我偶然发现的问题，如“无法解决主package.json文件”使用NextJS与Jest.我已经尝试使用jest.config.js与Babel和它的工作，但'下一个/jest'变种不工作.感谢您的帮助：）
：：：：：jest.config.js：：：：：

const nextJest = require('next/jest')
const { pathsToModuleNameMapper } = require('ts-jest')
const { compilerOptions } = require('./tsconfig.json')

const createJestConfig = nextJest({
  dir: '/'
})

const customJestConfig = {
  moduleDirectories: ["node_modules", "<rootDir>/", "<rootDir>/src"],
  moduleNameMapper: pathsToModuleNameMapper(compilerOptions.paths),
  testEnvironment: "jest-environment-jsdom"
}

module.exports = createJestConfig(customJestConfig)

：：：：：package.json：：：：

{
  // omitted unnecessary
  "scripts": {
    "test": "jest --watch",
  },
  "dependencies": {

错误信息：error log
它使用以下jest.config.js配置
