为什么在使用 pip (Windows 10) 安装插件后看不到 spyder-terminal?

Why can't I see spyder-terminal after installing plugin using pip (Windows 10)?

我在 Windows 10 (x64) 机器上使用 Python 3.9.0 和 Spyder 4.2.0。通过官方 repo,我使用 pip 安装了 spyder-terminal 插件。它安装成功。安装后,当我打开 Spyder IDE 时,我看不到终端。我尝试深入研究 View>PanesPreferences,但没有看到关于 enabling/checking spyder-terminal 的任何提示?

是否有人遇到过同样的问题并且有建议的解决方法?我是否遗漏了一些依赖项?

这是 pip list 的输出:

单击视图 => 窗格 => IPython 控制台。 Ipython 控制台应该会在右下角打开

我发现 Spyder 插件 spyder-terminal 和 spyder-notebook 兼容 Python 3.7 而不是 Python 3.9。
