mac os gem安装json出现error failed的解决办法
升级到最新的mac os Mavericks。装json出现错误:
代码如下:
gem install json -v '1.8.1' Building native extensions. This could take a while... ERROR: Error installing json: ERROR: Failed to build gem native extension. /usr/local/var/rbenv/versions/2.0.0-p247/bin/ruby extconf.rb creating Makefile make "DESTDIR=" compiling generator.c In file included from /usr/local/var/rbenv/versions/2.0.0-p247/include/ruby-2.0.0/ruby.h:33, from ../fbuffer/fbuffer.h:5, from generator.c:1: /usr/local/var/rbenv/versions/2.0.0-p247/include/ruby-2.0.0/ruby/ruby.h:51:21: error: string.h: No such file or directory /usr/local/var/rbenv/versions/2.0.0-p247/include/ruby-2.0.0/ruby/ruby.h:61:21: error: stdint.h: No such file or directory /usr/local/var/rbenv/versions/2.0.0-p247/include/ruby-2.0.0/ruby/ruby.h:64:23: error: inttypes.h: No such file or directory /usr/local/var/rbenv/versions/2.0.0-p247/include/ruby-2.0.0/ruby/ruby.h:68:19: error: stdio.h: No such file or directory
解决办法:
代码如下:
xcode-select --install
需要重新安装Command Line Developer Tools
如果这个办法还是不行,mac下需要安装下apple-gcc42
代码如下:
brew install apple-gcc42
注意brew 0.9.4应该是不带apple-gcc42的源的,可以使用brew doctor检查下是否和Mavericks兼容,这里需要升级
代码如下:
brew update
