Watchdog: 命令“gcc-4.2”失败，退出状态为 1

我遇到了同样的问题，另外尝试使用 pip install 为 python2 和 3 构建失败：

我得到了手动 setup.py 以使用以下命令：

CC=/usr/bin/gcc python3 setup.py install

使用命令“ls -l /usr/bin/gcc*”找到标志路径，该命令返回：

-rwxr-xr-x 1 根轮 14160 2014 年 9 月 29 日 /usr/bin/gcc
-rwxr-xr-x 1 MLR 轮 166128 2011 年 2 月 11 日 /usr/bin/gcc-4.2

我只是指定它使用另一个，因为 gcc-4.2 一直失败。 不确定这是否适用于原始海报，但这是我的解决方案。

CC=/usr/bin/gcc pip install也对我有用。

做ls -l /usr/bin/gcc*回报

$ ls -l /usr/bin/gcc*
lrwxr-xr-x  1 root  wheel       7 30 Dec 16:16 /usr/bin/gcc -> gcc-4.2
-rwxr-xr-x  1 root  wheel   97392 19 May  2009 /usr/bin/gcc-4.0
-rwxr-xr-x  1 root  wheel  166128 19 May  2009 /usr/bin/gcc-4.2

指定 gcc 或 gcc-4.0 对我不起作用，并给了我这个：

...看起来与上面发布的错误非常相似

在我的例子中， gcc-4.2指向/usr/local/bin/gcc-4.2 ，它是 Homebrew 安装的 gcc。 我可以使用/usr/bin/gcc构建看门狗，它是 Apple 的 LLVM Clang。 这似乎是一个路径冲突问题。 谢谢。

请注意，该问题也应使用 #467 修复。
