我安装jsonpath一直失败，提示如下

Collecting 0.82
??Using cached jsonpath-0.82.tar.gz (9.6 kB)
??Preparing metadata (setup.py): started
??Preparing metadata (setup.py): finished with status ‘error’

??ERROR: Error [WinError 2] 系统找不到指定的文件。 while executing command python setup.py egg_info
ERROR: Could not install packages due to an OSError: [WinError 2] 系统找不到指定的文件。

求大神解答，有果！
