无法使用setup.py安装numpy

Question

我正在使用Python 2.7并且我正在尝试使用NLTK语音标记器,因为我没有安装numpy,因此会生成此错误:

> Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Python/2.7/site-packages/nltk/tag/__init__.py", line 99, in pos_tag
    tagger = load(_POS_TAGGER)
  File "/Library/Python/2.7/site-packages/nltk/data.py", line 605, in load
    resource_val = pickle.load(_open(resource_url))
ImportError: No module named numpy.core.multiarray

所以我从这里下载numpy 1.7.0,在我的下载文件夹中做了一个cd并做了python setup.py install并得到了这个错误:

然后我尝试用sudo pip install -U numpy安装它并获得相同的"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？

Answer 1

我遇到了同样的错误并通过更新 pip 修复了它。

pip install --upgrade pip

希望有帮助。

Answer 2

该模块依赖于有效的 C 构建链。这取决于您的系统如何安装它，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，您可以安装它和 python 头文件（按评论编辑）：

sudo apt-get install build-essential python-dev
