Question

我在安装gensim模块时遇到问题。我成功安装了numpy和scipy依赖模块，但在安装gensim时遇到错误。我尝试了Python pip install gives "Command "python setup.py egg_info" failed with error code 1"中给出的解决方案但他们都没有工作。

这是错误：

    >pip install --target="D:\python\packages" gensim
Collecting gensim
  Using cached gensim-2.3.0-cp36-cp36m-win32.whl
Collecting scipy>=0.18.1 (from gensim)
  Using cached scipy-0.19.1.tar.gz
    Complete output from command python setup.py egg_info:

Answer 1

您提供的错误文本表明实际问题是（a）涉及尝试安装scipy，gensim依赖该文本; （b）与断开的HTTPS连接有关，表明网络连接存在问题（或阻止安全连接的问题）。

此外，很少需要为--target指定pip;如果您的环境（可访问的可执行文件）设置正确，您就可以pip install gensim。（如果您要安装到非默认位置，当您的活动环境未使用您期望的库时，您可能会遇到问题。）

建议：

检查您是否能够访问远程安全网站，例如pip正在使用的PyPI存储库的主页：https://pypi.python.org/pypi
稍后再试;也许网络问题是暂时的
只试用pip install scipy
考虑使用conda分发工具，该工具往往针对Windows安装进行了优化。（我通常更喜欢miniconda变体，它只安装您请求的最少的一组内容。）

此外，虽然Python，gensim和相关软件包可以在Windows系统上运行，但请注意，此类Python / NLP / ML开源上的大多数开发/测试都发生在Linux / OSX系统上。因此，在Windows上经常会出现额外的安装/配置问题，然后通常较少的事先记录的故障排除来自之前遇到过同样问题的人。因此，如果您有选择，这种工作在Linux / Unix系统上通常会变得非常顺畅。

Answer 2

你可以通过两种方式安装genism： 1. pip install -U genism

2.install easy_install 那么

easy_install https://pypi.python.org/packages/source/s/setuptools/setuptools-19.2.tar.gz

无法在python中安装gensim
