Spyder 5不会在Windows 10上启动

Question

我刚刚将Python环境迁移到一台新的笔记本电脑上，在启动Spider 5时遇到了问题。我正在使用Python 3.7，并尝试通过Anaconda Navigator和命令提示符启动。以下是我得到的错误：

我如何解决这个问题

Answer 1

（Spyder maintainer here）该错误消息是由Spyder中的错误引起的，将在我们即将发布的下一个版本（5.0.1）中修复

目前唯一的解决方法是打开Anaconda提示符（或系统终端，如Windows上的cmd.exe，macOS上的Terminal，或Linux上的xterm），然后在那里运行：
