What’s causing the error?

The error message "const defaultCommand = “dev”; " not found in "node_modules/.bin/next" typically occurs when there’s a mismatch between the Node.js version installed on your Plesk server and the version required by the Next.js project. This mismatch can lead to a failure to locate the default command, resulting in the error.

Checking Node.js versions

To verify the Node.js version on your Plesk server, follow these steps:

Log in to your Plesk control panel.
Navigate to the Domains tab.
Select the domain experiencing the error.
Click on the Files tab.
In the Files tab, click on the File Manager button.
In the File Manager, navigate to the node_modules directory.
Check the version of Node.js installed by running the command node -v in the terminal.

Updating Node.js versions

If the installed Node.js version is outdated or incompatible with your Next.js project, you’ll need to update it to a compatible version. Here’s how:

Method 1: Update Node.js using Plesk’s built-in feature

Plesk provides an easy way to update Node.js versions. Follow these steps:

Log in to your Plesk control panel.
Navigate to the Domains tab.
Select the domain experiencing the error.

Method 2: Update Node.js using the command line

If the built-in feature doesn’t work, you can update Node.js using the command line. Here’s how:

nvm install node
nvm use node
npm install --global yarn

Replace node with the desired Node.js version (e.g., node14 for Node.js 14).

Verifying Next.js installation

After updating Node.js, ensure that Next.js is properly installed and configured. Follow these steps:

Run the command npm install next in the terminal to install Next.js.
Verify that the next command is available by running next -v in the terminal.
