问题描述
我在 Linux 上使用 JetBrains Rider。每当我运行 //--- style ----//
.mapBoxgl-ctrl-geocoder {
font-size: 18px;
line-height: 24px;
font-family: "Open Sans","Helvetica Neue",Arial,Helvetica,sans-serif;
position: relative;
background-color: #fff;
width: 100%;
min-width: 240px;
z-index: 1;
border-radius: 4px;
transition: width .25s,min-width .25s;
right: 900px;
visibility: hidden;
}
.mapBoxgl-ctrl-geocoder .show {
visibility: visible;
}
//----- javascript code ------//
function search() {
let el_mapBoxgl = document.getElementsByClassName('mapBoxgl-ctrl-geocoder')[0];
el_mapBoxgl.className += " show";
}
时,它都会在终端中执行此操作并给我以下错误:
dotnet ef migrations add InitialCreate
如果有人知道答案,谢谢!
解决方法
我在 .net 5 Web API 项目中遇到了同样的问题
EF 工具查看 CreateWebHostBuilder 方法并在找不到时返回错误。
directories:
/src
|-- /YourPorject.Infrastructure
|-- /YourPorject.API
public static IHostBuilder CreateWebHostBuilder(string[] args)
{
return Host.CreateDefaultBuilder(args)
.ConfigureAppConfiguration((context,config) =>
{
config.AddJsonFile(
context.HostingEnvironment.ContentRootPath + $"/Config/appsettings-dev.json",false,false);
})
.ConfigureWebHostDefaults(webBuilder => { webBuilder.UseStartup<Startup>(); });
}
使用bash创建和更新数据库
cd src/
dotnet ef migrations add Init
--project YourPorject.Infrastructure/YourPorject.Infrastructure.csproj
--startup-project YourPorject.API/YourPorject.API.csproj
-o ./Repositories/Migrations/
cd src/
dotnet ef database update
--project YourPorject.Infrastructure/YourPorject.Infrastructure.csproj
--startup-project YourPorject.API/YourPorject.API.csproj
使用这个包(很重要)
