Mac OSX Mountain Lion 上安裝 postgres gems 問題

+ 2 個回應
替 mac 上了 Mountain Lion,然後想在上面繼續 ruby on rails development,可是在行 bundle install 時出現安裝不了 pg 的訊息:

Installing pg (0.13.2) with native extensions 
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

        /Users/ryan/.rvm/rubies/ruby-1.9.2-p290/bin/ruby extconf.rb 
checking for pg_config... no
No pg_config... trying anyway. If building fails, please try again with
 --with-pg-config=/path/to/pg_config
checking for libpq-fe.h... no
Can't find the 'libpq-fe.h header
*** 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.

Provided configuration options:
    --with-opt-dir
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include

    --without-pg-lib=${pg-dir}/lib
    --with-pg-config
    --without-pg-config
    --with-pg_config
    --without-pg_config


Gem files will remain installed in /Users/ryan/.rvm/gems/ruby-1.9.2-p290/gems/pg-0.13.2 for inspection.
Results logged to /Users/ryan/.rvm/gems/ruby-1.9.2-p290/gems/pg-0.13.2/ext/gem_make.out
An error occured while installing pg (0.13.2), and Bundler cannot continue.
Make sure that `gem install pg -v '0.13.2'` succeeds before bundling.

以為因為沒有裝 postgresql,誰知用 homebrew 安裝 postgresql 後情況沒有任何改善。在網上找了很久,就算裝了 xcode 和 command line for xcode也不行。費了一天後,終於找到解決方法。

原來要裝這個 gcc installer,裝了後便可以用
gem install pg
裝 posgresql gems !

They are primarily based in Sydney and have developed the Megaways engine. Because Megaways was an enormous success, they licensed the engine to different providers corresponding to Blueprint Gaming, iSoftBet, and NetEnt. Megaclusters, which additionally they personal, is expected to become as in style as Megaways. This means symbols that land on adjacent reels will nonetheless pay.
