错误:components/Alphabet.js:第 51 行的调用无效:需要(来源)
并尝试require(soundPathVar)从getState()方法返回对象并从 中删除 required play(),然后出现相同的错误。
我是 react-native 的初学者,我想尝试创建一个动态声音文件路径。所以如果我做错了,你能帮助我吗?预先感谢。
我在尝试require动态图像时遇到了这个问题,结果require只接受特定来源甚至require("SOURCE/" + "something.png")不起作用,它应该是require("SOURCE/something.png"). 尝试这个:
export default class alphService {
stateObj = {
sound: ""
};
getState(){
this.stateObj.sound = require("../assets/sounds/c.mp3");
return this.stateObj;
}
}

您可以创建一个包含所有路径的 json 文件并像这样使用它:
export default const paths = {
file1: require("path/to/file1.png"),
file2: require("path/to/file2.png")
}

然后在您的组件中导入此路径文件并像这样使用它(例如图像):
<Image source={paths.file1}/>
