typedef redefinition with different types ('uint8_t' (aka 'unsigned char') vs 'enum clockid_t')。在Github上有一些提议的解决方法，但是没有一个能够解决我的问题。https://github.com/facebook/flipper/issues/834。是否有人找到了解决方法？非常感谢。 # use_flipper!
# post_install do |installer|
# flipper_post_install(installer)
# end
步骤1：
进入YOUR_PROJECT > ios > Podfile，然后注释掉以下几行代码：
# use_flipper!()
# post_install do |installer|
# react_native_post_install(installer)
# __apply_Xcode_12_5_M1_post_install_workaround(installer)
# end
步骤2：
在完成步骤1后，您需要在YOUR_PROJECT > ios路径下运行 pod update 命令。
Bingo就完成了。
重要提示：
如果您在完成上述两个步骤后遇到一些错误，请执行以下步骤：
YOUR_PROJECT > ios > YOUR_PROJECT_NAME >并运行以下命令plutil ./Info.plist它将向您显示问题所在位置。react_native_post_install(installer)部分。 - xji项目所在的目录名称不应包含空格。否则会导致此错误。
这是我针对React Native 0.65的解决方法。非常重要的是，folly 应链接到 9.0 版本。
post_install do |installer|
react_native_post_install(installer)
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings.delete "IPHONEOS_DEPLOYMENT_TARGET"
end
case target.name
when 'RCT-Folly'
target.build_configurations.each do |config|
config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
end
end
end
end
首先，从您的项目中删除Flipper。
接下来，按照以下路径进行操作： 路径："Your-Project-App/ios/Pods/RCT-Folly/folly/portability/Time.h"
将该代码替换为time.h。

#endif在这之后，请尝试通过Xcode运行应用程序，现在该应用程序无法成功运行，您会得到另一个错误。
第二个错误是："Command PhaseScriptExecution failed with a nonzero exit code"。
第二个错误的解决方法如截图所示：
请使用以下代码更新你的Pod文件。
use_flipper!({ 'Flipper-Folly' => '2.3.0' }) # update this part
post_install do |installer|
flipper_post_install(installer)
end
对我来说，这个错误是因为我在 ios/Podfile 中做了以下操作：
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
end
end
installer.pods_project.build_configurations.each do |config|
config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
end
我只能假设将 "Folly" 目标的构建目标设置弄错了什么。一旦这些行从我的 Podfile 中删除，并运行 npx pod-install，构建就又可以正常工作了。
我需要指定版本：
# https://github.com/facebook/flipper/releases
# https://cocoapods.org/pods/Flipper-Folly
# https://cocoapods.org/pods/OpenSSL-Universal
use_flipper!({
"Flipper" => "0.134.0",
"Flipper-Folly" => "2.6.10",
"OpenSSL-Universal" => "1.1.1100"
})
对于完整的Podfile，这可能会有所帮助：
require_relative "../node_modules/expo/scripts/autolinking"
require_relative "../node_modules/react-native/scripts/react_native_pods"
require_relative "../node_modules/@react-native-community/cli-platform-ios/native_modules"
platform :ios, "12.0"
target "socializus" do
use_expo_modules!
config = use_native_modules!
use_react_native!(
path: config[:reactNativePath],
hermes_enabled: false
)
# https://github.com/facebook/flipper/releases
# https://cocoapods.org/pods/Flipper-Folly
# https://cocoapods.org/pods/OpenSSL-Universal
use_flipper!({
"Flipper" => "0.134.0",
"Flipper-Folly" => "2.6.10",
"OpenSSL-Universal" => "1.1.1100"
})
post_install do |installer|
flipper_post_install(installer)
react_native_post_install(installer)
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings.delete "IPHONEOS_DEPLOYMENT_TARGET"
end
end
end
end
我曾遇到与 RCT-Folly 相关的问题，并通过以下方法解决了它:
基本上，问题出在文件 ../node_modules/react-native/scripts/react_native_pods.rb 中。这是该文件的代码。
# But... doing so caused another issue in Flipper:
# "Time.h:52:17: error: typedef redefinition with different types"
# We need to make a patch to RCT-Folly - remove the `__IPHONE_OS_VERSION_MIN_REQUIRED` check.
# See https://github.com/facebook/flipper/issues/834 for more details.
time_header = "#{Pod::Config.instance.installation_root.to_s}/Pods/RCT-Folly/folly/portability/Time.h"
`sed -i -e $'s/ && (__IPHONE_OS_VERSION_MIN_REQUIRED < __IPHONE_10_0)//' #{time_header}`
node_modules中的代码，.lock文件将会被更改。因此为了安全起见，你可以更新Podfile。Podfile的post_install do |installer|行后添加以下代码段，如下所示：
添加以下代码行
sed -i -e $'s/__IPHONE_10_0/__IPHONE_12_0/' Pods/RCT-Folly/folly/portability/Time.h
target 'AwesomeProjectTests' do
inherit! :complete
# Pods for testing
end
# Enables Flipper.
#
# Note that if you have use_frameworks! enabled, Flipper will not work and
# you should disable the next line.
use_flipper!()
post_install do |installer|
`sed -i -e $'s/__IPHONE_10_0/__IPHONE_12_0/' Pods/RCT-Folly/folly/portability/Time.h`
react_native_post_install(installer)
__apply_Xcode_12_5_M1_post_install_workaround(installer)
end
end
在项目的根目录下运行 cd ios
在终端中运行 pod deintegrate 命令，然后再使用命令 pod install 重新安装Pod
最后，在项目的根目录下运行命令 npx react-native run-ios 再次构建项目
太棒了！我的问题已经得到了解决。
use_flipper!
post_install do |installer|
flipper_post_install(installer)
