ubuntu - 无法使用 Ubuntu16.04 和 anaconda 安装 gensim

Question

我正在尝试安装 python 包 (gensim)，但没有成功。

System details:
I am using Python 3.6.0 :: Anaconda custom (64-bit) with Ubuntu16.04LTS.

1. 首先，我按照 here 的指示进行操作(包括尝试安装前的更新)，我输入了

   easy_install --upgrade gensim
   

   并得到以下错误消息:

   Searching for gensim
   Reading https://pypi.python.org/simple/gensim/
   Download error on https://pypi.python.org/simple/gensim/: unknown urltype: https -- Some packages may not be found!
   Couldn't find index page for 'gensim' (maybe misspelled?)
   Scanning index of all packages (this may take a while)
   Reading https://pypi.python.org/simple/
   Download error on https://pypi.python.org/simple/: unknown url type:https -- Some packages may not be found!
   No local packages or working download links found for gensim 
   error: Could not find suitable distribution for 
   Requirement.parse('gensim')
   

2. 当我尝试使用 anaconda 安装时，

   conda install -c anaconda gensim=1.0.1
   

   描述here , 我得到了

   Fetching package metadata ...
   CondaHTTPError: HTTP None None for url 
   <https://conda.anaconda.org/anaconda/linux-64/repodata.json>
   Elapsed: None
   
   An HTTP error occurred when trying to retrieve this URL.
   HTTP errors are often intermittent, and a simple retry will get you on your way.
   SSLError(SSLError("Can't connect to HTTPS URL because the SSL module is not available.",),)
   

3. 当我尝试直接从 git 安装时

   pip install https://github.com/RaRe-Technologies/gensim.git
   

   我遇到了类似的错误

   SSLError("Can't connect to HTTPS URL because the SSLpip._vendor.requests.packages.urllib3.exceptions.SSLError: 
   Can't connect to HTTPS URL because the SSL module is not available.
   

4. 我尝试通过使用来解决这个问题

   PYTHONUSERBASE=/home/usr/anaconda3 pip3 install --user --upgrade gensim
   

   它能够安装 gensim 包，但是在新创建的文件夹 /home/usr/anaconda3/python3.5 下，即使我的默认 python 是 python3.6

   <

结论(？):

来自 this我知道可能我的 Python 编译时没有支持 SSL，如果我解决了这个问题，我可能会赢得这场漫长的战斗。但我不明白如何解决这个问题 D_:

另外，我不明白为什么它在manual时坚持安装在python3.5下。说这个包也兼容python3.6。

首先你需要安装openssl:

sudo apt install openssl

然后，如果你从源代码安装了 python，你必须:

./configure
make
sudo checkinstall
