Python robot框架库JSONlibrary导入错误

我在导入JSONlibrary时遇到问题，我不确定它在哪里失败。 我得到以下错误：

[ ERROR ] Error in file 'C:\Users\path\to\file.robot' on line 12: Importing test library 'JSONLibrary' failed: SyntaxError: no viable alternative at input 'from' (__init__.py, line 1367)
Traceback (most recent call last):

您是否可以用更精确的python和软件包版本更新这个问题

python--version

，

robot--version

和

pip-list

。我想那会很有帮助。用Listed更新版本。也许你可以尝试更新你的pip。奇怪的事情以前发生过<代码>pip安装--升级pip
