Błędy Homebrew w Mac OS Mavericks podczas próby zainstalowania scala

Question

Właśnie zainstalowałem Mavericks i spróbowałem zainstalować język programowania w wersji brew install scala, ale nie udało się. Następnie wpisałem brew update, ale nadal nie można zainstalować scala. Dlatego wysyłam komendę brew doctor, aby pomóc czytelnikom stackoverflow pomagającym mi w rozwiązaniu tego problemu. Oto wynik:

$ brew doctor

Warning: /usr/local/etc isn't writable. This can happen if you "sudo make install" software that isn't managed by 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: "config" scripts exist outside your system or Homebrew directories. ./configure scripts often look for *-config scripts to determine if software packages are installed, and what 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:

/opt/local/bin/libpng-config 
/opt/local/bin/libpng15-config 
/opt/local/bin/ncurses5-config 
/opt/local/bin/ncursesw5-config 
/opt/local/bin/pkg-config 
/opt/local/bin/xml2-config 

Warning: You have MacPorts or Fink installed: /opt/local/bin/port

This can cause trouble. You don't have to uninstall them, but you may want to temporarily move them out of the way, e.g.

sudo mv /opt/local ~/macports

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

Unexpected .pc files: /usr/local/lib/pkgconfig/icu-i18n.pc /usr/local/lib/pkgconfig/icu-io.pc /usr/local/lib/pkgconfig/icu-le.pc /usr/local/lib/pkgconfig/icu-lx.pc /usr/local/lib/pkgconfig/icu-uc.pc

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: 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:

scala 

Warning: Homebrew's sbin was not found in your PATH but you have installed formulae that put executables in /usr/local/sbin. Consider setting the PATH for example like so echo export PATH="/usr/local/sbin:$PATH" >> ~/.bash_profile

Warning: You have a non-Homebrew 'pkg-config' in your PATH:
/opt/local/bin/pkg-config

./configure may have problems finding brew-installed packages using this other pkg-config.

napar zainstalować Scala daje:

Warning: It appears you have MacPorts or Fink installed. Software installed with other package managers causes known problems for Homebrew. If a formula fails to build, uninstall MacPorts/Fink and try again. Warning: scala-2.10.3 already installed, it's just not linked

Answer 1

Instalacja poszło dobrze, to po prostu nie jest zapewnienie dowiązania symbolicznego do /usr/local/bin, bo to „bój” o aprowizacji z DarwinPorts .

Jak mówi w komunikacie lekarza, najpierw zmienić uprawnienia w /usr/local/etc:

chown <username> /usr/local/etc 

prawdopodobnie ze sudo poprzedzany (sudo chown <username> /usr/local/etc).

Teraz napar może aktualizować niezbędne pliki i łącza Scala:

brew link scala 

i może być w porządku.
