我剛買了一臺新的MacBook Pro(顯然是w/ML)。我正在做的第一件事是安裝開發工具。我用rvm安裝了Ruby,並且還安裝了Homebrew。我不得不下載XCode命令行工具。在山獅創建寶石時出錯
$ gcc -v
Using built-in specs.

我能夠安裝mongo
寶石很好,但是當我嘗試安裝nokogiri
,我收到以下錯誤:
$ gem install nokogiri
Building native extensions. This could take a while...
ERROR: Error installing nokogiri:
ERROR: Failed to build gem native extension.
/Users/johnsmith/.rvm/rubies/ruby-1.9.3-p327/bin/ruby extconf.rb
checking for libxml/parser.h... *** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
該消息後,它會列出一大堆的配置選項,然後說:
/Users/johnsmith/.rvm/rubies/ruby-1.9.3-p327/lib/ruby/1.9.1/mkmf.rb:369:in `try_do': The compiler failed to generate an executable file. (RuntimeError)
You have to install development tools first.
看來我有開發工具,所以我找不出這個問題。有什麼想法嗎?
謝謝。我在Nokogiri網站上找到了安裝Homebrew 0.9的說明,但仍然遇到同樣的錯誤。也許Homebrew 0.9.3打破了別的東西。我會接下來嘗試MacPorts。 –
