Question

我安装了软件包using npm，然后按照these instructions (french)对其进行配置以用于iOS。但是我无法使用npx react-native run-ios运行该应用，它给了我这个错误：

xcodebuild: error: Could not resolve package dependencies:
    because no versions of facebook-ios-sdk match the 
    requirement 7.0.2..<8.0.0 and root depends on 
    facebook-ios-sdk 7.0.2..<8.0.0, version solving failed.

我尝试重新安装react-native-fbsdk并再次安装Pod：

$ cd ios
$ rm Podfile.lock
$ pod repo update
$ pod install

另一方面，从xcode运行它没有问题（即使错误仍然出现）。

我的npm环境如下：

{
    "react-native": "0.62.2",
    "react-native-fbsdk": "^2.0.0",
}

我仍然不知道文档中建议的安装发生了什么。但是我们通过更新 facebook-ios-sdk 解决了 Xcode 中的问题： file > Swift packages > Update to latest package versions。

运行后，facebook-ios-sdk 版本出现在 Xcode 中（对我们来说是 7.1.1）。然后错误消失了。
