在ubuntu 10.10上安装herouku

我在尝试安装heroku时遇到以下错误

arun@laptop:~/apps/pm$ sudo gem install heroku
Building native extensions.  This could take a while...
ERROR:  Error installing heroku:
    ERROR: Failed to build gem native extension.

/usr/bin/ruby1.8 extconf.rb

    from extconf.rb:1


Gem files will remain installed in /var/lib/gems/1.8/gems/json-1.4.6 for inspection.

看起来很像

这件事已经解决了

sudo apt-get install ruby1.8-dev

我可以安装heroku。。但heroku命令都不起作用。“heroku:command not found”您需要将其添加到路径中才能运行它。在我的例子中，它位于/var/lib/gems/1.8/bini中，可以安装heroku。。但heroku命令都不起作用。“heroku:command not found”您需要将其添加到路径中才能运行它。在我的例子中，它位于/var/lib/gems/1.8/bin中
