问题
无法使用conda进行安装第三方包
mrlevo@mrlevo-Lenovo:~$ conda install folium
Fetching package metadata …
CondaHTTPError: HTTP None None for url https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/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.
ConnectionError(MaxRetryError(‘HTTPSConnectionPool(host=\’mirrors.tuna.tsinghua.edu.cn\’, port=443): Max retries exceeded with url: /anaconda/pkgs/free/ladTimeoutError (“HTTPSConnectionPool(host=\’mirrors.tuna.tsinghua.edu.cn\’, port=443): Read timed out. (read timeout=9.15)”,))’,),)
解决方案1
修改其包管理镜像为国内源，简单来说，就是在终端运行这两句话
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --set show_channel_urls yes
然后再试试，如果不行，我想了个终极解决方案。
解决方案2
当然首先保证你的pip可用，如果pip都不行，你该检查下网络了。正题，简单说，就是pip安装包之后，把包拷贝到anaconda的包路径下，哈哈哈，因为包根本没有编译的过程(对于不需要编译的包)
# 步骤一：找到包依赖的所有包
$ pip install folium # 前提是我已经装了一次了
Requirement already satisfied: folium in /usr/local/lib/python2.7/dist-packages
Requirement already satisfied: Jinja2 in /usr/local/lib/python2.7/dist-packages (from folium)
Requirement already satisfied: six in /usr/local/lib/python2.7/dist-packages (from folium)
Requirement already satisfied: branca in /usr/local/lib/python2.7/dist-packages (from folium)
Requirement already satisfied: MarkupSafe>=0.23 in /usr/local/lib/python2.7/dist-packages (from Jinja2->folium)
# 从这里可以看出folium依赖什么包，路径都在哪
# 步骤二，找到anaconda包的安装路径
mrlevo@mrlevo-Lenovo:~$ python

>>> import pandas
pandas.__file__
>>> pandas.__file__
'/home/mrlevo/anaconda2/lib/python2.7/site-packages/pandas/__init__.pyc'
# 可以看出，包都在/home/mrlevo/anaconda2/lib/python2.7/site-packages/ 路径下，哈哈哈，开始第三步
# 步骤三，复制pip的包到anaconda包的路径下
mrlevo@mrlevo-Lenovo:~$ cp -r /usr/local/lib/python2.7/dist-packages/folium /home/mrlevo/anaconda2/lib/python2.7/site-packages/folium
# 注意这一步需要把所有与folium依赖的包都复制进来，当然anaconda有的不用复制
之后再进入python环境，import folium看看是不是可行了。
