anaconda - Spyder 5 无法启动

Question

我刚刚下载了 Spyder 5 使用

conda upgrade anaconda
conda install spyder=5.0.0

但是，安装后，当我从 Windows 菜单启动 Spyder 时，我看到一个弹出窗口，表明 Spyder 5 正在启动。但是，几秒钟后弹出窗口消失并且 Spyder 不会启动。
当我尝试从 Anaconda Navigator 启动 Spyder 时，出现以下错误:

我已经尝试了以下事情(未成功):

卸载(通过 Windows 菜单)Spyder 并在 Anaconda 提示符下重新安装

再次安装 Spyder 4 conda install spyder=4.0.0 .但是，这也不再启动。

我该怎么做才能再次启动 Spyder？

Answer 1

我遇到了同样的问题，我只是使用 Uninstall-Anaconda.exe 完全卸载了 anaconda 3，然后我重新安装并再次更新了所有内容。这对你来说可能不是一个真正可行的选择，但我确实让它起作用了。
