如何修复新建dotnet项目时的“分割错误(核心转储)”？

Question

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

当我尝试创建一个项目时，我得到了以下信息：

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

我使用以下命令通过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

Answer 1

POP操作系统是基于Ubuntu的。如果您通过snap install安装了dotnet运行时，则可以通过"sudo dotnet ...“访问它。只有这样。我在VS代码中也遇到了同样的问题，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运行时解决了这个问题(现在安装在"/usr/bin ...“在没有sudo的情况下工作(参见：https://docs.microsoft.com/en-us/dotnet/core/install/linux-ubuntu#2004-)

Answer 2

我认为这就是snap本身的问题所在。使用pacman代替snap

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