执行dart run build_runner build命令时出现路径不存在错误

执行dart run build_runner build（添加--delete-conflicting-outputs参数后仍报错）时触发以下错误：

PathNotFoundException: Cannot open file, path = 
'.dart_tool/build/entrypoint/build.dart.dill.cached' (OS Error: No such file or directory, errno = 2)
#0      _checkForErrorResponse (dart:io/common.dart:55)
#1      _File.open.<anonymous closure> (dart:io/file_impl.dart:381)
<asynchronous suspension>
#2      _FileStreamConsumer.addStream.<anonymous closure> (dart:io/file_impl.dart:205)
<asynchronous suspension>

环境信息 #

• Flutter版本：3.19.5
• flutter doctor输出：

No issues found!

解决方案 #

• 清理.dart_tool目录：

  1. 项目根目录执行对应系统命令：
     • Mac/Linux：rm -rf .dart_tool
     • Windows：rd /s /q .dart_tool
  2. 执行flutter pub get重新拉取依赖
  3. 再次运行dart run build_runner build

• 如果上述方法无效，尝试全量清理：

  1. 执行flutter clean
  2. 执行flutter pub get
  3. 重新执行build_runner命令
