開始しようとしてエラーが発生しましたReact直後（プロジェクトの依存関係ツリーに問題がある可能性があります...）

React npx create-react-appからアプリを作成しました。そして、アプリをcdして起動しようとすると、このエラーが表示されます。yarnを使用してノードを再インストールしようとしました。 30分前のようにwooooorkingしていたのでスーパーロスト。私がした唯一のことはnpm i -g npmがnpmを更新することで、それ以来それは機能していません。

We suggest that you begin by typing:

  cd giact
  yarn start

Happy hacking!

> react-scripts start


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-eslint": "10.1.0"

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

  /Users/gi/node_modules/babel-eslint (version: 9.0.0) 

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-eslint" 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 /Users/gi/node_modules/babel-eslint is outside your project directory.
     For example, you might have accidentally installed something in your home folder.

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

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!

1）Create React Appが提供するreact-scriptsパッケージには依存関係が必要です：

"babel-eslint"： "10.1.0"、 "eslint"： "^ 6.8.0"

コマンドを使用：npm install [email protected] babel-eslint @ 10 --save-dev

私はいくつかのステップを踏み、その仕事をしてくれました。

ステップ1：D driveに保存したかのようにプロジェクトの場所を変更し、E driveに変更します。

ステップ2：ノードモジュールを削除します。

ステップ3：このコマンドを実行してノードモジュールをインストールする>> npm install

私の問題は、「C：\ Users」フォルダにあるnode_modulesを削除することで解決しました。
