Question

我是clojure的新手，在我完成第一个clojure Hello World项目之后，我尝试启动repl但是我遇到了Connection denied错误。请帮忙！

我输入的命令是lein repl

Exception in thread "main" java.net.ConnectException: Connection refused, compiling:(/private/var/folders/wz/jk4mqxs57fb4m27sly8fyqkh0000gn/T/form-init1330852264199133435.clj:1:124)

遇到同样的问题，可以通过运行无头repl，然后在另一个shell中连接到它来解决这个问题

> lein repl :headless
nREPL server started on port 9991 on host 127.0.0.1 - nrepl://127.0.0.1:9991

然后在另一个shell

> lein repl :connect nrepl://127.0.0.1:9991

Clojure repl连接已关闭
