[英]Run dotnet application on Ubuntu 20.04
I am newbie in net core on Linux and i have a question.我是 Linux 上 net core 的新手,我有一个问题。 I installed .net core 5 and wrote hello world app with name "hello".我安装了 .net core 5 并编写了名为“hello”的 hello world 应用程序。 After, I go to the project bin directory and run my app like:之后,我转到项目 bin 目录并运行我的应用程序,如下所示:
dotnet hello.dll
All fine.一切都很好。 But i see "hello" (shared library) file in the bin directory too.但是我在 bin 目录中也看到了“hello”(共享库)文件。 I can run it in terminal like:我可以在终端中运行它,如:
./hello
All works... But when i copy files in another location (away from project directory), i can't run my app like: ./hello I get message "Segmentation fault (core dumped)" in terminal.一切正常...但是当我将文件复制到另一个位置(远离项目目录)时,我无法运行我的应用程序,例如:./hello 我在终端中收到消息“Segmentation fault (core dumped)”。
Someone, please, tell me, why after copy files, command "./hello" doesn't work (but dotnet hello.dll works).请有人告诉我,为什么复制文件后,命令“./hello”不起作用(但 dotnet hello.dll 起作用)。
Ubuntu 20.04 Ubuntu 20.04
.NET SDK installed: 5.0.301 .NET SDK 安装:5.0.301
.NET runtimes installed: 5.0.7安装的 .NET 运行时:5.0.7
UPDATE project location:更新项目位置:
/RiderProjects/RabbitMq-example/RabbitMq-example/bin/Debug/net5.0
i copy only net5.0 folder to:我只将 net5.0 文件夹复制到:
/RiderProjects/RMQ/net5.0
And I get Segmentation fault.我得到了分割错误。
If i copy full bin folder (like:如果我复制完整的 bin 文件夹(例如:
/RiderProjects/RMQ/bin/Debug/net5.0
All fine.一切都很好。
Steps:脚步:
If you installed the dotnet runtime via snap install you can access it via "sudo dotnet ..." only.如果您通过 snap install 安装了 dotnet 运行时,则只能通过“sudo dotnet ...”访问它。 I had the same problem in VS Code, it runs the dotnet commands without sudo and I recived the "Segmentation fault (core dumped)" error.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,我收到了“分段错误(核心转储)”错误。 I solved by installing the dotnet runtime via apt-get (now is installed in "/usr/bin ..." and works without sudo (see: https://docs.microsoft.com/en-us/dotnet/core/install/linux-ubuntu#2004- ))我通过 apt-get 安装 dotnet 运行时解决了(现在安装在“/usr/bin ...”中,无需 sudo 即可工作(请参阅: https : //docs.microsoft.com/en-us/dotnet/core/安装/linux-ubuntu#2004- ))
