Question

我正在尝试在Mountain Lion上安装GraphicsMagick并遇到问题。我尝试了所有可以在博客和其他stackoverflow问题中搜索的内容，但没有任何效果。所以我把每一个命令都带来了一大堆错误。请看看并帮助我。

当我跑步时

brew install graphicsmagick

我明白了

Warning: Could not link jpeg. Unlinking...
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using `brew link jpeg'

和

Warning: Could not link libpng. Unlinking...
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using `brew link libpng'

在最后我得到了

==> make install
Warning: Could not link graphicsmagick. Unlinking...
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using `brew link graphicsmagick'

Possible conflicting files are:
==> Summary
  /usr/local/Cellar/graphicsmagick/1.3.18: 283 files, 10M, built in 52 seconds

现在，如果我尝试brew link jpeg或brew link libpng，我会收到此错误

Linking /usr/local/Cellar/jpeg/8d... Warning: Could not link jpeg. Unlinking...

Error: Could not symlink file: /usr/local/Cellar/jpeg/8d/bin/wrjpgcom
Target /usr/local/bin/wrjpgcom already exists. You may need to delete it.
To force the link and overwrite all other conflicting files, do:
  brew link --overwrite formula_name

To list all files that would be deleted:
  brew link --overwrite --dry-run formula_name

如果我通过brew link --overwrite jpeg尝试覆盖方法，那就有效了。但是'brew link --overwrite libpng'我得到了这个

Linking /usr/local/Cellar/libpng/1.5.14... Warning: Could not link libpng. Unlinking...

Error: Permission denied - /usr/local/share/man/man5/png.5

之后，当我尝试brew link graphicsmagick时，我得到了：

Linking /usr/local/Cellar/graphicsmagick/1.3.18... Warning: Could not link graphicsmagick. Unlinking...

Error: Could not symlink file: /usr/local/Cellar/graphicsmagick/1.3.18/share/man/man5/quantize.5
/usr/local/share/man/man5 is not writable. You should change its permissions.

请帮帮我。提前谢谢。
