# 排查与解决步骤

## 1. 修正次级入口目录结构
报错显示ng-packagr在`src/animations`下额外查找`src`子目录，说明次级入口结构不符合预期。正确结构应为：

ngx/
src/
animations/
public_api.ts // 直接放在animations目录下
package.json
lib/
...
public_api.ts
package.json

移除`src/animations`下多余的嵌套`src`文件夹，将`public_api.ts`直接置于次级入口根目录。

## 2. 检查次级入口package.json配置
打开`src/animations/package.json`，确保`entryFile`路径正确指向当前目录下的入口文件：
```json
{
  "ngPackage": {
    "entryFile": "public_api.ts"
  },
  "name": "ngx/src/animations"
}

避免写成src/public_api.ts（除非确实存在嵌套结构）。

3. 调整tsconfig文件规则 #

根目录tsconfig.json需确保包含次级入口的所有文件：

"include": [
  "src/**/*.ts",
  "src/animations/**/*.ts"
],
"exclude": [
  "node_modules",
  "dist"
]

如果次级入口有单独的tsconfig.animations.json，也要保证其include规则覆盖自身目录的文件。

4. 清理构建缓存 #

执行命令清理缓存，避免旧构建残留干扰：

rm -rf node_modules/.cache
ng build ngx --configuration production --clean

5. 验证版本兼容性 #

确保ng-packagr版本与Angular CLI版本匹配（Angular 14+建议使用ng-packagr 14+版本），可执行以下命令升级：

npm install ng-packagr@latest --save-dev
