NuGet中的输入字符串格式不正确

Question

我正在尝试在我的一个项目中安装Ninject,并给出确切的版本和项目名称.我正在使用本地托管的包存储库.我在包安装过程中面临以下问题:

PM> Install-Package Ninject -version 3.2.2.0 -project My.Project.Name
Installing 'Ninject 3.2.2.0'.
You are downloading Ninject from Ninject Project Contributors, the license agreement to which is available at https://github.com/ninject/ninject/raw/master/LICENSE.txt.

之后:

• 该记录将添加到项目目录中的packages.config中
• 打包将添加到解决方案目录中的packages目录中
• 库未被引用
• 依赖库未处理.

我怎样才能修补它？什么可能导致这个问题？

Answer 1

我不知道究竟是什么导致了这个问题,但我们能够通过使用管理员凭据运行以下命令来解决它:

regsvr32 "C:\Program Files (x86)\Common Files\microsoft shared\MSEnv\VsLangproj.olb"

但是,请务必以管理员身份启动命令行(不仅仅是runas),否则您将看到成功消息,尽管注册实际上已失败.

之后重新启动Visual Studio并且它应该可以工作(至少它对我有用,在VS 2010/2013/2013的几台机器上进行了测试).
