Error: command “npm run build” exited with 1

Error: command “npm run build” exited with 1

This error typically occurs when there is a problem with the build script in your npm package.json file or when there are issues with the dependencies required for the build process.

The exit code 1 indicates that the build process failed. When a command exits with a non-zero code, it usually means that there were errors during the execution of the command.

To troubleshoot this error, here are some steps you can follow:

1. Check the build script in your package.json file to ensure it is correctly defined. Make sure you have the necessary build commands and that they are executing the correct tasks.
2. Verify that all required dependencies for the build process are installed. Use the npm install command to install any missing dependencies.
3. Inspect the error message or stack trace provided with the error. It can give you valuable information about what went wrong during the build process.
4. Check if there are any other error messages or warnings preceding this error. Sometimes, an earlier issue can cause subsequent errors.
5. Review the documentation or community forums for the specific tools or libraries you are using in your build process. Others may have encountered a similar issue and found a solution.
6. Try running the build command in a clean environment. Remove any temporary files or folders that may have been generated during previous build attempts.

Here is an example scenario to better illustrate the issue:

    
// package.json
{
  "name": "my-app",
  "version": "1.0.0",
  "scripts": {
    "build": "webpack"
  },
  "devDependencies": {
    "webpack": "^5.1.0"
  }
}
    
  

In this example, the build script is defined to use webpack for the build process. However, the required webpack dependency is not installed. Running “npm run build” would result in the mentioned error. To fix it, we need to install webpack by running “npm install webpack –save-dev”.
