用的官网第一个示例，结果网页打开是个空白页面

[rwfy2000]

环境：python3.6 pyecharts0.4.1 win7 64位

打开render.html，是个空白页面，各种浏览器试过一样，大神帮下吧。

[chenjiandongx]

pip uninstall pyecharts -> pip install pyecharts==0.4.1 -U 试试

[rwfy2000]

@chenjiandongx 试了pip uninstall pyecharts -> pip install pyecharts==0.4.1 -U ，还是一样空白。

[rwfy2000]

@chenjiandongx 打开ie浏览器打开render.html提示echarts未定义。
我的临时解决方法如下：
1、在echarts官网下载了echarts.js文件。
2、将echarts.js文件放在py文件同目录下。
3、render.html源码里引用echarts.js。
`

<script src="echarts.js"></script>
<script type="text/javascript">

var myChart_76714d7f61674454a1241b067fedbaa3 = echarts.init(document.getElementById('76714d7f61674454a1241b067fedbaa3'), null, {renderer: 'canvas'});`

但是我每次都要这样吗？好麻烦啊。

OK. In the same environment, please run your program and share you render.html here.

[rwfy2000]

@chfw 不允许上传html文件，我重命名为txt了。
render.txt

logging.basicConfig(

Please place above code before all of your sample code and then run it. Please show me the log file.

@chfw ，按你的写法，提示如下：

先卸载

pip uninstall jupyter-echarts-pypkg

再装，再试试。

pip install jupyter-echarts-pypkg

[rwfy2000]

@chfw 卸载后，再安装，发现安装的版本是0.1.1，不是原来的0.1.0

[rwfy2000]

@chfw 现在正常了，感谢不耐其烦的帮助！

[chfw]

In conclusion: jupyter-echarts-pypkg is not installed properly, although it appears to be so (pip freeze).

The following line produces empty output because no jupyter-echarts-pypkg found:

我运行官网的第一个例子，报这个错，应该怎么解决啊

Exception has occurred: FileNotFoundError
[Errno 2] No such file or directory: '/usr/local/lib/python3.6/dist-packages/jupyter_echarts_pypkg/resources/registry.json'

[FrebEaton]

重新安装 jupyter-echarts-pypkg库，终于解决了问题
