Why Can't Go Find My Package During `go build`?

Troubleshooting "Cannot find package" Error in Go "go build"

If you encounter the "cannot find package" error while using "go build" or "go run," despite a properly set GOPATH, here are the potential causes and solutions:

Incorrect Directory Structure

The error can occur if the source file is not located in a directory with the same name as the imported package. In your example, the source file foobar.go should be placed in /home/mitchell/go/src/foobar, not in the root directory of the GOPATH.

Solution:

Move foobar.go to the correct directory:

mv ~/foobar.go /home/mitchell/go/src/foobar/foobar.go

Recommended Additional Steps:

• Add $GOPATH/bin to your $PATH for easy access to Go executables.
• Move main.go to a subfolder of $GOPATH/src, such as $GOPATH/src/test/.
• Run "go install test" to create an executable in $GOPATH/bin that you can run directly.

Incorrect GOPATH Setting

Verify that the GOPATH environment variable is set to a valid directory where you want to store your Go code.

Example:

export GOPATH="$HOME/go"

Additional Troubleshooting Tips:

• Check for any typos or errors in the import statement.
• Ensure that the imported package is built and installed properly.
• Restart your IDE or terminal to refresh the environment variables.
• Refer to the Go documentation on package structure and import paths for further guidance.
