Question

我最近通过运行安装程序并更改环境变量来安装Python 3.4.4。我还尝试了一些简单的命令来查看它是否已正确安装。但是，当我在命令行中输入python -v时，这就是我得到的：

tel)] on win32

或者，当我输入python -version时，这就是我得到的：

Unknown option: -e
usage: python [option] ... [-c cmd | -m mod | file | -] [arg] ...
Try `python -h' for more information.

所以我不确定是否有任何错误安装的部件导致了这些。希望有人可以提供帮助。

您的安装没问题，-v命令行选项不代表版本。

-v每次初始化模块时打印一条消息，显示模板加载它的位置（文件名或内置模块）。给出两次后，为每个检查的文件打印一条消息用于搜索模块时。还提供有关的信息退出模块清理。

要检查版本，您必须使用--version或-V：

python --version

当您使用单个连字符作为前缀时，Python会尝试将版本的每个字符解释为单独的命令行选项。

通常，单词作为命令行选项以两个连字符为前缀，单个字符只有一个或没有。您可以在命令行选项here上阅读有关POSIX指南的更多信息。

在Windows Vista上安装Python 3.4.4后检查版本会产生意外结果
