Spyder 5 无法在 Windows 10 上启动

Question

我刚刚将我的 Python 环境迁移到一台新的笔记本电脑上，但无法启动 Spider 5。我使用的是 Python 3.7，并尝试通过 Anaconda Navigator 和命令提示符启动。这是我得到的错误：

我该如何解决这个问题？

Answer 1

（此处是 Spyder 维护者）该错误消息是由 Spyder 中的错误引起的，它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 Prompt（或系统终端，如 Windows 上的 cmd.exe、macOS 上的 Terminal 或 Linux 上的 xterm）并在那里运行：

spyder --reset
