Cmd优先级：在2个位置安装时如何使用正确的dotnet.exe？ [英] Cmd precedence: How to use correct dotnet.exe when installed in 2 locations?
问题描述
前一段时间，我手动安装了dotnet core 2.1.2 SDK，方法是将其解压缩到我的％AppData％文件夹中，并将其位置添加到PATH环境变量中。
这很好，我可以通过cmd调用dotnet命令，而VS Code选择了正确的位置。
a while ago I installed the dotnet core 2.1.2 SDK manually, by unzipping it into my %AppData% folder, and adding its location to the PATH environment variable. This worked well, I could invoke the dotnet commands via cmd, and VS Code picked up the correct location.
最近，我安装了Visual Studio 2017。将Net Core 1.1 SDK安装到％ProgramFiles％\dotnet。
即使未在PATH变量中注册该特定路径，也似乎默认使用了该文件夹中的dotnet.exe。
Recently, I installed Visual Studio 2017, which installed the net core 1.1 SDK to %ProgramFiles%\dotnet. Even though this particular path isn't registered in the PATH variable, it seems the dotnet.exe from this folder is now used by default.
或者在换句话说，当我打开cmd.exe并键入 where dotnet时，我看到两个位置：
Or in other words, when I open cmd.exe and type "where dotnet", I see two locations:
- ％ProgramFiles％\dotnet＼ ＼dotnet.exe（由Vs2017安装的1.1 SDK）
- ％AppData％.... \dotnet\dotnet.exe-即2.1.2我手动解压缩的SDK
当我运行 dotnet --version时，我看到的是1.1.0-所以默认dotnet命令似乎与％ProgramFiles％文件夹中的旧1.1版本相关。
When i run "dotnet --version", I see 1.1.0 - so the default dotnet command seems to be associated with the old 1.1 version from the %ProgramFiles% folder.
如何在此处更改优先级-例如我该如何将dotnet命令与我的自定义文件夹关联？
How can I change the precedence there - e.g. how can I have the dotnet command be associated with my custom folder instead?
我应该注意我在非管理员Windows帐户上运行。我自己无法更改％ProgramFiles％文件夹中的任何内容（因此无法将较新的SDK复制到该文件夹，也无法删除/更改旧的SDK）。
I should note I am running on a non-admin windows account. I cannot change anything in the %ProgramFiles% folder myself (so cannot copy over the newer SDK to that folder, or delete/change the old one).
谢谢
推荐答案
尝试更改％PATH％环境变量，使其仅包含一个.NET文件夹。
Try to change the %PATH% environment variable so it includes only one of the .NET folders.
