Golang错误“找不到命令”

Question

I'm trying to run golang in an interactive mode.

I want to use go-eval for that, I followed the README instructions:

• I ran go get github.com/sbinet/go-eval/ successfully
• I ran go-eval which resulted in -bash: go-eval: command not found

Some more information:

• echo $PATH returns: /usr/local/go/bin:...

• echo $GOPATH returns: $HOME/golang

• running whereis go-eval returns no output

• running go install go-eval returns:

  can't load package: package go-eval: cannot find package "go-eval" in any of: /usr/local/go/src/go-eval (from $GOROOT) $HOME/golang/src/go-eval (from $GOPATH)

Answer 1

You need to add GOPATH/bin to PATH.

PATH="$GOPATH/bin:$PATH"

Update: Starting with Go 1.8, GOPATH defaults to $HOME/go if not set. The above will not work if GOPATH is not explicitly set.

To set both, add this to your .profile:

export GOPATH="$HOME/go"
PATH="$GOPATH/bin:$PATH"
