按官方文档创建Flutter项目遇flutter_lints授权失败问题求助

问题详情 #

按照Flutter官方Windows安装流程创建默认项目时，执行flutter packages get或flutter update始终触发如下错误：

flutter_lints any which doesn't exist (authorization failed), version solving failed

flutter doctor检测结果全部正常，尝试更换Flutter SDK版本、修改pubspec.yaml中flutter_lints依赖写法（直接改为flutter_lints:）均无法解决问题。

项目默认配置文件如下：

pubspec.yaml #

name: untitled7
description: "A new Flutter project."

publish_to: 'none' 

version: 1.0.0+1

environment:
  sdk: '>=3.3.3 <4.0.0'

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: ^1.0.6

dev_dependencies:
  flutter_test:
    sdk: flutter

  flutter_lints: ^3.0.1

flutter:
  uses-material-design: true

analysis_options.yaml #

include: package:flutter_lints/flutter.yaml

linter:

解决方案 #

• 切换并清理Pub源
  国内环境优先使用国内镜像源，执行命令：

  flutter config --set pub-hosted-url https://pub.flutter-io.cn
  flutter config --set storage-base-url https://storage.flutter-io.cn
  

  随后清除本地Pub缓存并重新拉取依赖：

  flutter pub cache clean
  flutter pub get
  

• 排查网络与权限问题

  1. 若使用代理，确认代理规则允许访问Pub源地址，或直接关闭代理后重试flutter pub get
  2. 检查当前用户对Flutter SDK目录、项目目录是否拥有完整读写权限，权限不足会导致缓存文件无法正常下载或读取

• 手动安装flutter_lints包

  1. 获取对应版本的flutter_lints源码包
  2. 解压后将文件夹重命名为flutter_lints，放置到Flutter SDK目录下的/.pub-cache/hosted/[你的Pub源域名]/路径中（比如国内源对应路径为/.pub-cache/hosted/pub.flutter-io.cn/）
  3. 返回项目根目录执行flutter pub get

• 重置Flutter配置
  执行命令重置所有Flutter配置，再重新拉取依赖：

  flutter config --clear
  flutter pub get
