（与 https://stackoverflow.com/questions/76296732/installed-react-native-image-picker-getting-typeerror-null-is-not-an-object?noredirect=1#comment134543272_76296732 一起发布，因为我不确定这两者是否有不同的根本原因。）
我正在尝试在我的 Expo RN 应用程序中使图像选择器正常工作。我的 package.json 包括以下内容：
"expo": "~48.0.15",
"expo-image-picker": "^14.1.1",
"react": "18.2.0",
"react-native": "0.71.8",
到目前为止，我对此的实现相对简单：
import * as ImagePicker from 'expo-image-picker';
...
const handleChoosePhoto = async () => {
let result = await ImagePicker.launchImageLibraryAsync({
mediaTypes: ImagePicker.MediaTypeOptions.All,
allowsEditing: true,
aspect: [4, 3],
quality: 1,
});
console.log(result);
}
[稍后，有一个 TouchableOpacity，调用 handleChoosePhoto onPress]
这是根据 [Expo 的文档][1] 进行的。
当我尝试这个时，我收到了以下错误：
WARN Possible Unhandled Promise Rejection (id: 0):
TypeError: undefined is not an object (evaluating '_ExponentImagePicker.default.launchImageLibraryAsync')
我在 Expo 开发构建上尝试了这个。我尝试过更新 react-native（从 0.70.5 到现在的 0.71.8）和 expo（从 47 到 48）。我还在安装 react-native-image-picker 后执行了 npx pod-install。
我还刚刚修改了我的 `metro.config.js`，遵循了 [这个建议的解决方法][2]，因为我遇到了 - 我认为与此无关 - 指向 `DatePickerIOS` 的错误。
有关出现问题的任何提示吗？

I'm trying to get an image picker working in my Expo RN app. My package.json includes these:
"expo": "~48.0.15",
"expo-image-picker": "^14.1.1",
"react": "18.2.0",
"react-native": "0.71.8",
My implementation of this so far is relatively simple:
import * as ImagePicker from 'expo-image-picker';
...
const handleChoosePhoto = async () => {
let result = await ImagePicker.launchImageLibraryAsync({
mediaTypes: ImagePicker.MediaTypeOptions.All,
allowsEditing: true,
aspect: [4, 3],
quality: 1,
});
console.log(result);
}
[Later on, there's a TouchableOpacity that calls handleChoosePhoto onPress]
This is following Expo's documentation
When I try this out, I get the error:
WARN Possible Unhandled Promise Rejection (id: 0):
TypeError: undefined is not an object (evaluating '_ExponentImagePicker.default.launchImageLibraryAsync')
I'm trying this on an Expo development build. I've tried updating react-native (was on 0.70.5, now on 0.71.8) and expo (from 47 to 48). I've also done an npx pod-install after installing react-native-image-picker.
I also just modified my metro.config.js following this suggested workaround because I was getting the - I believe unrelated - error pointing to DatePickerIOS.
Any tips on what's wrong?

我有同样的问题，如果我记得正确，我只需要重新构建我的应用程序然后再次发布它。

I had the same issue and if I remember correctly all I had to do was rebuilding my app and publishing it again.
