我正在尝试在Mountain Lion上安装GraphicsMagick并遇到问题。我尝试了所有我可以在博客中搜索的内容以及其他stackoverflow问题，但没有任何效果。因此，我将在每个命令中遇到的所有错误归纳为一堆。请看看并帮助我。
当我运行时
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'
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，则会收到此错误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
如果我通过执行
brew link --overwrite jpeg尝试覆盖方法，则它可以工作。但是'brew link --overwrite libpng'我明白了Linking /usr/local/Cellar/libpng/1.5.14... Warning: Could not link libpng. Unlinking...
Error: Permission denied - /usr/local/share/man/man5/png.5
然后，当我尝试
brew link graphicsmagick时，我得到: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.
请帮我。提前致谢。
最佳答案
尝试删除所有内容，然后重新开始:
brew uninstall imagemagick graphicsmagick libpng jpeg
brew cleanup -s
brew install graphicsmagick
