Cannot find module 'lws/lib/usage'

I am using lws for mocking some API endpoints and everything worked fine until I’ve removed node_modules and ran npm install again. Now starting the server (ws -c mock-server/lws.config.js) throws this error:

Error: Cannot find module 'lws/lib/usage'
    at Function.Module._resolveFilename (module.js:555:15)
    at Function.Module._load (module.js:482:25)
    at Module.require (module.js:604:17)
    at require (internal/module.js:11:18)
    at MockResponse.middleware (...\node_modules\lws-mock-response\index.js:42:21)
...

The configuration file (mock-server/lws.config.js) is very small :

module.exports = {
    port: 8789,
    mocks: require('./mocks')
};

where mocks.js exports a lambda following the pattern from the documentation:

module.exports = MockBase => class MockService extends MockBase {
    mocks(options) {
        return [...]; // several route configurations
    }
};

I’ve looked in node_modules/lws/lib and indeed there is no usage.js file.

Am I missing something here or is it a regression from the lws-mock-response module?

@tylermassey If a project is for some reason locked to version 2.5.2, a workaround would be to manually add a dependency to “lws” version 1.2.6 in order to prevent that issue from happening.

I’ve reinstalled and everything works fine now. Thank you very much for the quick response and fix!
