尝试使用Visual Studio 2015从命令行构建旧项目(VS2010).但是,我得到了这个:

C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.Cpp.Platform.targets(55,5): error MSB8020: The build tools for Visual Studio 2010 (Platform Toolset = 'v100') cannot be found. To build using the v100 build tools, please install Visual Studio 2010 build tools.  Alternatively, you may upgrade to the current Visual Studio tools by selecting the Project menu or right-click the solution, and then selecting "Retarget solution".

任何人都知道如何从命令行"重新定位解决方案"？

只是试图删除一个目录。不能，因为not owner错误。

iex(1)> File.mkdir "testing"
:ok
iex(2)> File.rm! "testing"
** (File.Error) could not remove file "testing": not owner
    (elixir) lib/file.ex:1128: File.rm!/1
iex(2)> File.rm! "testing/"
** (File.Error) could not remove file "testing/": not owner
    (elixir) lib/file.ex:1128: File.rm!/1
iex(2)> File.rm! "./testing/"
** (File.Error) could not remove file "./testing/": not owner
    (elixir) lib/file.ex:1128: File.rm!/1

一定是一些简单的事情，我只是没有从文档中正确阅读，对吧？
