JS配置内容

{
    "localPath" : "../source/self/fonts/",
    "onlinePath" : "../self/fonts/",
    "url" :  [
        "http://localhost:4000/"
    ]
}

注：服务器在本地上，用hexo s生成的，所以用的本地链接

又测试了一下，服务端测试也会报这个错误

检查下本地的localpath路径是不是可以找的到

检查下本地的localpath路径是不是可以找的到

本地测试的话会有相对路径的问题，我在另一个issuse中写了。
我不知道本地测试会不会有这个问题，因为我不清楚这两个错误如果都有的话应该哪一个先发生。
