7 years ago Never seen this. I can't even tell if it is related to collapse or your project. Could be some browserify-related thing. I do not use browserify and do only webpack, so I cannot help unless you have some minimal repo with this error I can try myself
I'm using React collapse in my project, version 2.2.4 with react 0.14.8. When It is loaded I have this problem.
TypeError: Super expression must either be null or a function, not undefined application.jsI changed react to newest version and react-collapse too. Even with the change, this problem persists. I found this link which appears to be useful for me, but no success.
This is the function where error occurs:
function _inherits(subClass, superClass) { if (typeof superClass !== "function" && superClass !== null) { throw new TypeError("Super expression must either be null or a function, not " + typeof superClass); } subClass.prototype = Object.create(superClass && superClass.prototype, { constructor: { value: subClass, enumerable: false, writable: true, configurable: true } }); if (superClass) Object.setPrototypeOf ? Object.setPrototypeOf(subClass, superClass) : subClass.__proto__ = superClass; }And those are the dependencies:"dependencies": { "babelify": "7.2.0", "browserify": "12.0.1", "browserify-incremental": "3.0.1", "jquery": "2.2.0", "react": "0.14.8", "react-bootstrap": "0.28.1", "react-collapse": "2.2.4", "react-dom": "0.14.3", "react-height": "2.1.0", "react-highcharts": "8.0.2", "react-motion": "0.4.4", "react-select": "1.0.0-beta12", "react-sticky-position": "2.0.0", "screenfull": "3.0.0" }
