添加它,但我实际上并没有贬低任何东西。 I just want to warn users that they are installing an alpha version and there may be changes in the API.
我只是想警告用户他们正在安装一个 alpha 版本,API 可能会有变化。
Question问题
Is there a similar entry to deprecated
that can do the job?是否有类似的
deprecated
条目可以完成这项工作?
There's not necessarily a way you can do that, or not with given fields like "deprecated"
不一定有一种方法可以做到这一点,或者不能使用
"deprecated"
类的给定字段
What you can do, which is a little bit of a workaround, is adding a post-install script , that outputs a string to the console if you mark a version as alpha.您可以做的,这是一种解决方法,是添加一个安装后脚本,如果您将版本标记为 alpha,它将向控制台输出一个字符串。
// package.json
{
"version": "1.2.3-alpha.2",
"scripts": {
"postinstall": "node postinstall.js"
}
}
// postinstall.js
const package = require('./package.json')
if (package.version.includes('alpha')) {
console.log('You are using an alpha version. Beware!')
}
Please check out belows:请查看以下内容:
$ npm deprecate <pkg>[@<version>] <message>
Example:示例:
$ npm deprecate some-lib@"< 1.0.0" "🙌 Thanks for using it. we recommend using new version, 1.x.x. Please check out https://example.com"
then,那么,
$ yarn
yarn install v1.16.0
