無法運行BREW的醫生，它給了警告

Question

我試圖運行在終端上釀造的醫生，但是當我這樣做，它告訴我一些警告...我貼吧：

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. 
If you didn't put them there on purpose they could cause problems when 
building Homebrew formulae, and may need to be deleted. 

Unexpected .la files: 
    /usr/local/lib/libjansson.la 

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/libjansson.a 
    /usr/local/lib/libusb-1.0.a 

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 

Answer 1

好，聽起來好像你可能已經自己安裝了libjansson和libusb工具，而不使用brew。

從

除此之外，按照它的指示，並運行下面的命令......

brew link jansson 
brew link libidn 
brew link libtool 
brew link libusb 

它可能會要求你添加的--overwrite標誌，你可以先檢查什麼動作是將採取通過增加--dry-run旗也是。
