Javascript SyntaxError:意外标记<；当尝试使用AVA进行测试时

我最初的问题出现在基于nuxt的项目中。为了解决这个问题，我通过vue cli设置了一个新项目，并通过npm再次安装了AVA，但它没有改变任何东西。我在github上发现了这个问题（），其中的一条评论（Atinux的，3月25日）似乎回答了我的问题，但当我尝试转到上面提到的链接时，我得到了404。这篇文章的作者说，他从来并没有想过使用完整的路径，但我真的不明白他的确切意思

我还尝试了几种不同的组件语法，但据我所知，问题出在AVA设置中，因为问题出在第一个“=4.0.0”， “npm”：“>=3.0.0” }, “浏览者”：[ "> 1%", “最后两个版本”，
