打印：输入，＆＃34;：CFBundleIdentifier＆＃34;，不存在已尝试过大多数解决方案

Question

我几乎尝试了所有的解决方案，但似乎没有一种解决方案。

An error was encountered processing the command   (domain=NSPOSIXErrorDomain,   code=2):
Failed to install the requested application
An application bundle was not found at the provided path.
Provide a valid path to the desired application bundle.
Print: Entry, ":CFBundleIdentifier", Does Not Exist

Command failed: /usr/libexec/PlistBuddy -c Print:CFBundleIdentifier     build/Build/Products/Debug-iphonesimulator/albums.app/Info.plis      

打印：输入，＆＃34;：CFBundleIdentifier＆＃34;，不存在

如何让项目运行？

Answer 1

由于我删除了一些我不会在Xcode中使用的模拟器，我的终端弹出相同的信息。

如果您运行react-native run-ios没有特定参数，react-native将运行默认模拟器，即我的情况下带有iOS 10.3.1的iPhone 6，我偶然删除了这个模拟器。

这是我的错误消息：

xcodebuild: error: Unable to find a destination matching the provided destination specifier:
        { id:F3A7BF54-B827-4517-A30D-8B3241C8EBF8 }

Available destinations for the "albums" scheme:
    { platform:iOS Simulator, id:CD64F26B-045A-4E27-B05A-5255924095FB, OS:10.3.1, name:iPad Pro (9.7 inch) }
    { platform:iOS Simulator, id:8FC41950-9E60-4264-B8B6-20E62FAB3BD0, OS:10.3.1, name:iPad Pro (10.5-inch) }
    { platform:iOS Simulator, id:991C8B5F-49E2-4BB7-BBB6-2F5D1776F8D2, OS:10.3.1, name:iPad Pro (12.9 inch) }
    { platform:iOS Simulator, id:B9A80D04-E43F-43E3-9CA5-21137F7C673D, OS:10.3.1, name:iPhone 7 }
    { platform:iOS Simulator, id:58F6514E-185B-4B12-9336-B8A1D4E901F8, OS:10.3.1, name:iPhone 7 Plus }

。 。

Installing build/Build/Products/Debug-iphonesimulator/myapp.app
An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=2):
Failed to install the requested application

为了摆脱这些，打开Xcode并检查可用的模拟器（与列出的终端相同）并运行react-native run-ios --simulator="your device name"

对于我的情况，我运行react-native run-ios --simulator="iPhone 7"，问题解决了。

Answer 2

对我有用的是在xcode中打开项目并在那里运行项目。 Xcode对我来说有一些问题。第一个问题是我选择了错误的设备进行测试。

我确保选择了iPhone X模拟器（由于某种原因，它默认设置为未设置为开发设备的ipad）。

然后确保在运行时没有红色警告。我还有一个红色警告，那是因为我没有选择项目的团队资料。

我还将捆绑包标识符更改为我的公司名称，以使其唯一。

在xcode中运行它是了解错误的最佳方法。不要单靠反应本机来找出错误。

Answer 3

当我删除~/.rncash

时，它对我有用
