像许多其他人一样,我在安装 python 库时遇到问题(作为 tar 下载,然后解压缩)。

clang: note: this will be a hard error (cannot be downgraded to a warning) in the future

正如其他地方所建议的那样,我尝试输入终端“ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future sudo python setup.py install”,但没有成功。

有没有办法解决这个问题似乎出现在 xcode 5.1 中?

在构建之前,在 shell 中运行这两行:

export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments

这些导出告诉编译器忽略未使用的参数,而不是抱怨它们。


原因似乎是 Python 正在使用构建它的选项编译模块,除了其中一个选项不再适用于小牛:

clang 3.4 Apple 将默认设置为在未知标志上出错,但 CPython 使用与最初编译时相同的一组标志来构建模块。

对我来说,问题是我刚刚升级了 XCode,需要安装命令行工具(参见这个答案)。

运行xcode-select --install我的python库后安装得很好。

安装(在您下拉的程序文件夹内)

sudo -E python setup.py install

完成了任务!
