我已经为我的React Native应用程序创建了一个临时配置，作为我的Release版本的克隆。但是，当我运行react-native run-ios --configuration Staging时，我的构建失败了：
Installing build/Build/Products/Staging-iphonesimulator/flockCover.app
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/Staging-iphonesimulator/myApp.app/Info.plist
Print: Entry, ":CFBundleIdentifier", Does Not Exist
检查构建后，似乎出现了一些问题： 1）CodeSign在Release版本上运行如下：
CodeSign build/Build/Products/Release-iphonesimulator
2）从版本构建生成符号：
GenerateDSYMFile build/Build/Products/Release-iphonesimulator/flockCover.app/PlugIns/flockCoverTests.xctest.dSYM build/Build/Products/Release-iphonesimulator
其他各种事情都指向Release。
进一步检查表明这是因为我的（构建）环境变量设置不正确，例如：
export BUILT_PRODUCTS_DIR=/Users/name/github/company/app/ios/build/Build/Products/Release-iphonesimulator
export CODESIGNING_FOLDER_PATH=//Users/name/github/company/app/ios/build/Build/Products/Release-iphonesimulator/flockCover.app
export CONFIGURATION=Staging
export CONFIGURATION_BUILD_DIR=/Users/name/github/company/app/ios/build/Build/Products/Release-iphonesimulator
export CONFIGURATION_TEMP_DIR=/Users/name/github/company/app/ios/build/Build/Intermediates/ReactNativeConfig.build/Staging-iphonesimulator
此外，所有第三方库（例如React-Native，Yoga）都在发布模式下运行，结果如下：
export CLASS_FILE_DIR==/Users/name/github/company/app/ios/build/Build/Intermediates/ReactNativeConfig.build/Release-iphonesimulator/ReactNativeConfig.build/JavaClasses
一个有趣的说明，并非所有事情都指向Release，除了最终的错误信息之外，还有以下内容：
=== BUILD TARGET myApp OF PROJECT myProject WITH CONFIGURATION Staging ===
Ld build/Build/Intermediates/flockCover.build/Staging-iphonesimulator（更不用说上面的CONFIGURATION环境变量。
所以我的问题如下：
1）如何正确设置这些环境变量（具体为CODESIGNING_FOLDER_PATH，CONFIGURATION_BUILD_DIR等。
2）如何在依赖库中构建一个与我的应用程序配置不同的依赖库（例如React）。我是否还需要在那里创建配置？
3）这首先是导致我的问题的原因吗？
