我检查了react-native/packages/react-native/ReactCommon/jsi/React-jsi.podspec文件，发现了这些行：

if js_engine == :jsc
    s.source_files  = "**/*.{cpp,h}"
    s.exclude_files = [
                        "jsi/jsilib-posix.cpp",
                        "jsi/jsilib-windows.cpp",
                        "**/test/*"
                      ]

  elsif js_engine == :hermes
    # JSI is provided by hermes-engine when Hermes is enabled
    # Just need to provide JSIDynamic in this case.
    s.source_files = "jsi/JSIDynamic.{cpp,h}"
    s.dependency "hermes-engine"
  end
end

找不到文件jsi.h，因为js_engine已设置为:hermes。
我把它切换到:jsc，它帮助。
以下是如何在Podfile中执行此操作：
1.将iOS版本更改为至少13：

platform :ios, '13.0'

1.调用use_react_native时禁用爱马仕：

use_react_native!(
    :path => "../node_modules/react-native",
    :hermes_enabled => false,
    # ...

这帮了我。
