這裏主要解析安裝anaconda3-5.01，清華鏡像，wordcloud時的報錯記錄
本作者電腦情況：操作系統Ubuntu14.04
開始的時候嘗試用pyenv下載anaconda
pxh@pxh:~$ pyenv install anaconda3-5.0.1
Downloading Anaconda3-5.0.1-Linux-x86_64.sh...
-> https://repo.continuum.io/archive/Anaconda3-5.0.1-Linux-x86_64.sh

上網翻了個遍，沒有辦法解決，後來就改用如下方法安裝anaconda
輸入命令
wget https://repo.continuum.io/archive/Anaconda3-5.1.0-Linux-x86_64.sh
bash Anaconda3-5.1.0-Linux-x86_64.sh 這裏要注意不要以管理員的身份去下載，後果很嚴重
執行完上面兩條命令後會進入安裝界面
注意下面2處不要回車用缺省的選項：
Do you accept the license terms? [yes|no]
[no] >>> yes
Do you wish the installer to prepend the Anaconda3 install location
to PATH in your /home/ai/.bashrc ? [yes|no]
[no] >>> yes
Do you wish to proceed with the installation of Microsoft VSCode? [yes|no]
>>> no最後驗證anaconda安裝是否成功
$ cd
$ . ./.bash_profile
$ python
[ai@AIDevEnv ~]$ python
Python 3.6.4 |Anaconda, Inc.| (default, Jan 16 2018, 18:10:19)
[GCC 7.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
用exit()命令退出python
>>> exit()
上面是安裝anaconda，以下是安裝清華鏡像
插一句：或許會有人問爲什麼要安裝清華鏡像，原因很簡單，你直接用conda來下載wordcloud包是用外網來下載的，很慢，網有時會斷，清華鏡像可以幫助減少下載時間 ---這只是個人想法，不知道對不對，反正這個坑我掉過
pxh@pxh:~$ conda install wordcloud運行報錯
