Question

我想运行我的jest测试，但总是在下面看到错误消息，如何才能使我的笑话测试运行？

●测试套件无法运行需要Babel“ ^ 7.0.0-0”，但已加载“ 6.26.3”。如果您确定拥有@ babel / core的兼容版本，则可能是您的构建过程中正在加载错误的版本。检查此错误的堆栈跟踪，以查找第一个未提及“ @ babel / core”或“ babel-core”的条目，以了解正在调用的Babel。在throwVersionError（node_modules/@babel/helper-plugin-utils/lib/index.js：65：11）

我已经按照这里的指示进行了操作，但是仍然没有喜悦。

我有同样的问题。升级到jest@24.0.0对我有用。

开玩笑的错误，需要Babel“ ^ 7.0.0-0”，但已加载“ 6.26.3”
