Question

我收到一个错误 clang: error: unknown argument: '-fabi-version=2' 当我尝试使用 pip 安装 mysql-python 时。

MacBook-Pro-de-Haruan:MySQL-python-1.2.5 haruan$ sudo -E pip install MySQL-python

我已经用过：

export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
export ARCHFLAGS='-Wno-error=unused-command-line-argument-hard-error-in-future'

和

sudo -E ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future easy_install mysql-python

sudo -E ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip mysql-python

问题依然存在。

我的 Xcode 是 6.4 版 (6E35b) 我使用的是 Mac OS X Yosemite

Answer 1

我发现了问题，我安装了 XAMPP，XAMPP 的 mysql 使用了该标志。 我通过 Homebrew 卸载了 XAMPP 并安装了 mysql，现在一切正常。

Answer 2

如果其他人遇到此问题并且出于某种原因不想通过更改为不同的 MySQL 安装来解决它，有一个相对简单的解决方法。我在尝试针对 Bitnami MAMP 堆栈 5.5 版中包含的 MySQL 包编译 mysqlclient 时遇到了这个问题。您只需要调整安装，这样有问题的参数就不会传递给编译器，如下所示：

1. 从GitHub下载包
2. 打开 setup_posix.py 文件
3. extra_compile_args变量初始化后（当前版本第58-59行），添加以下代码行：extra_compile_args.pop(extra_compile_args.index('-fabi-version=2'))
4. 在包目录下，运行python setup.py install

为我工作。

Answer 3

我在使用 Softaculous AMPPS 时遇到了同样的问题。 根据 Max 的上述回复，我能够弄清楚如何解决这个问题。

只需从“cflags”中删除“-fabi-version=2”标志（在我的例子中为第 122 行）
