OS X Mountain Lion:gcc-4.2 没有这样的文件或目录 [英] OS X Mountain Lion: gcc-4.2 No such file or directory

问题描述

尝试在 Mountain Lion 上安装 gem 并且 make 找不到 gcc-4.2:

Tried to install a gem on Mountain Lion and make couldn't find gcc-4.2:

kamil$ gem install posix-spawn -v '0.3.6'
Building native extensions.  This could take a while...
ERROR:  Error installing posix-spawn:
    ERROR: Failed to build gem native extension.

        /Users/kamil/.rbenv/versions/1.9.3-p0/bin/ruby extconf.rb
creating Makefile

make
compiling posix-spawn.c
make: gcc-4.2: No such file or directory
make: *** [posix-spawn.o] Error 1

推荐答案

如果你安装了 Xcode，gcc 应该是可用的.检查它在哪里:

If you have Xcode installed, gcc should be available. Check where it is with:

kamil$ which gcc
/usr/bin/gcc

然后创建一个从 gcc-4.2 到普通 gcc 的用户级符号链接:

Then make a user-land symbolic link from gcc-4.2 to plain gcc:

kamil$ sudo ln -s ~/bin/gcc /usr/bin/gcc-4.2

(通过 .bash_profile 或 中的 export PATH=...:$HOME/bin 确保用户域绑定文件夹位于您的路径中.zshrc.)

(Ensure the user-land bind folder is in your path via export PATH=...:$HOME/bin in your .bash_profile or .zshrc.)

Gem 之后安装正常.

Gem installed fine afterwards.
