Having searched for similar problems I thought it could be dependency issue, however, after using ‘Yarn’ to install dependencies I still get the same problem. And building locally with "yarn build" works fine.

Solution

  • I found the same error when trying to deploy my single-page React JS web applications to Netlify.

    Following is the procedure I followed to solve the issue and successfully deploy the site.

    1. Go to Site Settings.

      Site Settings

    2. Select Build & Deploy dropdown from the menu.

    3. Select Continuous Deployment tab from the dropdown.

    4. Under the section Build Settings, Select Edit settings.

      • Change the build command as CI= npm run build
      • Click Save.

      Build Settings

    5. Then select Environment tab from the dropdown.

      • Select Edit variables.
      • As the Key enter CI and, as the value enter false.
      • Click Save.

      Environment Settings

    6. Finally retrying the deploying the site again.

    This will help you to solve the issue related to hosting 'Rect JS' Applications in Netlify & your application will be deployed successfully.
