Nuget添加新項目的問題

為已有的幾個項目添加了一個nuget package 后，在解決方法中添加了一個新項目，然后想把這個nuget package添加到這個新建的項目中去，可以此時無法添加。

 

 

怎么辦那？

【解決方法】

There's 3 approaches :).
In NuGet 1.1 (The latest release) we've improved powershell pipelining so you can do this:

Get-Project -All | Install-Package SomePackage

That will install "SomePackage" into all of your projects. You can use wildcards to narrow down which projects:

Get-Project Mvc* | Install-Package SomePackage

That will use wildcard semantics (in this case, find all projects that start with mvc).

Get-Project SomeProject | Install-Package SomePackage

That will install SomePackage into SomeProject and nothing else.

 

 

如果在運行的時候出現如下的提示：

<Project name> already has a reference to <Package>.

那就檢查一下項目的package.config文件，如果已經有了引用，就刪掉。另外也看一下項目的references，如果有了，也刪掉。

 

如果在運行命令的時候，出現了如下的錯誤信息。

Install-Package : An error occurred while loading packages

from'https://www.nuget.org/api/v2/curated-feeds/microsoftdotnet/': The underlying connection was closed: Could not

establish trust relationship for the SSL/TLS secure channel.

At line:1 char:45

+ Get-Project NotesDataExporterCloud.Common | Install-Package Newtonsoft.Json

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+ CategoryInfo : NotSpecified: (:) [Install-Package], InvalidOperationException

+ FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PowerShell.Commands.InstallPackageCommand

 

原因是www.nuget.org的證書過期了，解決方法是添加自己的Package Source.

 

注意machine-wide package sources 下面的checkbox一定要勾掉，不然的話運行命令的時候會用這個來鏈接Nuget,還是會報證書的錯誤。
