我正在使用Python 2.7而我正在尝试使用NLTK语音标记器，因为我没有安装numpy会产生此错误：

所以我从here下载了numpy 1.7.0，在我的下载文件夹中输入了cd并执行了python setup.py install并得到了这个错误：

raise RuntimeError("Broken toolchain: cannot link a simple C program")
RuntimeError: Broken toolchain: cannot link a simple C program
然后我尝试用sudo pip install -U numpy安装它并得到相同的“无法链接简单的C程序”错误。我无法弄清楚这里发生了什么。 numpy版本是否与python 2.7或NLTK不兼容？

该模块依赖于工作的C构建链。这取决于您的系统安装方式，谷歌将在这种情况下提供帮助。
你可以看到它正在寻找gcc：
sh: gcc-4.2: command not found
在基于Debian的linux上，你可以安装它和python标题（编辑每条评论）：
sudo apt-get install build-essential python-dev

最近我一直看到这个：
clang：错误：未知论点：＆＃39; -mno-fused-madd＆＃39; [-Wunused的命令行参数的硬错误功能于未来]
见这里修复：
clang error: unknown argument: '-mno-fused-madd' (python package installation failure)

我遇到了同样的错误并通过更新pip修复了它。
pip install --upgrade pip
希望它有所帮助。
答案 3 :(得分：1)
您需要安装gcc。
在CentOS上：
sudo yum install gcc
如果您看到以下错误，请尝试重新安装numpy：
Command python setup.py egg_info failed with error code 1 in /tmp/pip-build-root/numpy
执行命令
sudo yum install python-devel

也许不是你需要的，但如果你在安装numpy时遇到问题，我推荐“Pyzo”。它是一个python发行版，附带一组非常有趣的包，其中包括numpy。 www.pyzo.org
