在尝试连接到Nuget时,我得到了下面的错误,然后我无法连接:

无法加载源的服务索引 https://api.nuget.org/v3/index.json。 发送请求时发生错误。 无法连接到远程服务器 连接尝试失败,原因是被连接方在一段时间后没有正确响应,或已建立连接 由于连接的主机未能响应68.232.34.200:443而失败

我可以在浏览器上访问https://api.nuget.org/v3/index.json。

在我的情况下,发生这种情况是因为我没有互联网连接,它正在试图搭建

其他回答

好吧,我尝试了上面所有的答案,希望我的注册表现在不是软管。但这似乎解决了我的问题:

添加这个:TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384

到this中逗号分隔的字符串:

微软HKLM \ SOFTWARE \政策\ \ SSL加密\ Configuration \ \ 00010002

我希望这能帮助下一个希望在周六早上快速进行有趣的概念验证,然后花3个小时寻找解决方案的人!!

我在Windows 10中使用docker-compose up命令在Dockerfile中运行RUN dotnet restore时遇到了同样的错误。

我已经尝试了互联网上提供的所有可能的解决方案,也一直在关注这个公开的问题。最后,在花了8个多小时后,通过遵循前面的步骤,我能够解决我的问题。

Uninstall Docker from your system Restart your system Install Docker from this link. Below is the version of my Docker Restart your system Start Docker for Windows, search Docker in the search bar in Windows. Make sure it is running. You should also go to Services.msc and make sure the services Docker Engine and Docker for Windows Service are running. At last, you must check your Nuget.config file from C:\Users\{Username}\AppData\Roaming\NuGet. For me, the content of that file was as below. <?xml version="1.0" encoding="utf-8"?> <configuration> <packageSources> <add key="nuget.org" value="https://api.nuget.org/v3/index.json" /> </packageSources> <packageRestore> <add key="enabled" value="True" /> <add key="automatic" value="True" /> </packageRestore> <bindingRedirects> <add key="skip" value="False" /> </bindingRedirects> <packageManagement> <add key="format" value="0" /> <add key="disabled" value="False" /> </packageManagement> </configuration> Hope this helps.

禁用防病毒应用程序。 以我为例,AVG阻止我访问nuget.org

有些东西可能改变了你的代理设置,比如Fiddler。关闭Fiddler,然后关闭Visual Studio并再次打开它。

我在Visual Studio 2015上执行Install-Package Modernizr时遇到了类似的问题。我通过以下步骤解决了这个问题:

Download the package from its online source. Go to Tools/NuGet Package Manager/Package Manager Settings. Select Package Sources from the window. Add a new package source by clicking on the + sign. Enter a name and source location by clicking on ... (triple dot) sign. Make sure that only the package source that you've just added is checked. Uncheck all the other package sources. Go to Package Manager Console and type Install-Package Modernizr. Visual Studio 2015 installs the package automatically and creates Scripts and packages folders in your root folder.

我希望同样的解决方案在安装其他包时也能起作用。
