安装python库时,"'cc'以退出状态1失败"错误

Question

像许多其他人一样,我在安装python库时遇到问题(下载为tar,然后提取).

clang: note: this will be a hard error (cannot be downgraded to a warning) in the future
error: command 'cc' failed with exit status 1

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

有没有解决这个问题似乎与xcode 5.1一起出现的问题？

Answer 1

在构建之前在shell中运行以下两行:

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正在使用它构建的选项编译模块,除了其中一个选项不再适用于小牛队:

clang 3.4 Apple默认为未知标志出错,但CPython使用最初编译的同一组标志构建模块.

很多人都遇到了这个问题:

• Ansible安装-clang:错误:未知参数:' - mno-fused-madd'
• 无法在Mac Mavericks上安装python mysql库
• clang错误:未知参数:'-mno-fused-madd'(python包安装失败)

Answer 2

对我来说问题是我刚刚升级了XCode并需要安装命令行工具(请参阅此答案).

运行xcode-select --install我的python库安装好了.

Answer 3

安装(在你拉下的程序文件夹内)

sudo -E python setup.py install

做了这个工作!
