Spyder 未从 Anaconda 环境之一启动

【中文标题】Spyder 未从 Anaconda 环境之一启动

【英文标题】：Spyder not launching from one of the Anaconda environments

【发布时间】：2020-08-16 21:09:01

【问题描述】：

我是新手。我已经开始使用 Python 学习 OpenCV，并按照课程说明成功创建了一个 Anaconda 环境，我可以从中轻松导入 CV2 并执行我的课程。到目前为止，我在使用这种环境时没有遇到任何问题。

现在，我想开始使用 Spyder，它可以从默认/基本环境很好地启动，但不能从我创建的“opencv-course”环境启动。相比之下，Jupyter Labs 和 Notebooks 在这两种环境中都能很好地启动。

我尝试在启动 Anaconda 时使用管理员权限卸载/重新安装 Spyder，但无济于事。

有人可以提出建议吗？

非常感谢！ 医学博士

显示以下错误信息：

【参考方案1】：

在此处查看此答案后： Spyder failed to launch in Anaconda after update (4.1.2)

我通过将 Pylint 的版本从 2.5 降级到 2.4.4 解决了这个问题。现在可以正常使用了。

非常感谢！ 医学博士
