Why won't go language run on ubuntu 20.4?

Question

linux

I am an absolute beginner on this wonderful operating system. I installed the go language compiler from the official site, unpacked the archive and /usr/local/then added the following lines to the .bashrc file:

#User Settings
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

Now, even after restarting the computer, on command go versionit gives me my version of the compiler.
But the command go rungives an error go run: no go files listed

. I did not find information on this error. How can I solve the problem and run the compiler?

Answer 1

It's not a mistake. Open ANY tutorial on go, please

Answer 2

Go to the directory where the code is stored and run it there.

Answer 3

There are no *.go files in the folder, the compiler does not see them, there is nothing for it to compile

Answer 4

Hmm
Only installing another system will help
