尝试安装scala时Mac OS Mavericks中的自制错误

Question

我刚安装了Mavericks，我尝试安装了Scala语言，但尝试了brew install scala，但失败了。 然后我输入brew update，但仍然安装scala失败。 所以我张贴brew doctor命令来帮助读者的stackoverflow帮助我解决这个问题。 下面是结果：

$ 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.

酿造安装斯卡拉给出：

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

安装了罚款，它只是没有提供一个符号链接/usr/local/bin，因为它是“害怕”与MacPorts的时间浪费。

因为它在医生有消息称，首先更改/usr/local/etc权限：

chown <username> /usr/local/etc 

可能与sudo前缀（sudo chown <username> /usr/local/etc）。

现在BREW可以更新必要的文件和链接阶：

brew link scala 

，你可能会被罚款。
