If everything you use Homebrew for is working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: "config" scripts exist outside your system or Homebrew directories. ./configure scripts often look for *-config scripts to determine if software packages are installed, and which additional flags to use when compiling and linking.

Having additional scripts in your path can confuse software installed via Homebrew if the config script overrides a system or Homebrew-provided script of the same name. We found the following "config" scripts: /Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7-config /Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7m-config /Library/Frameworks/Python.framework/Versions/3.7/bin/python3-config /Users/dongruixue/anaconda3/bin/icu-config /Users/dongruixue/anaconda3/bin/krb5-config /Users/dongruixue/anaconda3/bin/freetype-config /Users/dongruixue/anaconda3/bin/xslt-config /Users/dongruixue/anaconda3/bin/libpng16-config /Users/dongruixue/anaconda3/bin/python3.7-config /Users/dongruixue/anaconda3/bin/libpng-config /Users/dongruixue/anaconda3/bin/xml2-config /Users/dongruixue/anaconda3/bin/python3.7m-config /Users/dongruixue/anaconda3/bin/python3-config /Users/dongruixue/anaconda3/bin/curl-config /Users/dongruixue/anaconda3/bin/ncursesw6-config /Users/dongruixue/anaconda3/bin/pcre-config

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: python (base) dongruixuedeiMac:~ dongruixue$ brew link Usage: brew link, ln [options] formula

Symlink all of formula's installed files into Homebrew's prefix. This is done automatically when you install formulae but can be useful for DIY installations.

    --overwrite                  Delete files that already exist in the
                                 prefix while linking.
-n, --dry-run                    List files which would be linked or deleted
                                 by brew link --overwrite without actually
                                 linking or deleting any files.
-f, --force                      Allow keg-only formulae to be linked.
-v, --verbose                    Make some output more verbose.
-d, --debug                      Display any debugging information.
-h, --help                       Show this message.
