NET core 添加了新的nuget包，部署出現Could not load file or assembly

這個坑，今天整了一天，我添加了Microsoft.AspNetCore.Mvc.Versioning包，結果發布到服務器，我復制了dll過去出現了一直找不到加載不成功的問題

 

Startup.ConfigureServices一直加載不成功，出錯如下:

Application startup exception: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.AspNetCore.Mvc.Versioning, Version=2.2.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. 系統找不到指定的文件。
File name: 'Microsoft.AspNetCore.Mvc.Versioning, Version=2.2.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'
at SC.API.Startup.ConfigureServices(IServiceCollection services)
--- End of stack trace from previous location where exception was thrown ---
at Microsoft.AspNetCore.Hosting.ConventionBasedStartup.ConfigureServices(IServiceCollection services)
at Microsoft.AspNetCore.Hosting.Internal.WebHost.EnsureApplicationServices()
at Microsoft.AspNetCore.Hosting.Internal.WebHost.Initialize()
--- End of stack trace from previous location where exception was thrown ---
at Microsoft.AspNetCore.Hosting.Internal.WebHost.BuildApplication()

 

后面仔細發現，添加了新的nuget包，發布后，在發布地址的目錄下 找到這個文件

 

 

*.deps.json 此文件會新增nuget包的依賴關系，比較后發現

 

 

 

解決方法:除業務DLL以外，還需要復制此json文件覆蓋，使得項目可以加載nuget包，不然netcore 無法映射加載新的包
