如何在Mac OSX上安装PCRE开发标题 [英] How to Install PCRE Development Headers on Mac OSX

问题描述

我刚刚将MacBook Pro升级到Mavericks，而我的本地Ruby on Rails开发环境并没有立即运行，当我访问localhost时，我看到了It works!并记得我需要启动Phusion Passenger，所以当我运行passenger start，它检查所有先决条件，并且在到达PCRE开发标头时失败:

I just upgraded my MacBook Pro to Mavericks and my local Ruby on Rails development environment isn't running straight off the bat, when I visit localhost I see It works! and remembered I needed to start Phusion Passenger, so when I run passenger start it checks all the prerequisites and fails when it gets to the PCRE Development Headers:

 * Checking for PCRE development headers...
    Found: no

它告诉我要去 http://www.pcre.org/进行下载，所以我从此处下载的8.33文件中，该文件已保存到我的Downloads文件夹中，所以我将其解压缩，cd到该文件夹​​并运行:

It tells me to go to http://www.pcre.org/ to download them so I downloaded 8.33 from here which went to my Downloads folder, so I unzipped it, cd'd to the folder and ran:

./configure
make
make install

然后cd返回桌面上的我的rails应用程序目录，然后重新运行passenger start，但仍然相同.尝试了一个新的终端"窗口，但没有任何区别.

Then cd'd back to my rails app directory on my Desktop and re-ran passenger start but it's still the same. Tried a new Terminal window but that didn't make any difference.

我必须先完成此操作才能使我的开发环境正常工作，但这次似乎无法解决.

I must have done this before to get my dev environment working but can't seem to solve it this time.

我也尝试过brew install pcre，但是它说的是Warning: pcre-8.33 already installed.

I also tried brew install pcre but it says Warning: pcre-8.33 already installed.

推荐答案

重新安装OS X开发人员工具.小牛升级将它破坏了.

Reinstall the OS X Developer Tools. It was broken by the Mavericks upgrade.
