java.io.IOException：无法打开“…”作为类路径，文件名或URL

Question

我得到了如下的Java IO异常：

Loading unnormalized dictionary from /Users/edamame/Documents/library/stanford/./data//dict/pku.non

似乎找不到"/Users/edamame/Documents/library/stanford/./data//dict/pku.non"

这是我的文件位置：

edamame$ pwd
/Users/edamame/Documents/library/stanford/data/dict
edamame$ ls
pku    pku.gz

我想知道Java到底期望我的文件在哪里？ 谢谢！ （PS。原始代码包装在python中，我在Mac上）

Answer 1

你有双斜线/前dict ：

 /Users/edamame/Documents/library/stanford/./data//dict/pku.non

更改为：

/Users/edamame/Documents/library/stanford/data/dict/pku.non

Answer 2

//路径中的///Users/edamame/Documents/library/stanford/./data//dict/pku.non

在语法上是错误的。 我不知道您如何组装此路径字符串，但必须解决此问题才能摆脱异常。
