连接超时：连接？

Question

我只安装android studio 3.1.3

我无法同步“连接超时：连接”的gradle原因

关于如何删除它的任何想法？

顶级构建文件，您可以在其中添加所有子项目/模块共有的配置选项。

buildscript {

task clean(type: Delete) {
 delete rootProject.buildDir

}

import React from 'react';

export const MenuContext = React.createContext();

class MenuProvider extends React.Component {
  state = {
    menu: {}
  };
  actions = {
    fetchMenu: async() => {
      const response = await fetch('/admin/json/menu.json');
      const body = await response.json();
      this.setState({
        menu: body
      });
    }
  }
  componentDidMount() {
    this.actions.fetchMenu();
  }
  render() {
    return(
      <MenuContext.Provider value={{state: this.state, actions: this.actions}}>
        {this.props.children}
      </MenuContext.Provider>
    )
  }
}

export default MenuProvider;

}
