Visual Studio 2017专业版-无法在源代码中找到包 [英] Visual Studio 2017 Professional- Unable to find package at source

问题描述

我正尝试通过nuget软件包管理器=>软件包管理器控制台以及直接从解决方案中管理Nuget软件包来添加软件包.我正在尝试从像这样的Install-Package Newtonsoft.Json的软件包管理器安装Newtonsoft.Json，但是无法从源文件中找到

I was trying to add package through nuget package manager=> package manager console and from Manage Nuget packages from solution directly. I am trying to install Newtonsoft.Json from Package Manager Like this Install-Package Newtonsoft.Json but unable to find from the source i.e

 Name: nuget.org
 Source: https://api.nuget.org/v3/index.json

这给了我这样的结果:

PM> Install-Package Newtonsoft.Json
Install-Package : Unable to find package 'Newtonsoft.Json' at source ''.
At line:1 char:1
+ Install-Package Newtonsoft.Json
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : NotSpecified: (:) [Install-Package], Exception
+ FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PackageManagement.PowerShellCmdlets.InstallPackageCommand

Time Elapsed: 00:01:30.2571879

我认为这里的source是空白的.可能是因为它无法加载软件包.我试图管理程序包管理器设置，但无法连接.我的包管理器设置是这样的:

I think that the source here is blank. May be because of that it is unable to load packages. I have tried to manage the package manager setting but not been able to connect. My package manager setting is like this:

尽管互联网连接良好，但我无法安装软件包.我的问题是:

Despite of having good connection of internet I am not been able to install package. My questions are:

1. 我应该如何安装软件包?
2. 我在安装软件包时做错了什么?

推荐答案

假定您正在使用Windows操作系统 您在安装后是否初始化了vs 2017，或者是否更新了vs 2017?

Assuming you are using Windows OS Have you initialised vs 2017 after installation or Have you updated your vs 2017?

1. 如果没有，请初始化它.
2. 重新启动计算机.
3. 在vs 2017中打开您的项目

4. 检查您的nuget软件包管理器设置.

1. If not then please initialized it.
2. Restart your PC.
3. Open your project in vs 2017

4. Check your nuget package manager settings.

名称:nuget.org

Name:nuget.org

来源:api.nuget.org/v3/index.json

Source:api.nuget.org/v3/index.json

现在，从tools=>Nuget Package Manager=>Package Manager Console运行nuget软件包管理器并编写您的install-package命令，或者从tools=>Nuget Package Manager=>

Now, run nuget package manager from tools=>Nuget Package Manager=>Package Manager Console and write your install-package command or run Manage nuget package manager for solution from tools=>Nuget Package Manager=>
