python-v打印垃圾

看起来python工作得很完美

$ python

但是python-v打印出各种各样的垃圾：

它不是垃圾，您正在以详细模式加载默认的python解释器，这些是它加载所需的依赖项

在任何操作系统中，您都可以从任何解释器获得类似的堆栈信息集

从通过运行-h提供的帮助菜单：

v：详细（跟踪导入语句）；此外，可以多次提供PYTHONVERBOSE=x以增加详细性

---

如果您想要该版本，请使用

python-V

（大写

V

）或

python--version

只需键入python--version，您将看不到它

是什么使您认为这不是预期的输出？手册页输出的可能副本更有用：-v每次初始化模块时打印一条消息，显示加载模块的位置（文件名或内置模块）。如果给定两次，则在搜索模块时，为检查的每个文件打印一条消息。还提供了有关在退出时清理模块的信息。
