Robotframework“选择文件”导致 AttributeError: module 'base64' has no attribute 'encodestring' in docker

Question

我正在尝试在 docker 容器中运行测试，该容器在本地运行没有问题：我想从“正确”目录上传正确的.csv 文件

*** Keyword ***
Upload file
    [Arguments]    ${directory}    ${file}
    Choose File    ${choose_file_input}    ${EXECDIR}/Files/${directory}/${file}

** Test case ***
Upload
    Upload file    correct    correct.csv

但是，当在 docker 中运行测试时，我收到 AttributeError: module 'base64' has no attribute 'encodestring' 的失败。是因为docker中没有GUI吗？或者需要修复编码？或者最终也许还有另一种解决方案可以用来上传文件？

我们也遇到了这个问题，但由于与其他库不兼容，因此无法返回旧版本的 Python。如果您发现自己处于同一位置，可以重新创建别名，如下所示：

import base64
base64.encodestring = base64.encodebytes

无论你的切入点是什么。
