如何解決我的brew醫生錯誤？

Question

我的山獅終端上運行的BREW醫生，我得到以下錯誤：

 

Warning: /usr/local/etc isn't writable. 
This can happen if you "sudo make install" software that isn't managed 
by Homebrew. 

If a brew tries to write a file to this directory, the install will 
fail during the link step. 

You should probably `chown` /usr/local/etc 
Warning: Some directories in /usr/local/share/man aren't writable. 
This can happen if you "sudo make install" software that isn't managed 
by Homebrew. If a brew tries to add locale information to one of these 
directories, then the install will fail during the link step. 
You should probably `chown` them: 

    /usr/local/share/man/man8 

          
   
   Warning: Your XQuartz (2.7.2) is outdated Please install XQuartz 2.7.4. 
   
Warning: Unbrewed dylibs were found in /usr/local/lib. 
If you didn't put them there on purpose they could cause problems when 
building Homebrew formulae, and may need to be deleted. 

Unexpected dylibs: 
    /usr/local/lib/libicudata.49.1.2.dylib /usr/local/lib/libicui18n.49.1.2.dylib /usr/local/lib/libicuio.49.1.2.dylib /usr/local/lib/libicule.49.1.2.dylib /usr/local/lib/libiculx.49.1.2.dylib /usr/local/lib/libicutest.49.1.2.dylib /usr/local/lib/libicutu.49.1.2.dylib /usr/local/lib/libicuuc.49.1.2.dylib 
Warning: Unbrewed .pc files were found in /usr/local/lib/pkgconfig.

Warning: Unbrewed static libraries were found in /usr/local/lib. 
If you didn't put them there on purpose they could cause problems when 
building Homebrew formulae, and may need to be deleted. 

Unexpected static libraries: 
    /usr/local/lib/libc-client.a 
Warning: Homebrew's sbin was not found in your path. 
Consider amending your PATH variable so it contains: 
    /usr/local/sbin 
 

我怎樣才能解決這些錯誤？ 解決它們至關重要，否則我可能會忽略它們？ 謝謝。

如果你仔細閱讀的文字，你會發現，它實際上告訴您如何修正錯誤：

You should probably `chown` /usr/local/etc 

You should probably `chown` them: 

    /usr/local/share/man/man8 

dylibs，.PC文件..

may need to be deleted 

所以，改變將提及的目錄的所有者提供給用戶，並刪除不需要的文件（如果您沒有故意將它們放在那裏）。
