New people for help: self-built module package installation problems-CodePudding

I built contains two functions, called "vsearch. Py" file, would you like to do the following two things:
1. Use setuptools package to create the XML file into a package
2. Use PIP install to install the package
My way is:
1. In the same folder with the other two description file "setup. Py" and "the readme.txt,"
Setup. Py the file content is as follows:

 setup (
Name='vsearch', 
Version='1.0', 
Description="The Head First Python Search Tools', 
The author='HF Python 2 e, 
Author_email='[email protected]', 
Url='headfirstlabs.com', 
Py_modules=[' vsearch], 
)

2. Using CMD to run the setup. Py, code for:

 python setup. Py sdist

,
3. The program has built a dist folder, there are vsearch - 1.0. Tar,
4. Using CMD to perform in the dist folder

 PIP install vsearch - 1.0. Tar

,
But the problem appeared, said system cannot find the file, but clearly this file is here, also please teach a great god,
