我尝试为 React 项目创建构建文件夹，但是当我运行命令“npm run build”时出现此错误

(base) tazar@Tazs-Air nft-minter-tutorial-main % npm run build
npm ERR! Missing script: "build"
npm ERR!

在 package.json 文件中添加构建脚本，例如：

"scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },

in your package.json file add build script, for example:

"scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },

您可以检查标准的react package.json（位于项目的根文件夹中）文件：

{
  "name": "print",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

You can check standard react package.json(which is located in root folder of your project) file:

{
  "name": "print",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

如果在 package.json 文件中定义了构建，请确保您在正确的文件夹层次结构中执行“npm run build”（使用不带参数的“cd”或“pwd”）。

我在运行命令时遇到了同样的问题

npm run build

我发现我在错误的文件夹中运行命令，因此出现了错误。当我移动到主项目的文件夹并运行相同的命令时，它工作得很好。
我认为你也犯了同样的错误。
例如：
如果您创建了一个文件夹 new_project，然后在该文件夹（new_project）中创建了 React 应用程序，例如 npx create-react-app project_folder

那么您必须始终在此特定文件夹中运行该命令

npm run build

。

I was facing the same issue while running the command

npm run build

What I found was that I was running the command in the wrong folder and hence the error was sited. When I moved to the folder of my main project, and ran the same command it worked perfectly.
I think you are making the same mistake.
For eg:
If you have created a folder new_project, and then have created the react app in the folder(new_project) say, npx create-react-app project_folder

Then you must always run the command
