无法在项目“Runner.xcodeproj”中找到名为“Runner”的目标，但确实找到了“dev”和“prod”

Question

我对 Flutter 完全陌生。

\n

我收到了一个几个月前（2020 年 12 月）在 Visual Studio Code 上使用 Flutter 和 Dart 开发的项目，以便将其部署到 App \xc2\xa0Store上。

\n

我想指出的是，当时该项目运行得非常好，甚至在 iPhone 上部署了测试版本。

\n

我必须确保它可以在本地运行，然后我将其部署到 App\xc2\xa0Store。

\n

所以我在我的 Visual Studio Code 中打开了该项目的源代码。我尝试编译它，但没有成功。我不知道当你打开一个项目的源代码时；有一些具体的配置要做。

\n

我不确定在打开项目源代码时是否需要进行任何具体配置，但是在浏览论坛后，我意识到该错误一定来自我的 Flutter 的最新版本，并且不是应用程序开发时使用的版本。

\n

因此，我按照Flutter iOS build failed an error of pod files: Podfile is out of date和Flutter error: Invalid `Podfile` file: noimplicit conversion of nil into String 中此解决方案的说明进行操作。我\xe2\x80\x99已经搜索了讨论，但我可以\xe2\x80\x99t似乎解决了问题以再次生成我的podfiles。只是现在这个错误是在编译时生成的：

\n

Launching lib/main.dart on iPhone 8 in debug mode...\nRunning pod install...                                           1,674ms\nCocoaPods\' output:\n\xe2\x86\xb3\n      Preparing\n\n    Analyzing dependencies\n\n    Inspecting targets to integrate\n    [!] Unable to find a target named `Runner` in project `Runner.xcodeproj`, did\n    find `dev` and `prod`.\n

\n

我怎样才能解决这个问题？

我之前的 pod 文件是

实际上，当我跑步时flutter doctor，我得到：

\n

实际上在 Xcode 中打开我的项目会得到以下结果：

Answer 1

这是一种错误。RunnerTests 应该手动添加。但不知何故该命令自动添加了它。可以参考iOS设备测试中的RunnerTests

但要解决这个问题，请打开Podfile并注释这些行：

  # target 'RunnerTests' do
  #   inherit! :search_paths
  # end

Answer 2

我遇到了这个问题。

无法找到Runner Tests项目中指定的目标Runner.xcodeproj

我必须删除我的 ios 文件夹 ( Not recommended if you have done any changes to native IOS code)，然后使用此命令重新创建它。

如果您对文件夹进行了任何更改IOS，请尝试此命令，而无需删除该ios目录。这应该会生成缺失的元素。

flutter create --platform ios .

可能的原因

我在 .NET 以外的操作系统上创建的项目中注意到了这个问题mac。

Answer 3

我假设您以前使用过 Flutter 1.X。

这是我最近下载 Flutter v2.0.4 时所做的：

1. 当我第一次打开旧项目时，Visual Studio Code 将显示我的所有文件都包含错误。所以我要做的就是跑步flutter pub get。这将消除错误。

2. 接下来我尝试在 iOS 模拟器中以调试模式运行。之后，我ios使用 Xcode 打开（项目内部）文件夹，单击“targets”下的Runner并检查签名，然后再在 iPhone 上进行测试。

因此，就您的情况而言，请放弃您最近所做的任何更改，或者如果您首先需要它，则将其存储在 Git 中。并flutter pub get在模拟器上运行并测试它。这应该可以解决问题，他们会应用/弹出您的藏品，现在您就可以走了。

另请注意，每当您跑步时flutter clean，您都必须flutter pub get再次跑步。否则，您将看到 Visual Studio Code 将以红色显示库文件夹中的所有文件。

flutter clean如果flutter pub get不能正确完成工作，请运行此命令：

flutter clean
flutter pub get
cd ios
rm Podfile
pod setup
flutter build ios
