CocoaPods 已安装但再次显示错误消息未安装

Question

我是 flutter 的新手，我买了一台新的 MacBook Pro BigSur 并尝试安装 flutter。我遇到了 CocoaPods 的问题，我做了所有事情，最后我成功安装了，正如你在我的 flutter doctor 中看到的那样。但是现在的问题是，当我运行模拟器时，我得到同样的消息错误，CocoaPods 未安装或无效状态....我不明白这种情况，我现在该怎么办？

请帮帮我....

这里是我的颤振医生..

Answer 1

尝试：sudo arch -x86_64 gem 安装 ffi
然后运行: arch -x86_64 pod install

您还需要更新 iOS 文件夹中的播客文件，取消注释第二行并将“9.0”替换为“10.0”

应该可以。

如果您使用的是 Android Studio，这是用户在刚刚发布的新版“Bumblebee”2021.1.1 中遇到的问题。

目前的解决方法是使用如下命令行启动 Android Studio：

open /Applications/Android\ Studio.app

Answer 3

export PATH="/usr/local/lib/ruby/gems/3.0.0/bin:$PATH"

设置最新版本 Ruby 的路径，然后直接从 cmd 打开应用程序 line/terminal 为我修复了它。

open /Applications/Android\ Studio.app
