failed to install

Hello! I tried to install the 'RccpMeCab' package, but failed. I have installed the 'RMeCab' package, and when I ran install.packages("RccpMeCab"), the information returned is as following:

Can you help me to fix the problem?

Hi @SyuuGenn ,

/bin/sh: mecab-config: command not found

means that you didn't install MeCab libraries before installing the package, or R shell couldn't find the libraries.

Your system is MacOS X, therefore downloading MeCab source and IPA dictionary.

In the Terminal, go to the directory you downloaded two files and run following commands:

 $ tar zxfv mecab-0.996.tar.gz
 $ cd mecab-0.996
 $ ./configure 
 $ make
 $ make check
 $ sudo
 $ make install

and

$ tar zxfv mecab-ipadic-2.7.0-200720801.tar.gz
$ cd mecab-ipadic-2.7.0-20070801
$ ./configure
$ make
$ su
$ make install

It is little bit weird for me, since you installed RMeCab and it needs MeCab library too. Maybe you should check your PATH variable. Is which mecab-config (in the Terminal) returns the directory?

Thank you, @junhewk ! I ran your code, and then installed "RccpMeCab" successfully.
