1.首次执行python_repos.py时API调用报错
url= 'http://api.github.com/search/repositories?q=language:python&sort=stars'
r = requests.get(url)
print("Status code:", r.status_code)
报错如下：

解决方法：安装requests的security extras：pip install -U requests[security]

2. 解决上述问题后，再执行脚本，画图报错：
Traceback (most recent call last):

File "/home/happy/.local/lib/python3.6/site-packages/pygal/_compat.py", line 61, in to_unicode
return string.decode('utf-8')
AttributeError: 'NoneType' object has no attribute 'decode'
解决方法：将
plot_dict = {
'value': repo_dict['stargazers_count'],
'label': repo_dict['description'],
'xlink': repo_dict['html_url'],
}
中的 'label': repo_dict['description'] 改为 'label': str(repo_dict['description'])
