推荐答案

可能导致这种情况的一个原因是，如果您单击控制台窗口以开始选择文本，换句话说，第一步从控制台窗口中复制文本.发生这种情况时，对控制台窗口的写入将挂起，直到您返回控制台窗口并按 Enter 删除选择框.

One thing that can cause this, is if you click on the console window in such a way that it starts to select text, in other words, the first step in copying text out of the console window. When this happens, a write to the console window will hang until you return to the console window and press Enter to remove the selection box.
