Flutter // 警告：使用多个匹配目标中的第一个

问题描述 投票：0回答：2

我正在使用 Flutter 开发移动应用程序。

当我在 iOS 物理设备上运行该应用程序时...我不断收到此错误，因此我无法在我的设备上运行我的应用程序。

当我在 Android 设备上运行它时没有问题，，，，，但只有 iOS 设备，，我得到这个....

我坚持了几天，我无法弄清楚。

我需要你的帮助，请帮助我。

尝试一下

terminal

 1. sudo gem update cocoapods --pre
 2. pod update

并且在 

Xcode

 3. clean
 4. build

如果无法修复，请尝试更改步骤 2，如

  • 删除 
    Pod
    文件夹和 
    Podfile.lock
  • cd
    到项目目录，然后运行
    pod install

我之前尝试过它的工作原理，我不确定它是否适合你的情况

我找到了另一种方法：

  1. 删除
    Pods
    整个文件夹、
    Podfile.lock
    和另外一个文件
    $project.xcworkspace
  2. 奔跑
    pod deintegrate
  3. 奔跑
    pod install

我已经奋斗了一个星期，尝试了 Stack Overflow 上写的所有内容，但总是失败。我删除了 Xcode 应用程序并重新创建了它，我的项目成功了。
