我的应用程序工作很好，直到我更新了反应脚本。更新后，每次我尝试运行应用程序时都会显示此错误。项目依赖树可能有问题。这可能不是Create React App中的bug，而是需要在本地修复的bug。
Create React App提供的React -scripts包需要依赖项:
"babel-jest"^ 26.6.0"
不要尝试手动安装:你的包管理器会自动安装。然而，在树的更高位置检测到一个不同版本的babel-jest:
C:UsersDigital DividendDesktopAccurator Accurator node_modulesbabel-jest (version: 27.2.5)
手动安装不兼容的版本会导致难以调试的问题。
如果您希望忽略此检查，请将SKIP_PREFLIGHT_CHECK=true添加到项目中的.env文件中。这将永久禁用此消息，但您可能会遇到其他问题。
要修复依赖树，请尝试按照下面的顺序执行步骤:
- 删除package-lock。Json(不是package.json!)和/或yarn. Json。
- 删除项目文件夹中的node_modules。
- 删除"babel-jest"从包中的dependencies和/或devDependencies中获取。
- 运行npm install或yarn，这取决于你使用的包管理器。
在大多数情况下，这应该足以解决问题。如果这没有帮助，您可以尝试其他一些方法:
-
如果你使用的是npm，请安装yarn (http://yarnpkg.com/)并重复上面的步骤。这可能会有所帮助，因为npm在包提升方面有一些已知的问题，这些问题可能会在未来的版本中得到解决。
-
检查C:UsersDigital DividendDesktopAccurator Accurator node_modulesbabel-jest是否在你的项目目录之外。例如，您可能不小心在主文件夹中安装了一些东西。
-
尝试在你的项目文件夹中运行npm ls babel-jest。这将告诉您安装babel-jest的其他包(除了预期的react-scripts)。
如果没有其他帮助，将SKIP_PREFLIGHT_CHECK=true添加到项目中的.env文件中。如果你想继续飞行，这将永久禁用飞行前检查。

尝试删除你的node_modules和你的。lock文件，然后做一个yarn/npm安装之后
你可能还需要将"babel-jest": "^26.6.0"替换为"babel-jest": "27.3.1"并运行npm/yarn install
