eclipse - Erlang 没有用 spawn 返回任何东西

Question

我正在从youtube上的视频中学习 erlang 的基础知识。我被困在其中一个视频教程中。这是代码：

say_something(_,0) ->
    io:format("Done ~n");
say_something(Value, Times) ->
    io:format("~s ~n", [Value]),
    say_something(Value, Times-1).

start_concurrency(Value1, Value2) ->
    spawn(easy, say_something, [Value1, 3]),
    spawn(easy, say_something, [Value2, 3]).

say_something功能没问题：

(ErlangProject@Carl-PC)3> easy:say_something("Hello world", 3).
Hello world 
Hello world 
Hello world 
Done 
ok

但是，当我跑步时start_concurrency，我不知道会发生什么，但我没有得到我应该得到的东西，如下所示：

(ErlangProject@Carl-PC)4> easy:start_concurrency("Hello world", "Really Really").
easy:start_concurrency("Dynamically", "ee").
easy:start_concurrency("dfd", "dfd").

它不返回任何东西。我可以不停地打字。我究竟做错了什么？请帮我。

谢谢！

Ok, this solved the problem:

1. I had to change the Erlide plugin location on Eclipse with this plugin location.

This was the original post which helped me. Hope it will help others too!

• I tried this in 32 bit eclipse.
