Question

我在运行react-script test时发现了此错误消息

The react-scripts package provided by Create React App requires a dependency“ babel-jest”：“ ^ 24.9.0”`

因此，该错误消息还建议我们删除package-lock.json以及我尝试过的node_modules，但是我有相同的错误消息。

然后我检查package-lock.json，例如jest-config（是子依赖项）使用的版本高于react-script接受的版本。

如果您有任何建议，请

packages.json

Answer 1

create-react-app遇到了同样的问题。这是我所做的

转到路径

C:\Users\YOURNAME\node_modules

，然后删除那些显示错误的软件包。

Answer 2

具有讽刺意味的是，今天早上我正在研究一个类似的问题。您能否提供package.json和错误消息的屏幕截图？

Babel-Jest用于将javascript代码编译为jest可以使用的格式。我怀疑您的问题是您依赖于锁定文件随后锁定了错误版本的babel-jest。

Answer 3

我可以从上述响应中添加更多详细信息，以解决我发现的问题。

当我们使用react-scripts时，我们无法获得开玩笑的程序包，或者已经由create-react-app管理的东西

我遇到的问题是package.json包含比react-script可接受的更高版本的笑话

当我删除package.json中的这一行时，它似乎已经可以工作了

Answer 4

您的一个依赖项是使用babel-jest的较新版本。您可以通过在项目根目录中运行npm ls babel-jest来找到它们。

然后解决此问题的一种简单方法是尝试链接到这些软件包的旧版本，例如"@types/jest": "^24.0.0"，以便他们不使用更新版本的babel-jest。

Answer 5

mac 用户删除

/Users/{UserName}/node_modules

Create React App提供的react-scripts包需要依赖：Babel-Jest
