我在 ubuntu 22.04 版本中使用 dotnet6。现在，当我运行 dotnet --version 时，出现以下错误。
jyothish@jyothish-Lenovo-G570:~$ dotnet --version
The command could not be loaded, possibly because:
* You intended to execute a .NET application:
The application '--version' does not exist.
* You intended to execute a .NET SDK command:
No .NET SDKs were found.

jyothish@jyothish-Lenovo-G570:~$
当我同时运行 dotnet --help 和 dotnet --list-runtimes 时，我得到了输出。
jyothish@jyothish-Lenovo-G570:~$ dotnet --list-runtimes

我该如何纠正这个问题并在 ubuntu 中恢复使用 dotnet6？
答案1
正如消息所示，您没有安装 SDK。我猜您只有运行时。请执行以下操作：
sudo apt install dotnet6
如果它告诉你有错误，请这样做
sudo apt -f install
如果这不起作用，请卸载所有 dotnet 软件包并重新安装 dotnet6
