Process ‘command ‘node” finished with non-zero exit value 1

Explanation:

When you encounter the error message “process ‘command ‘node” finished with non-zero exit value 1″ it means that the Node.js process you executed returned a non-zero exit code.

An exit code of 0 usually indicates a successful execution, while a non-zero exit code signifies an error or abnormal termination of the process.

This error can occur due to various reasons:

1. Missing or incorrect dependencies: Check whether all the required dependencies are installed correctly, and there are no issues with versions or compatibility.
2. Syntax or logical errors: Verify your code for any syntax errors, such as missing or extra brackets, or logical errors that may cause the process to terminate abruptly.
3. File or path issues: Ensure that the files or paths referenced in your code are valid and accessible.
4. Memory or resource constraints: In some cases, the process may require more memory or system resources than available. You can try adjusting the memory limits or optimizing your code.
5. External factors: Certain external factors like system configuration, permissions, or conflicts with other processes can also lead to this error.

To troubleshoot the specific cause, it is recommended to:

1. Inspect the error message, as it may provide additional details or stack traces.
2. Review your code and any relevant logs for potential issues that could lead to a non-zero exit code.
3. Search for similar errors or known issues related to the specific Node.js modules or libraries you are using.
4. Experiment with isolating or simplifying the code to narrow down the root cause.

Here is an example to illustrate the situation:

// Example JavaScript code with a deliberate error
const x = 10;
console.log("The value of x is: " + y); // 'y' is not defined

If you try to execute this code using Node.js, you will encounter the stated error message:

node example.js
// Output:
// ReferenceError: y is not defined
//     at Object.<anonymous> (example.js:3:34)
//     ... (remaining stack trace)
// process 'command 'node'' finished with non-zero exit value 1

The error occurred due to the usage of an undefined variable ‘y’. By fixing this error and executing the code again, you can resolve the non-zero exit issue.
