我在 Python 2.7 上，我正在尝试使用 NLTK 词性标注器，它会生成此错误，因为我没有安装 numpy:
> Traceback (most recent call last):

resource_val = pickle.load(_open(resource_url))
ImportError: No module named numpy.core.multiarray
所以我从 here 下载了 numpy 1.7.0 ，将 cd 放入我的下载文件夹并安装 python setup.py 并出现此错误:

raise RuntimeError("Broken toolchain: cannot link a simple C program")
RuntimeError: Broken toolchain: cannot link a simple C program
然后我尝试使用 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。我不知道这里发生了什么。 numpy 版本是否与 python 2.7 或 NLTK 不兼容？
最佳答案
该模块依赖于一个有效的 C 构建链。这取决于您的系统如何安装它，谷歌会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，您将安装它和 python 头文件(根据评论编辑):
sudo apt-get install build-essential python-dev
