D：\ Alief \ Kelas-12 \ KK4-B \ react_native_crud>本机启动错误

下面是运行上述命令后出现的错误

class Program
{
    static void Main(string[] args)
    {
        Student student = new Student
        {
            //informatie over de studen
            Studentnummer = "S101010",
            Naam = "Voornaam Achternaam",
            Postcode = "1111AT",
            Telefoonnummer = "31+ 0571 123456"
        };
        student.Wakken.Add("Voorbeeld vak 1");
        student.Wakken.Add("Voorbeeld vak 2");

        Console.WriteLine(student.ToString());
    }
}

class Student
{
    //alle properties van de student
    public string Studentnummer { get; set; }
    public string Naam { get; set; }
    public string Postcode { get; set; }
    public string Telefoonnummer { get; set; }
    public List<string> Wakken { get; } = new List<string>();

    //een no-argument constructor
    public Student()
    { }
    //override van de ToString methode? (ik weet niet of dit ook de goede manier is)
    public override string ToString()
    {
        return $"Studentnummer: {Studentnummer}, naam: {Naam}, postcode: {Postcode}, telefoonnummer :{Telefoonnummer}, aantal vakken: {String.Join(", ", Wakken)}";
    }

}

Answer 1

您是否尝试安装依赖项Metro-resolver？

在您的本机项目文件夹中打开cmd并运行命令

npm i metro-resolver和npm install。

如果使用纱线， yarn install metro-resolver 和 yarn install

npm i metro-resolver将安装“ metro-resolver”，而npm install将安装package.json

中提到的所有必需依赖项

键入react-native启动命令``找不到模块''Metro-Resolver''时遇到一些问题
