【问题描述】：

我关注https://dotnet.microsoft.com/learn/dotnet/hello-world-tutorial/create

当我尝试创建一个项目时，我得到以下信息：

oskar@oskarslaptop:~/Programming/Resorvoir-CLI$ dotnet new console -o MyApp
Segmentation fault (core dumped)

我已经通过 snap 安装了 dotnet 5.0：

sudo snap install dotnet-sdk --classic --channel=5.0
sudo snap alias dotnet-sdk.dotnet dotnet

快照信息：

oskar@oskarslaptop:~/Programming/Resorvoir-CLI$ sudo snap info dotnet-sdk

【解决方案1】：

我认为这是 snap 本身的问题。用 pacman 代替 snap

sudo snap remove dotnet-sdk
sudo pacman -S dotnet-sdk

这里有更多关于这个问题的信息 https://github.com/dotnet/sdk/issues/11639

【讨论】：

Pop OS 不是基于 Arch 的发行版，它位于 debain-ubuntu 区域。我认为我不应该在这里使用 pacman？

【解决方案2】：

POP 操作系统基于 Ubuntu。如果您通过 snap install 安装了 dotnet 运行时，则只能通过“sudo dotnet ...”访问它。我在 VS Code 中遇到了同样的问题，它在没有 sudo 的情况下运行 dotnet 命令，并且我收到了“分段错误（核心转储）”错误。我通过 apt-get 安装 dotnet 运行时解决了（现在安装在“/usr/bin ...”中并且无需 sudo 即可工作（参见：https://docs.microsoft.com/en-us/dotnet/core/install/linux-ubuntu#2004-））
