Mac OSX Mountain Lion上的GCC-4.2错误，无法安装mysql-python [英] GCC-4.2 error on Mac OSX Mountain Lion, unable to install mysql-python

问题描述

我在Mac OSX Mountain Lion上构建MySQLdb时遇到问题。从OSX Lion升级到OSX Mountain Lion后，我也下载并安装了Xcode 4.4。然后，我进入了首选项>下载Xcode并安装了命令行工具。

我已经下载了MySQL-python版本。 1.2.3来自 http://sourceforge.net/projects/mysql-python/

当我运行

  python setup.py build 
  

我得到以下讯息：

 运行build 
运行build_py 
复制MySQLdb / release.py  - > build / lib.macosx-10.6-intel-2.7 / MySQLdb 
正在运行build_ext

无法执行gcc-4.2：没有这样的文件或目录
错误：命令'gcc-4.2'失败，退出状态1 
  

但是，gcc存在。当我运行

  gcc 
  

我得到

  i686-apple-darwin11-llvm-gcc-4.2：没有输入文件
  

以下是我发现的一个类似问题，但它的解决方案正是我已经完成的工作， 't为我工作。

如何在Mountain Lion上安装MySQLdb

解决方案

我在使用Ruby时遇到类似的问题在Rails 3.2.7上。
我也将系统升级到Mountain Lion，安装了Xcode 4.4.1并下载了命令行工具。

在命令行中，我收到一条错误消息说这是不可能找到文件： /usr/bin/gcc-4.2 （我现在无法粘贴精确的输出，我很抱歉） p>

我有一个 / usr / bin / gcc ，它的版本是 i686-apple- darwin11-llvm-gcc-4.2（GCC）4.2.1

我解决了这个问题， Ruby脚本的名字是：

  sudo ln -s / usr / bin / gcc / usr / bin / gcc- 4.2 
  

之后，一切正常。

I'm having trouble building MySQLdb on Mac OSX Mountain Lion. After upgrading to OSX Mountain Lion from OSX Lion, I have downloaded and installed Xcode 4.4 also. Then, I went to Preference > Downloads of the Xcode and installed Command Line Tools.

I've downloaded MySQL-python ver. 1.2.3 from http://sourceforge.net/projects/mysql-python/

When I run

python setup.py build

I get below message:

However, the gcc exists. When I run

gcc

I get

i686-apple-darwin11-llvm-gcc-4.2: no input files

Below is a similar question that I have found but its solution, which is exactly what I have done already, doesn't work for me.

How to install MySQLdb on Mountain Lion

解决方案

I've had a similar problem while working with Ruby On Rails 3.2.7. I too had upgraded the system to Mountain Lion, installed Xcode 4.4.1 and downloaded the Command Line Tools.

On the command line I got an error message saying it was impossible to find the file: /usr/bin/gcc-4.2 (I can't paste the precise output right now, I'm sorry).

I did have a /usr/bin/gcc and its version was i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1

I solved the problem by symlinking the file in the same directory and giving it the name the Ruby script was looking for:

sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2

After that, everything worked fine.
