问题描述

当我在 mac book pro 中编译我的项目时，显示此错误：

Xcode's output:

我尝试过这种方式来修复它：

~/apps/flutter/bin/flutter clean

没用，然后我尝试了这种方式：

$ pod install

[!] CocoaPods did not set the base configuration of your project because your project already has a custom config set. In order for CocoaPods integration to work at all, please either set the base configurations of the target `Runner` to `Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig` or include the `Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig` in your build configuration (`Flutter/Release.xcconfig`).

仍然无法正常工作，为什么会发生这种情况，我应该怎么做？这是我的频道：

解决方案

由于您有旧版本的颤振（9 月发布），我建议您将颤振升级到最新的稳定版本，即 1.22.5。只需在终端输入

flutter upgrade

如果这没有帮助，请删除 ios 文件夹，然后输入项目的根目录

flutter create .

重新创建 ios 文件夹并再次尝试构建。
