**Summary** vuex-class syntax in class component @leftSidebarModule.Mutation('EditDomainModel') EditDomainModel; @leftSidebarModule.Mutation('EditDomainModelName') EditDomainModelName; when I used parse methods,a error has happened, because the @babel/parser module can't recogize this decorator syntax . the syntax above is vuex-class decorator node.body.body.forEach((property) => { if (property.static) { return; // ignore static members } switch (property.type) { case Syntax.ClassProperty: this.parseClassProperty(property); // the property value is null, cause the processing failed break;
