-bash：类转储：找不到命令

Question

我已经从 http://www.codethecode.com/projects/class-dump/ 下载了类转储。 我用终端打开类转储，但结果如下：

  where options are:
        -a             show instance variable offsets

        -t             suppress header in output, for testing

我不明白如何运行类转储。请帮助我。

我在命令行上点击类转储，结果是：

yu-brooks-imac:桌面 yubrook$ 类转储
-bash：类转储：找不到命令

Answer 1

通过手动安装类转储并使用此Steve Nygard下载类转储。然后将类转储文件复制到以下位置“/usr/local/bin”。在此之后一切都会正常工作。

Answer 2

这是因为操作系统无法识别当前文件夹路径。 导航到您已下载代码的当前文件夹。运行如下：

./class-dump
