VSCode TypeScript 模块识别异常排查方案

错误提示：Cannot find module 'rxjs/internal/observable/of'. Did you mean to set the 'moduleResolution' option to 'node', or to add aliases to the 'paths' option?
已知前提：终端执行TS相关命令运行正常，同仓库其他开发人员均出现相同问题，当前根目录tsconfig配置如下：

{
  "compileOnSave": false,
  "compilerOptions": {
    "rootDir": ".",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "importHelpers": true,
    "target": "es2015",
    "module": "esnext",
    "lib": ["es2017", "dom"],
    "skipLibCheck": true,
    "skipDefaultLibCheck": true,
    "baseUrl": ".",
    "paths": {
      "@nx-fornida/amz": ["libs/amz/index.ts"],
      "@nx-fornida/client-logic/orders": [ "libs/client-logic/orders/src/index.ts" ],
      "@nx-fornida/common-libs/error-handler": [ "libs/common-libs/error-handler/src/index.ts" ],
      "@nx-fornida/client-logic/amz-reports": [ "libs/client-logic/amz-reports/src/index.ts" ],
      "@nx-fornida/components": ["libs/frontend/components/src/index.ts"],
      "@nx-fornida/custom-collections-node": [ "libs/custom-collections-node/src/index.ts" ],
      "@nx-fornida/frontend-auth": ["libs/frontend/auth/src/index.ts"],
      "@nx-fornida/frontend-common": ["libs/frontend/common/src/index.ts"],
      "@nx-fornida/frontend-core": ["libs/frontend/core/src/index.ts"],
      "@nx-fornida/frontend-layout": ["libs/frontend/layout/src/index.ts"],
      "@nx-fornida/frontend-themer": ["libs/frontend/themer/src/index.ts"],
      "@nx-fornida/interface/amz": ["libs/interfaces/amz.interface"],
      "@nx-fornida/interface/bigcommerce": ["libs/interfaces/bc.interface"],
      "@nx-fornida/interface/customcollections": [ "libs/interfaces/customcollections.interface.ts" ],
      "@nx-fornida/interface/errorhandler": [ "libs/interfaces/errorhandler.interface" ],
      "@nx-fornida/interface/parts": ["libs/interfaces/parts.model"],
      "@nx-fornida/interface/retail": ["libs/interfaces/retail.interface"],
      "@nx-fornida/selling-partners-sdk": [ "libs/selling-partners-sdk/src/index.ts" ],
      "@nx-fornida/suggested-retail": ["libs/suggested-retail/src/index.ts"],
      "@nx-fornida/ui": ["libs/frontend/ui/src/index.ts"],
      "@nx-fornida/views/amz-orders": [ "libs/frontend/views/amz-orders/src/index.ts" ]
    }
  },
  "exclude": ["node_modules", "tmp"]
}

校验TS版本一致性：打开任意.ts文件，点击VSCode右下角的TypeScript版本号，选择「使用工作区版本」，避免VSCode自带的全局TS版本和项目package.json中安装的TS版本规则不兼容。
验证tsconfig生效范围：当前配置未显式声明include字段，默认包含根目录下所有.ts文件，若项目子目录存在单独的tsconfig.*.json配置，可在命令面板（Ctrl+Shift+P / Cmd+Shift+P）执行「TypeScript: Go to Project Configuration」，确认当前报错文件关联的tsconfig是否正确。
排查导入写法问题：rxjs官方推荐的公共API导入路径为import { of } from 'rxjs'，若代码中直接使用rxjs/internal/xxx这类内部路径导入，会出现类型声明路径和运行路径不匹配的问题，终端编译正常是因为构建工具做了路径兼容，TS类型检查会严格校验类型声明位置，建议修改为官方公开的导入写法。
重置TS服务缓存：执行命令面板的「TypeScript: Restart TS Server」重启TS服务，若仍未解决可执行「Developer: Reload Window」重载窗口，清除缓存的类型解析结果。
校验依赖完整性：删除node_modules目录和对应包管理工具的lock文件（package-lock.json/yarn.lock/pnpm-lock.yaml）后重新安装依赖，排除rxjs类型声明文件损坏的可能。
