带有 brew 的 Mac 上的多个版本的 .Net Core

Question

我已经搜索了一段时间，但我在 2019 年没有找到任何关于我如何在 Mac 上拥有 .Net Core 的多个版本的准确信息。我的用例是，我使用 .Net Core 2.2 进行主动开发，我想玩 .Net Core 3 以及它现在拥有的优点，例如 Razor Components 和 Blazor 东西。

我在 Windows 上找到了关于 .Net Core 多版本如何在同一系统上运行的文章，这太棒了。但是，Mac 不是 Windows（幸运的是，不幸的是），我想使用 brew 作为包管理器来处理管理版本而不是我。如果可以，我不想搬出酿造区。

我还没有找到关于 brew 如何帮助我的信息，而是它抛出一条错误消息，指出它将覆盖 dotnet 命令。

我找到了关于 DNVM 的文章，但结果发现它是关于 .Net Core 的东西1.x，从那时起似乎无法使用。

如何使用 brew 从 .Net Core 获得多个版本？如果 brew 不能这样做，那么建议的方法是什么？

Answer 1

看来brew帮不上忙了，至少我还没找到解决办法。但是，只需从 .Net Core 网站下载并安装软件包即可解决问题。安装这两个版本的 SDKS，您将同时拥有这两个版本。

有 dotnet core 3 预览版可用的 cask，您可以使用以下命令安装最新的预览版

$ brew cask install dotnet-sdk-preview

安装后可以看到

$ dotnet --info

晚会有点晚了，但您现在可以使用 dotnet-sdk-versions 点按来完成此操作。

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 install --cask dotnet-sdk2-2-100

dotnet --list-sdks

免责声明：我在 2 天前写了 tap

Answer 4

这对我有用：

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