但是python -v打印出各种垃圾：

$ python -v

我用brew安装了所有东西。这是一个新的macbook pro，更新了Mavericks。

Answer 1

这不是垃圾，你是在详细模式下加载默认的python解释器，这些是加载所需的依赖项。

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。

通过运行-h：

提供的帮助菜单中的

v：verbose（trace import statements）;还可以多次提供PYTHONVERBOSE = x以增加详细程度

Answer 2

如果您希望版本使用python -V（使用大写V）或python --version。

Answer 3

只需键入python --version，你就不会看到它。

python -v打印出垃圾
