React Material Admin Template

María Camila Bernal

I bought the react-material-admin-full-v2.3.3 template, I followed the steps in the Readme, but when I give "yarn start" it throws me an error:

yarn run v1.22.19 $ react-scripts start node:internal/modules/cjs/loader:556 throw e; ^

Node.js v19.5.0

I have the versions: $ node --version v19.5.0

$ npm --version 9.3.1

Can you help me?

You need to use version 16 of nodejs to run this template

I dont't now what is the problem.

Please, help me

María Camila Bernal

I was using the V16 for nodeJS after your recommendation, but the template is not working yet

Alexandr

"/bin/sh: 1: cross-env: not found" Did you get this error after installing dependency via 'yarn install'?

If you're having trouble starting the instance of your React Material Admin template, there are a few steps you can take to troubleshoot the issue:

Check Dependencies: Ensure that you have all the necessary dependencies installed for the template. This includes Node.js, npm or yarn, and any other specific dependencies mentioned in the template's documentation.
Install Packages: Run npm install or yarn install in the project directory to install all required packages.
Configuration: Double-check if any configuration files need adjustments, such as environment variables or configuration files specific to the template.
Start Script: Check the start script specified in the template's package.json file. It's usually something like npm start or yarn start. Run this command in your terminal.
Check for Errors: Pay close attention to any error messages in the terminal when you try to start the instance. They often provide valuable clues as to what might be going wrong.
Port Conflict: Ensure that the port specified in the template is not in use by another application. By default, React applications often use port 3000. If that port is occupied, you can specify a different port by setting the PORT environment variable.
Firewall Issues: Sometimes, firewall settings or antivirus software can interfere with the instance startup. Make sure your firewall isn't blocking the application.
Clear Cache: If you've previously attempted to start the instance, there might be a caching issue. Try clearing the cache by running npm cache clean --force or yarn cache clean.
Update Dependencies: Check if there are any updates available for the template's dependencies by running npm outdated or yarn outdated. If there are, update them and try starting the instance again.
Community Support: If none of the above solutions work, consider reaching out to the template's support community or forum. Often, other users or the template developers themselves can provide guidance or solutions to common issues.

By following these steps, you should be able to identify and resolve the issue preventing you from starting the instance of your React Material Admin template.
