Javascript '；Jest在react应用程序上遇到意外的令牌{'；错误

我似乎无法克服这个问题。我已经尝试了所有我可以在网上找到的关于这个问题的方法（很多！），但它似乎无法解决。以下是配置

这一行表示您的babel没有传输es模块语法

尝试
模块：“cjs”

  const presets = [
    ["@babel/preset-env", {"modules": 'cjs'}],
    ["@babel/preset-flow", {"all": true}],
    "@babel/preset-react",
  ]

似乎您的ts配置没有正确使用babel jest！请尝试使用
“transform”：{“^.+\\（js|ts）x？$”：“babel jest”}
@springer如果你使用的是typescript还是只有babel？我忘了提到我没有使用typescript，只是使用了带有jsnot sur的babel，但是，如果没有加载配置jest，或者包中没有识别babel jest。json请尝试添加jst配置的位置
--config./jest.config.json
，如下所示<代码>{“脚本”：{“测试”：“jest--config./jest.config.json--no cache”，“测试：监视”：“npm运行测试----watch”}，…
