If it's not defined in your code, you need to import it. This is exactly the same as anyname in Python; you can't use something until you have defined it.
如果它没有在你的代码中定义，你需要导入它。这与Python 中的任何名称完全相同；在你定义它之前你不能使用它。
import json

Use the command as simplejson instead of json like below,
使用命令作为 simplejson 而不是像下面这样的 json，
pip install simplejson
pip 安装 simplejson
If the above command also throwing an error Use the following command
如果上面的命令也抛出错误使用下面的命令
easy_install simplejson
easy_install simplejson
easy_install works sometimes if pip cannot serve the request.
如果 pip 无法满足请求，easy_install 有时会起作用。
