最近我将我的黄瓜版本从3.1.2升级到4.1。现在，我无法从Intellij执行测试用例。错误是：

因此，由于上述错误，我无法执行黄瓜测试用例。测试用例用红宝石编写。
但是如果我执行类似bundle exec cucumber --name <scenario-number>这样的测试用例，就可以了
如何解决此错误？这是插件问题吗？

这是一个问题，您在钩子（或类似地方）中正在做日志行或调用<input asp-for="D_From" type="date" onchange="myFunction()" id="dfrom" min="1945-01-01" max="9999-12-31" class="form-control">
<input asp-for="D_To" type="date" id="dto" class="form-control">
<script type="text/javascript">
function myFunction() {
var x = document.getElementById("dfrom").value;
document.getElementById("dto").min = x;
var month = x.split('-')[1]; // chosen month
var d = new Date(2008, month, 0);
var lastDay = d.getDate(); // last day of month
var maxDate = x.split('-')[0] + '-' + x.split('-')[1] + '-' + lastDay;
document.getElementById("dto").max = maxDate;
}
</script>
或类似内容的行。
这是从v3-> v4升级的已知问题

通过注释\ teamcity \ cucumber \ cucumber_4_formatter.rb step_node_name方法中的以下行，我能够“解决”此问题：
"#{@ast_lookup.step_source(test_step).step.keyword}#{test_step.text}"
请注意，您将无法看到RubyMine执行步骤的名称。
