如果在使用Babel时遇到类继承无法正确转译的问题，可以尝试使用@babel/plugin-proposal-class-properties插件。该插件可以正确地将类继承转译为ES5兼容的代码。

示例代码：

// 安装@babel/plugin-proposal-class-properties
npm install --save-dev @babel/plugin-proposal-class-properties

// babel.config.js中添加插件配置
module.exports = {
  "plugins": [
    ["@babel/plugin-proposal-class-properties", { "loose": true }]
  ]
}

// 示例代码
class Animal {
  constructor(name) {
    this.name = name;
  }

  getName() {
    return this.name;
  }
}

class Dog extends Animal {
  constructor(name) {
    super(name);
  }

  bark() {
    console.log("Dog " + this.getName() + " is barking.");
  }
}

const dog = new Dog("Snoopy");
dog.bark(); // Output: Dog Snoopy is barking.
