Troubleshoot linting and Bootstrap issues in Dreamweaver
Follow this procedure to troubleshoot linting and Bootstrap issues that occur in Adobe Dreamweaver 2015.

Linting and Bootstrap issues in Dreamweaver 2015

  • Unable to lint the code. Dreamweaver displays an error in the Output panel: "Cannot lint the code." On Mac 10.10, the output panel displays "Linting operation timed out".
  • Unable to create a Bootstrap document. Dreamweaver displays the error, "Cannot create a new document as Bootstrap customization failed."


  1. Restart Dreamweaver. If Dreamweaver was unable to create the node server instance, restarting Dreamweaver addresses the issue.

    If restarting doesn't help, proceed with the following steps.

  2. Assign a specific port for the services from the node server (including linting). Ensure that this port is not blocked by your system administrator. To do this, create a file NodePort.json, and specify the port number in the file in the following format:

    “toolingport” : <portnumber>

    For example, if 8010 is the port number that you want to use, then specify the following:

    “toolingport” : 8010


    If you have already created a NodePort.json file with a key value pair in it, use comma to separate the new key value pair or specify the new key value pair in a separate line.

  3. Save the NodePort.json file in the following path:

    • Windows: %appdata%\Adobe\Dreamweaver CC 2015\en_US\Configuration
    • Mac OS~/Library/Application Support/Adobe/Dreamweaver CC 2015/en_US/Configuration
  4. Restart Dreamweaver.

  5. If you still get an error message, contact your system administrator to unblock the IP address of the node server: Then, restart Dreamweaver.

Additional information

  • The random port assigned by the node server.
  • The IP address of the server is
