DataDriver 库方法 _stats_suite 失败：TypeError: 'encoding' is an invalid keyword argument for this function

Question

我正在尝试在 docker 映像上启动我的机器人代码。所以我已经安装了 python 3 和我需要的所有库（我希望）。 这是一个概述：

$ pip list

wheel                          0.32.3 

但是当我尝试启动机器人代码时，它在代码中执行的第一个调用是针对 DataDriver 库的，但它似乎失败了。 据我所知，该错误意味着它没有正确安装，但它在上面提到的列表中。 我收到的错误：

$ robot --outputdir output IPS/BCMC.robot

有什么建议吗？

编辑： 以下是 docker 镜像上 DataDriver 模块安装的痕迹：

Answer 1

尝试将我自己电脑上的库版本与图像上安装的版本匹配时出错。应该做的。 在我的 pip 安装中删除版本规范解决了这些问题。

Answer 2

你有没有尝试在导入库时更改编码参数？

*** Settings ***    
Library    DataDriver
    ...    encoding=cp1252

不知道哪个是正确的，但下面的链接有一个链接到其他选项。
