npm 安裝拋出錯誤

Question

我試圖使用 React 進行視頻會議，但在安裝npm start不起作用。 它在我的終端中顯示：

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:

  C:\Users\Vatsal\node_modules\babel-eslint (version: 10.0.0)

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 C:\Users\Vatsal\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!

npm ERR! code ELIFECYCLE

我所做的是嘗試在全球范圍內安裝 webpack。 我還嘗試了一些來自互聯網的建議以及終端中的建議，但沒有任何幫助。

只需按照錯誤日志中給出的確切說明進行操作：

要修復依賴關系樹，請嘗試按確切順序執行以下步驟：

1. 刪除項目文件夾中的 package-lock.json（不是 package.json。）和/或 yarn.lock。
2. 刪除項目文件夾中的 node_modules。
3. 從項目文件夾中 package.json 文件中的依賴項和/或 devDependencies 中刪除“babel-eslint”。
4. 運行 npm install 或 yarn，具體取決於您使用的 package 管理器。
