Why Doesn't `go-eval` Work After Installation?

Resolving "command not found" for go-eval After Installation

Attempting to execute go-eval after installation results in a "command not found" error. Despite following the installation instructions for go-eval by successfully running 'go get', the command remains inaccessible.

This issue arises because the go-eval executable is located in '$GOPATH/bin', which is not part of the $PATH environmental variable. To resolve this, you need to add '$GOPATH/bin' to your PATH.

In older versions of Go (below 1.8):

PATH="$GOPATH/bin:$PATH"

In Go 1.8 and above, GOPATH defaults to $HOME/go. Therefore, the following commands are recommended in the .profile file:

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

After making these changes, you should be able to run go-eval by typing its command in the terminal without encountering the "command not found" error.
