Question

我正在关注Paul Barry撰写的 Head First Python 第二版，尝试并学习使用python。我已经创建了一个函数，将其放入模块中，然后为该模块创建了一个分发文件。现在，我想在计算机上安装它，但似乎无法使分发文件在计算机上运行。

我的代码插入Windows 10命令提示符中并导致错误：

C:\Users\coolt\AppData\Local\Programs\Python\Python36-32\mymodules\dist> py -3 -m pip install vlsearch-1.0.tar
Requirement 'vlsearch-1.0.tar' looks like a filename, but the file does not exist

You are using pip version 9.0.3, however version 18.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

我很困惑，因为该文件确实存在于我指定的位置。如何安装？

the file exists in the folder that I expect it to

似乎无法使用PIP安装我自己的模块
