我试过了

meteor npm install --save classnames

然而，错误不断出现。知道问题可能是什么以及如何解决？

Answer 1

您需要为我们提供更多代码来帮助您。乍一看，您似乎已将React组件转换为类并保留了displayName属性。

您应该从React ES6组件定义中删除displayName。

我不认为类名会让你遇到麻烦。

npm i --save classnames

当你想要使用它时：

import classNames from 'classnames';

请记住将导入保留在文件的目标位置。

更新后，Meteor 1.3与TypeError崩溃
