I'm trying to create .exe file in pycharm. When I'm installing pyinstaller by 'import pyinstaller' it gets error.

This is not how pyinstaller works. Rather than importing pyinstaller into your program, you need to run pyinstaller pointing at your program.
From the docs:
Install PyInstaller from PyPI:
pip install pyinstaller
Go to your program’s directory and run:
pyinstaller yourprogram.py
you can use auto-py-to-exe
pip install auto-py-to-exe
to run it
$ auto-py-to-exe

Try to run pip install requirements.txt in code dir.

I cannot install any pip package in my pc it returns that error .I am using v2ray and proxyfire.I don't think these software make trouble with pip command because I use it without any error before formatting my PC.
I already installed Python and added into env var : Python 3.10.1
Appreciate Your support .
I also met the same problem, the reason is Clash Proxy or System Proxy trigger the problem.
so, you need to close Clash or switch off the system Proxy.
What if, in order to boost the downloading speed,you can install TAP Device and open the Service Mode in Clash instead of using System Proxy mode.
I download anaconda as the Internet said, and use command 'conda create -n python python=3.6' and it shows "Collecting package metadata (current_repodata.json):failed" and the error report says:

pip install urllib3==1.25.11
I am a newbie with Python, just install newest 3.9.5 in Windows.
I use pip to install requests module and fail with error "check_hostname requires server_hostname"
All solutions I found is to install old urllib3 module like "pip install urllib3==1.25.11".
But again, I fail with error "check_hostname requires server_hostname" as below. What can I do now?
C:\>pip install urllib3==1.25.11

Thanks to simpleApp's hint in comment!
I am in China and run a proxy program actually. I can successfully install module requests after I close my proxy and try again!!
I'm trying to pip install pip install -i https://pypi.anaconda.org/lapu/simple fix-yahoo-finance but every time I do so, a whole bunch of red text comes out and I don't know what I'm doing wrong. I'm using Windows and Anaconda, I've already installed pip prior to this. Any advice?
The error is as follows:
