我有这个问题。我建议你审查你的巴贝尔案。

我的原信巴贝尔。

// babel.config.js
module.exports = function(api) {
  api.cache(true);
  return {
    presets: [
       babel-preset-expo ,
       @babel/preset-env ,
       @babel/preset-react ,
      //  @babel/preset-typescript , // Uncomment if using TypeScript
    ],
    plugins: [
      ["@babel/plugin-proposal-class-properties", { "loose": true }],
      ["@babel/plugin-transform-private-methods", { "loose": true }],
      ["@babel/plugin-transform-private-property-in-object", { "loose": true }],
       react-native-reanimated/plugin ,
    ],
  };
};

把这个问题改成下文似乎确定了问题:

// babel.config.js
module.exports = function(api) {
  api.cache(true);
  return {
    presets: [ babel-preset-expo ],
    plugins: [
      // Ensure  react-native-reanimated/plugin  is last
       react-native-reanimated/plugin ,
    ],
  };
};
