Yarn Build - Storybook 的 Babel-loader 问题

Yarn Build - Babel-loader issues with Storybook

我有一个新的创建反应应用程序项目,使用打字稿模板:

yarn create react-app my-app --template typescript

为此,我添加了故事书:

npx sb init

这给了我一个可用的故事书实例,但是,yarn build 现在出错了。

$ react-scripts build

There might be a problem with the project dependency tree.
It is likely not a bug in Create React App, but something you need to fix locally.

The react-scripts package provided by Create React App requires a dependency:

  "babel-loader": "8.1.0"

Don't try to install it manually: your package manager does it automatically.
However, a different version of babel-loader was detected higher up in the tree:

  /home/michael/pgit/my-app/node_modules/babel-loader (version: 8.2.2)

Manually installing incompatible versions is known to cause hard-to-debug issues.

If you would prefer to ignore this check, add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
That will permanently disable this message but you might encounter other issues.

To fix the dependency tree, try following the steps below in the exact order:

  1. Delete package-lock.json (not package.json!) and/or yarn.lock in your project folder.
  2. Delete node_modules in your project folder.
  3. Remove "babel-loader" from dependencies and/or devDependencies in the package.json file in your project folder.
  4. Run npm install or yarn, depending on the package manager you use.

In most cases, this should be enough to fix the problem.
If this has not helped, there are a few other things you can try:

  5. If you used npm, install yarn (http://yarnpkg.com/) and repeat the above steps with it instead.
     This may help because npm has known issues with package hoisting which may get resolved in future versions.

  6. Check if /home/michael/pgit/my-app/node_modules/babel-loader is outside your project directory.
     For example, you might have accidentally installed something in your home folder.

  7. Try running npm ls babel-loader in your project folder.
     This will tell you which other package (apart from the expected react-scripts) installed babel-loader.

If nothing else helps, add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
That would permanently disable this preflight check in case you want to proceed anyway.

P.S. We know this message is long but please read the steps above :-) We hope you find them helpful!

所以 babel-loader 不在我的任何 package.json 文件中,babel 应该全部由 CRA 处理(因此警告不要自己添加它。)

我可以使用 SKIP_PREFLIGHT_CHECK - 但这掩盖了潜在的冲突,让两个库先决条件一起玩的正确方法是什么?

这是一个known issue

如果您使用的是纱线,则可以使用分辨率轻松绕过它。 将以下内容添加到您的 package.json 以允许 yarn 解析 babel-loader 版本 8.1.0(CRA 要求的版本,而不是 Storybook):

"resolutions": {
  "babel-loader": "8.1.0"
},

之后,确保 运行 yarn install 刷新您的依赖项并更新 yarn.lock 文件

对于遇到与 npm 相同问题的任何人。我通过删除 package-lock.jsonnode_modules.

来修复它

编辑:通过对 npm inpm dedupe 都使用 --legacy-peer-deps 参数,可以在 package.json 中保留 babel-loader 隐式版本:

npm i --leagcy-peer-deps

为了确保问题出在损坏的依赖树上,我 运行:

npm ls babel-loader

终于

npm dedupe --legacy-peer-deps

修复了依赖树错误的问题。 同样适用于webpack版本不匹配问题

"babel-loader": "8.1.0" 添加到 package.json 文件中的“devDependencies”和“dependencies”,然后使用 yarn 进行构建,似乎从 now.Its 开始工作,这是一个已知问题并且已经开业快2年了https://github.com/storybookjs/storybook/issues/5183
