我该如何解决这个错误？我只想开发 Android 应用程序。但是当我运行时react-native start我收到此错误-

\n

错误：react-native-permissions：NativeModule.RNPermissions 为空。要解决此问题，请尝试以下步骤：\n\xe2\x80\xa2 如果您在 iOS 上使用 CocoaPods，请pod install在ios目录中运行，然后清理、重建并重新运行应用程序。您可能还需要重新打开 Xcode 才能获取新的 pod。

我可以暂时跳过 ios 部分并仅构建 Android 应用程序吗？或者如何解决 pod 安装错误？请帮忙！

Answer 1

就我而言，安装的 sed 版本是问题所在。React Native 假定 macos 上默认安装了 sed，它能够处理以下表达式：

sed -i '' 's/\@ac_cv_have_libgflags\@/0/' src/glog/logging.h.in

在我的 CI 系统上，我安装了 gnu-sed，这导致了上述错误。

检查您的系统并确保sed指向默认的 Macos 安装 ( /usr/bin/sed)。如果您需要 gnu-sed 用于其他脚本（在我的例子中，我需要在版本控制脚本中使用 gnu-sed 特定语法），您可以将其与 brew 并排安装：

brew install gnu-sed

您可以使用 来调用 gnu-sed gsed。
