Lein REPL始终显示连接被拒绝 [英] Lein REPL always shows Connection Refused

问题描述

我一直在试图让Leiningen在我的Mac上工作。但是每当我运行lein repl我得到以下响应：

I've been trying to get Leiningen to work on my Mac. However whenever I run "lein repl" I get the following response:

localhost:~ KJ$ lein repl

现在我使用Java 1.8运行Leiningen 2.3.4。我也试过Leiningen 2.4.3，得到了相同的结果。我在这里找到了这个问题，这似乎是问题，但它说它解决了2.3.4。我从leiningen网站安装了2.4.3，使用homebrew安装了2.3.4。在问题线程中的一个建议是尝试它与WiFi关闭。当我这样做，repl连接成功，但这显然是不理想的。

Right now I'm running Leiningen 2.3.4 with Java 1.8. I have also tried with Leiningen 2.4.3 and gotten the same result. I found this issue here and that seems to be the issue, but it says it's solved in 2.3.4. I installed 2.4.3 from the leiningen site and 2.3.4 using homebrew. One suggestion in the issue thread is to try it with wifi turned off. When I do this, the repl connects successfully but this is obviously not ideal.

有没有任何解决方法？

Are there any workarounds for this?

编辑：我已经查看了我的hosts文件，但我不知道什么更改。这是它现在是：

I've looked around my hosts file but I'm not exactly sure what to change. Here's what it is right now:

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1       localhost
255.255.255.255 broadcasthost
::1             localhost
fe80::1%lo0     localhost

推荐答案

Java 1.8中仍然存在上面链接的问题。我能够通过降级到Java 1.7来解决这个问题。

The issue I linked to above still exists for Java 1.8. I was able to solve the problem by downgrading to Java 1.7 instead.
