编码库方法编码失败: TypeError：‘DataDriver’是此函数的无效关键字参数

Question

我正在尝试在docker镜像上启动我的机器人代码。所以我已经安装了python3和所有我需要的库(我希望如此)。以下是一个概述：

$ pip list
Package                        Version

SecretStorage                  2.3.1  
setuptools                     3.4

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对DataDriver库的调用，但似乎失败了。根据我所能找到的，这个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:这是DataDriver模块在docker镜像上的安装轨迹：

Answer 1

尝试将我自己pc上的库版本与安装在镜像上的版本进行匹配时出错。我应该这么做的。删除我的pip安装中的版本规范修复了这个问题。

Answer 2

您是否尝试过在导入库时更改编码参数？

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

不知道哪一个是正确的，但是下面的链接有一个指向其他选项的链接。
