这是我的 pubspec.YAML 文件。 我已经安装了颤振并尝试在 iPhone 上运行现有的颤振项目。 当我尝试运行颤振时，我得到了这个错误。 我尝试寻找解决方案，但找不到。谁能告诉我需要做什么？

Answer 1

我在pub找不到fluttery包

可能被删除了。选择fluttery_dart2。

Answer 2

发生这种情况是因为颤振以这种方式配置 podfile。 Flutter 默认生成的 podfile 不允许 ios build 下载嵌套的依赖项。 要解决此问题，您可以通过此更改 podfile 文件，您的问题将得到解决。 搜索这段代码

target 'Runner' do
  # Flutter Pod

用下面的替换它

target 'Runner' do
  use_frameworks!
  # Flutter Pod

更新

由于 Flutter 升级，Fluttery 包被移除/暂时关闭。所以你应该用

更新你的 pubspec.yaml 文件

fluttery_dart2: ^0.0.9

库使用相同的功能。好吧，一旦原来的图书馆回来了，这个图书馆就不会很长时间了。
