The Engine “Node” is Incompatible with This Module Error

For NodeJS development, it's common to encounter errors, and one of these is, "The engine node is incompatible with this module." Usually, it is a result of the version of NodeJS you are using against the version the module or package needs as mentioned in the project dependencies or package.json. This may be because of some restrictions on the engine that prevents running certain modules in incompatible versions of NodeJS.

That means the node version installed on your system is incompatible with the version of your project. To resolve this issue, you must upgrade your NodeJS to the corresponding version specified for the project. Usually, your error looks something like:

It indicates that the module you're trying to install or run requires a specific version of NodeJS that differs from your current version.

The primary reason behind this error is the engine field in your package.json file. This field specifies which versions of NodeJS your project is compatible with, preventing potential runtime issues caused by version incompatibility.

Look through the documentation of the package or its README for the version of NodeJS it requires; there might be an entire section labeled something like "System Requirements" or "Prerequisites."

Once you upgrade or downgrade the version of NodeJS to be in line with that specified in package.json, you can manage different versions using tools such as [nvm (Node Version Manager)]. You can quickly change the different versions of NodeJS in the project per the requirement.

Make use of a version manager like nvm to install the version of NodeJS you need. For example, if it's 12. x you need, install it in that way

Using 'nvm':

Now, try running your application. The compatibility issue should be resolved.

Keep in mind that some packages or modules may have strict compatibility requirements with certain NodeJS versions. Therefore, it's crucial to ensure you have the correct version installed. If you run into any problems during the installation or setup process, be sure to consult the package or module's documentation for more detailed guidance.

If you need to bypass this check temporarily, you might use the flag --ignore-engines with yarn or --engine-strict=false with npm, though it is not recommended because there is a chance for runtime problems.
