Question

我已经搜索了一段时间，但是在2019年我没有发现关于如何从Mac上的.Net Core获得多个版本的任何准确信息。我的用例是，我使用.Net Core 2.2进行主动开发，并且我想使用.Net Core 3及其现在的优点，如Razor Components和Blazor之类。

我找到了有关.Net Core多个版本如何在Windows上的同一系统上运行的文章。但是，Mac不是Windows（幸运的是，不幸的是，不是Windows），我想用brew作为软件包管理器，而不是我来管理版本。如果可能的话，我不想离开酿造区。

我尚未找到有关brew如何帮助我的信息，而是抛出一条错误消息，提示它将覆盖dotnet命令。

我找到了有关DNVM的文章，但事实证明它与.Net Core 1.x有关，从那时起似乎不可用。

例如使用brew，如何从.Net Core获得多个版本？如果brew无法做到这一点，那么建议的方法是什么？

Answer 1

聚会晚了一点，但是您现在可以用dotnet-sdk-versions水龙头来完成此操作。

您可以在这里找到它：https://github.com/isen-ng/homebrew-dotnet-sdk-versions

brew tap isen-ng/dotnet-sdk-versions
brew cask install dotnet-sdk-2.2.100

dotnet --list-sdks

免责声明：我两天前写了水龙头

Answer 2

dotnet core 3预览有一个容器，您可以使用以下命令安装最新的预览

$ brew cask install dotnet-sdk-preview

安装后，您可以看到

$ dotnet --info

看来Brew无法帮助您，或者至少我没有找到解决方案。但是，仅从.Net Core网站下载和安装程序包即可解决此问题。安装两个版本的SDKS，您将同时拥有。

这对我有用：

brew cask install \
  https://raw.githubusercontent.com/Homebrew/homebrew-cask/master/Casks/dotnet-sdk.rb

带有brew的Macos上的.Net Core的多个版本
