Jestjs Jest配置能够使用节点模块源运行测试

我有两个项目：

应用程序

库（用于共享代码）

在我的应用程序中，我有一个测试直接使用我的npm包库的源代码

从'@xxx/library/src/entities/address'导入{mockAddress}

问题
Jest遇到了意外的标记

This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.

By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".

Here's what you can do:
 • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
 • If you need a custom transformation specify a "transform" option in your config.
 • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config

选择权

我试过的
我试图将我的库文件夹添加到
transformIgnorePatterns

  transformIgnorePatterns: [
    '<roodDir>/node_modules/(?!vee-validate/dist/rules)',
    '<roodDir>/node_modules/(?!@xxx/library/src)',
  ],

编辑1
jest.config
您的transformIgnorePatterns是相互排斥的。节点应该只有一个模式_modules@EstusFlask我确实更改了编辑1，但仍然是相同的“node_modules/（？！vee validate/dist/rules |@xxx/lib/）”，。我不确定是否需要添加beforerootDir不会有帮助，因为这样做限制更大。路径过多并且没有考虑反斜杠，
/
应该是
[/\\\\]
。你的意思是用
[/\\\]
替换所有的
//\\\\\\\\]
，所以它应该是`节点单元模块[/\\\]（？！vee validate[/\\\\\\\]dist[/\\\\\]规则.@xxx[/\\\\\\\\]lib[/\]'）``？我直接使用库中的源代码，这可能是一个问题吗？
