Could not find org.webjars.npm:js-tokens:[3.0.0,4),[4.0.0,5)


Enonic version: YourEnonicVersion
OS: YourOS

Trying to run the ‘./gradlew build’ command on the coreui starter-pack. Get a build failure then.

  • What went wrong:
    A problem occurred configuring root project ‘coreui’.

Failed to notify project evaluation listener.
Could not resolve all dependencies for configuration ‘:webjar’.
Could not find org.webjars.npm:js-tokens:[3.0.0,4),[4.0.0,5).

Some one know how I can resolve this issue?

Thx :slight_smile:



There seems to be a broken package or something when using react with webjar.
Add the following lines to the bottom of you’re build.gradle file to fix the build problem.

configurations.each {
    c -> c.resolutionStrategy.dependencySubstitution {
        all { DependencySubstitution dependency ->
            if ( == 'org.webjars.npm') {
                dependency.useTarget 'org.webjars.npm:js-tokens:3.0.2'



Hi, that seemed to fix the original problem, but after implementing the fix and running a New build, another error occured.

Not sure how to continue here :slight_smile:


It says it can’t find Python to rebuild some binary for your environment. You either don’t have Python installed or you don’t have an environment variable specifying where to find Python.

If you have Python installed, you can set the path to Python in the Windows Control Panel. If you don’t have Python installed you have a lot of options.
