从用户定义的环境启动时，为什么 Spyder 5.0.0 应用程序启动错误？

Question

我将所有环境的 Spyder 升级到 5.0.0。当我从基本环境启动它时它启动时没有错误，但当我尝试从其他环境启动它时会产生应用程序启动错误。错误如下-

Answer 1

（此处是 Spyder 维护者）要解决此问题，您需要在您的环境中安装 QtAwesome 软件包的 1.0.2 版本。

您可以通过打开 Anaconda Prompt 并运行以下命令来做到这一点：

conda activate KB
conda install qtawesome=1.0.2

注意：对于 4 月 16 日发布且很快将成为 Anaconda 一部分的 Spyder 5.0.1，无需执行此操作。
