flutter pub run build_runner 卡住了

Question

我在運行時遇到問題

flutter pub run build_runner build --delete-conflicting-outputs

該命令沒有出錯，但它卡在第一個文件上：

WARNING] No actions completed for 15.0s, waiting on:
  - auto_route_generator:autoRouteGenerator on lib/ui/shared/ui_helpers.dart
  - auto_route_generator:autoRouteGenerator on lib/ui/views/settings/settings_datamodel.dart
  - auto_route_generator:autoRouteGenerator on lib/ui/views/settings/settings.dart
  - auto_route_generator:autoRouteGenerator on lib/ui/views/review_invitation/review_invitation_datamodel.dart
  - auto_route_generator:autoRouteGenerator on lib/ui/views/review_invitation/review_invitation.dart
  .. and 9 more

[INFO] 1m 17s elapsed, 1/15 actions completed.

以下是我的 pubspec：

dependencies:
  flutter:
    sdk: flutter

  # see below for explanation
  stacked_services:
  auto_route:
  stacked: ^1.7.6
  stacked_hooks: 0.1.1+3
  flutter_hooks:
  get_it:
  injectable:
  validators: ^2.0.0 

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.3

dev_dependencies:
  flutter_test:
    sdk: flutter

  build_runner:
  auto_route_generator:
  injectable_generator:

雖然這是我的 router.dart 課程

import 'package:auto_route/auto_route_annotations.dart';
import 'package:myapp/ui/views/StartupView.dart';

@MaterialAutoRouter(
  routes: <AutoRoute>[
    MaterialRoute(page: StartupView, initial: true),
  ],
)
class $Router {}

有什么建議嗎？

Answer 1

flutter pub upgrade解決了我的問題。

Answer 2

方法 1：如果在升級 flutter后發生此問題，請嘗試運行：

flutter packages upgrade然后flutter pub run build_runner build

---

方法2：這為我解決了：

1- flutter clean

2- 刪除所有 *.g.dart 如果存在

3- 進入開發頻道： flutter channel dev

4-升級： flutter upgrade --force

5- flutter pub get

6- 嘗試構建： flutter pub run build_runner build

7- 回到穩定或主通道： flutter channel stable （ flutter channel master ）

8-升級： flutter upgrade --force

---

Answer 3

如果有人遇到同樣的問題，請嘗試將 flutter 從 v1.20.1 升級到 v1.20.2

Answer 4

確保您的項目名稱不包含“%20”個字符。 這會導致任何構建方法，例如flutter packages pub run build_runner build --delete-conflicting-outputs和flutter pub run build_runner clean失敗。
