无法在VS代码中加载Python REPL

Question

我使用的是Windows 10和Anaconda 5.1.0，Python 3.6 64位。

我使用默认的Anaconda安装程序安装了VS Code（在2/17/2018添加了功能）。然后，我尝试加载Python REPL（control + shift + P，然后是Python：Start REPL）。然而，什么都没发生;在下面的终端中，它只是Windows Powershell。

我还创建了以下python代码片段，它可以与F5或control + F5完美地运行。它应该表明我的Python设置是正确的。但是，我仍然无法使用Python REPL。

当我打开开发人员工具时，我看到了：
