我正在尝试安装名为MFOC的工具。我按照其网站上提到的说明进行了操作：

ebrahim@ubuntu:~$ cd Desktop/mfoc-master/

ebrahim@ubuntu:~/Desktop/mfoc-master$ mfoc -h
No command 'mfoc' found, did you mean:
 Command 'moc' from package 'qtchooser' (main)
 Command 'mdoc' from package 'monodoc-base' (main)
mfoc: command not found
ebrahim@ubuntu:~/Desktop/mfoc-master$

如上所述，似乎make命令存在问题，之后我无法使用该工具。我该如何处理这个问题？

Answer 1

简单明了mfoc查看PATH中的目录，这些目录中没有（也不应该）包含当前目录。

如果当前目录中有要运行的工具，请指定路径。当前目录的相对路径只是./。

./mfoc

更一般地说，要在不在PATH中的目录中运行工具，请指定该目录的（相对或绝对）路径;

../mfoc-master/mfoc   # look in "mfoc-master" within the parent dir (..)
~/Desktop/mfoc-master/mfoc   # relative to home dir (~)
/home/ebrahim/Desktop/mfoc-master/mfoc   # absolute path

如果您希望在PATH中安装该工具，则命令make install通常会这样做。

“executable：command not found”虽然“make executable”成功了
