错误

编码错误

SyntaxError: Non-ASCII character '\xe6' in file 打印日期.py on line 1, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

Python在默认状态下不支持源文件中的编码。解决方案有如下三种：

一、在文件头部添加如下注释码：

coding=<encoding name> 例如，可添加# coding=utf-8

二、在文件头部添加如下两行注释码：

#!/usr/bin/python

# -*- coding: <encoding name> -*- 例如，可添加# -*- coding: utf-8 -*-

# python3中默认使用 utf-8编码

三、在文件头部添加如下两行注释码：

#!/usr/bin/python

# vim: set fileencoding=<encoding name> : 例如，可添加# vim: set fileencoding=utf-8 :

python 花图工具

Matplotlib 和 pyecharts

pyecharts==0.5.11
pyecharts-javascripthon==0.0.6
pyecharts-jupyter-installer==0.0.3
pyecharts-snapshot==0.1.10

如果提示 没有module jiaji2的时候，设置下环境变量

执行命令，查看对应的地址，把地址加到环境变量中

pip install jiaji2

进入.bashrc

export PYTHONPATH=$PYTHONPATH:"/usr/local/lib/python3.6/site-packages"

source .bashrc

它的安装过程中要去 github 下载一个包，而 github release 文件放在亚马逊 aws 上（被墙了）。解决方法是借助淘宝镜像 (http://cnpmjs.org/downloads https://npm.taobao.org/mirrors/phantomjs/) 安装，输入以下命令:

PHANTOMJS_CDNURL=https://npm.taobao.org/mirrors/phantomjs/ npm install phantomjs-prebuilt

https://github.com/xhlwill/blog/issues/11

如果提示"No phantomjs found in your PATH. Please install it!则" 保存图片需要安装

npm install -g phantomjs-prebuilt

如果报错安装下面命令

npm install phantomjs-prebuilt@2.1.14 --ignore-scripts

centos 7

python(>=2.7)
requests==2.18.4
mysql-connector==2.2.9
pyecharts==0.5.11

保存图片需要安装phantomjs-prebuilt
下载地址http://www.bzip.org/downloads.html

安装bzip2

yum -y install bzip2

解压工具包

tar -xjvf phantomjs-2.1.1-linux-x86_64.tar.bz2

设置环境变量，打开~/.bashrc添加

export PATH=$PYTHON/bin:$PHANTOMJS/bin:$PATH

退出并保存

source .bashrc
