python -v 打印出垃圾[关闭]

Question

看起来python运行得很好……

$ python
Python 2.7.8 (default, Aug 24 2014, 21:26:19)
[GCC 4.2.1 Compatible Apple LLVM 5.1 (clang-503.0.40)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

但是 python -v 会打印出各种垃圾：

$ 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

如果您想要版本，请使用python -V（大写V）或python --version。

Answer 2

这不是垃圾，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。

您将从任何操作系统中的任何解释器获得一组类似的堆栈信息。

从通过运行 -h 提供的帮助菜单中：

v：详细（跟踪导入语句）；也可以多次提供 PYTHONVERBOSE=x 以增加详细程度

Answer 3

只需键入 python --version 你不会看到它。
