Question

我尝试升级使用MacOS High Sierra v 10.13.6失败的robotframework。然后，我尝试将其卸载以进行全新安装。当我尝试使用pip时，现在出现以下错误。我正在使用python 2.7.15和pip版本19.0.1。有关如何解决此问题的任何建议将不胜感激

Answer 1

似乎是与pip最新版本有关的问题：

有人通过从python site-packages目录中删除剩余数据来修复其系统：

C：\ Python27 \ Lib \ site-packages \ robot

在site-packages目录中也会有类似的内容，也应该删除：

./ robot-3.1.dist-info / METADATA

也许降级点数也可能有助于避免此问题，尽管我在票证中未提及该点。

卸载robotframework后，pip冻结引发错误
