这是我的终端输出： 我试图更新Xcode，但仍然出现相同的错误。当我运行flutter -doctor v时，它会通过所有情况，并且在每个部分中都有一个选中标记。我尝试使用AndroidStudio进行构建，然后从终端进行构建，在两种情况下都遇到了相同的错误。使用Nexus 6 API构建的AndroidStudio运行良好，只是遇到了iOS构建方面的麻烦

编辑： 我找到了一种使它暂时工作的方法。我打开Xcode并在其中构建它，然后运行Simulator，然后关闭Xcode并安装Simulator并使用VSCode构建我的应用程序。但是我该如何解决终端命令错误？
答案 0 :(得分：0)
我有一个类似的问题（不同的错误，但都是关于进口的。）
我最终通过将cocoapods和cocoapods-core从版本1.9.3升级到1.10来解决了这个问题。
希望这可以帮助其他面临相同问题的人。
