Setting GOPATH to Fix "$GOPATH not set" Error
When attempting to install packages using "go get," you may encounter the error "cannot download, $GOPATH not set." This error indicates that the GOPATH environment variable, which specifies the directory used for Go packages, has not been set.
Setting GOPATH on macOS
To set GOPATH on macOS, do the following:
- Open your terminal.
- Execute the following command:
export GOPATH="$HOME/your-workspace-dir/"
- Add the following line to your ~/.bashrc or equivalent shell configuration file:
export GOPATH="$HOME/your-workspace-dir/"
This will set GOPATH permanently for future use.
GOPATH Layout
Go installs packages under the following subdirectories within the GOPATH directory:
- src/: Source code for Go packages
- bin/: Compiled binaries
- pkg/: Compiled package objects
You should place your own packages under the $GOPATH/src** directory, organized according to their import paths (e.g., **$GOPATH/src/github.com/myusername/).
Additional Tips
- For faster navigation to package directories in bash, set CDPATH.
- Set GOPATH=$HOME to place Go's directories directly under your home directory.

Effective Go application error logging requires balancing details and performance. 1) Using standard log packages is simple but lacks context. 2) logrus provides structured logs and custom fields. 3) Zap combines performance and structured logs, but requires more settings. A complete error logging system should include error enrichment, log level, centralized logging, performance considerations, and error handling modes.

Interface combinations build complex abstractions in Go programming by breaking down functions into small, focused interfaces. 1) Define Reader, Writer and Closer interfaces. 2) Create complex types such as File and NetworkStream by combining these interfaces. 3) Use ProcessData function to show how to handle these combined interfaces. This approach enhances code flexibility, testability, and reusability, but care should be taken to avoid excessive fragmentation and combinatorial complexity.
