在linux下不能显示中文

[Deleted user]

在linux下，生成的图片的字体和大小无法改变，即使在Option里指定textStyle样式也不行。求解决方法

@siukimfong
请更新下node-echarts

中文无法显示是因为node-canvas库缺乏相应的字体，node-canvas某一分支提供了加入字体的api,下面是解决办法
1.git clone https://github.com/chearon/node-canvas.git ,然后进入到clone的项目目录，执行npm install

2.下载所需要的字体

3.具体代码如下：

var node_echarts = require('node-echarts');
var path = require('path');
var Canvas =require('./node-canvas');
Canvas.registerFont(path.join(__dirname, "华文仿宋.ttf"), { family: "华文仿宋"});
node_echarts({
canvas: Canvas,
font: '12px 华文仿宋',
path: __dirname + '/中文字体demo.png',
option: option,
width: 1000,
height: 500
})

可查看demo下中文字体demo.js

感谢回复，新安装的canvas支持新的字体注册api了，但是node-echarts依然无法改变字体和字号。
我尝试只使用canvas来生成含有字符的图片，是成功的，一旦和echarts结合起来，就无法改变字体和字号了

@siukimfong 你好，请问我在安装node-echarts时总是报错，你有遇过么
以下是错误日志：

@siukimfong maybe you can set the textStyle option in echarts options, such as:

textStyle: {
   fontFamily: '华文仿宋',
   fontSize: 12,
},
title: {
    text: '堆叠区域图'
},
