I figured out a solution: Because the error says PKG_CONFIG_PATH could not find 'sqlite3. pc, So I first find 'sqlite3 under/usr/local. pc: Where can I add this path to the Environment Variable? find/usr/local/-name "sqlite3.pc"/usr/local/Cellar/sqlite/3.7.15.1/lib/pkgconfig /sqlite3.pcajian @ Ajians-MacBook-Pro: /usr $ export PKG_CONFIG_PATH =/usr/lib/pkgconfig:/usr/lib:/usr/local/Cellar/sqlite/3.7.15.1/lib/pkgconfigajian @ Ajians-MacBook-Pro: /usr $ go get github.com/mattn/go-sqlite3..
