Error: The `brew link` step did not complete successfully

The formula built, but is not symlinked into /usr/local

Could not symlink share/aclocal/cmake.m4

/usr/local/share/aclocal is not writable.

 

You can try again using:

  brew link cmake

==> Caveats

Emacs Lisp files have been installed to:

  /usr/local/share/emacs/site-lisp/cmake

==> Summary

🍺  /usr/local/Cellar/cmake/3.9.6: 2,267 files, 31.7MB

 

brew install cmake

Warning: cmake 3.9.6 is already installed, it's just not linked.

You can use `brew link cmake` to link this version.

 

x-MacBook-Pro:primecount-master zilong$ brew link cmake

哦，原来是权限问题，那么通过赋权即可

 

sudo chown -R `whoami`:admin /usr/local/share/aclocal

再敲一遍即可

brew link cmake
