无法安装 FlutterFire CLI

Question

https://firebase.google.com/codelabs/firebase-get-to-know-flutter#3

\n

dart pub global activate flutterfire_cli\n

\n

我按照上页的说明执行了上述命令。\n执行此操作时，我收到以下错误消息。

\n

The current Dart SDK version is 2.10.5.\n\nBecause pub global activate depends on flutterfire_cli any which requires SDK version >=2.12.0 <3.0.0, version solving failed.\n

\n

当我运行 flutter Upgrade 进行尝试时，我收到以下消息。

\n

Flutter is already up to date on channel stable\nFlutter 2.8.1 \xe2\x80\xa2 channel stable \xe2\x80\xa2 https://github.com/flutter/flutter.git\nFramework \xe2\x80\xa2 revision 77d935af4d (5 weeks ago) \xe2\x80\xa2 2021-12-16 08:37:33 -0800\nEngine \xe2\x80\xa2 revision 890a5fca2e\nTools \xe2\x80\xa2 Dart 2.15.1\n

\n

dart pub 全局激活 flutterfire_cli

\n

然后我再次运行上面的命令，但仍然收到相同的错误消息。

\n

我应该怎么办？

Answer 1

看来您安装了 Dart SDK 2.10.5 版本，与 flutter 附带的版本（Dart v2.15.1）分开。使用此命令升级 Dart SDK

（苹果系统）

brew upgrade dart

（视窗）

choco upgrade dart-sdk

(Linux)

sudo apt-get install dart
