无法运行BREW的医生，它给了警告

Question

我试图运行在终端上酿造的医生，但是当我这样做，它告诉我一些警告...我贴吧：

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/libjansson.4.dylib 
    /usr/local/lib/libusb-1.0.0.dylib 

Warning: Unbrewed .la files were found in /usr/local/lib.

Warning: Unbrewed static libraries were found in /usr/local/lib.

Warning: You have unlinked kegs in your Cellar 
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on 
those kegs to fail to run properly once built. Run `brew link` on these: 

    jansson 
    libidn 
    libtool 
    libusb
