That is a very odd error. 这是一个非常奇怪的错误。 Have you by accident deleted the compile.beam file from your OTP installation? 您是否偶然从OTP安装中删除了compile.beam文件？ A re-installation of R13B02 might solve it, if you don't want to change the OTP version. 如果您不想更改OTP版本，重新安装R13B02可能会解决此问题。

But if you don't need to use R13B02 for any particular reason, I recommend taking the opportunity to uninstall it and install the latest version (R14B03) instead ( http://www.erlang.org/download.html ). 但如果您因任何特殊原因不需要使用R13B02，我建议您借此机会将其卸载并安装最新版本（R14B03）（ http://www.erlang.org/download.html ）。 There have been many improvements, in particular regarding type specifications. 已经有许多改进，特别是关于类型规格。

What does io:format("~p~n", [code:get_path()]). 什么是io:format("~p~n", [code:get_path()]). print? 打印？ It should contain a directory like somepath/lib/compiler-4.7.2/ebin . 它应该包含一个像somepath/lib/compiler-4.7.2/ebin这样的目录。 Check that that directory actually exists, and that it contains the file compile.beam . 检查该目录是否确实存在，并且它包含文件compile.beam 。
