pywin32 requirement is not satisfied after installing pypiwin32 - python

Trying to install pyad package for Python 2.7.13 (windows x64) using pip.
There is pywin32 package among requirements, so we get an error:
C:\Windows\system32>pip install pyad
Collecting pyad
Using cached pyad-0.5.16.tar.gz
Requirement already satisfied: setuptools in c:\python27\lib\site-packages (from pyad)
Collecting pywin32 (from pyad)
Could not find a version that satisfies the requirement pywin32 (from pyad) (from versions: )
No matching distribution found for pywin32 (from pyad)
Then I install pypiwin32 which used to work in such cases:
C:\Windows\system32>pip install pypiwin32
Collecting pypiwin32
Using cached pypiwin32-219-cp27-none-win32.whl
Installing collected packages: pypiwin32
Successfully installed pypiwin32-219
But after this I still can't install pyad with the same error as above, like pypiwin32 has never been installed:
C:\Windows\system32>pip install pyad
Collecting pyad
Using cached pyad-0.5.16.tar.gz
Requirement already satisfied: setuptools in c:\python27\lib\site-packages (from pyad)
Collecting pywin32 (from pyad)
Could not find a version that satisfies the requirement pywin32 (from pyad) (from versions: )
No matching distribution found for pywin32 (from pyad)
Folder C:\Python27\Lib\site-packages\pywin32_system32 exists, the pypiwin32 package seems to be installed.
Any ideas to fix this?


You are facing pywin32 installation problem, which is a binary wheel.
You can download binary wheels of pywin32 here. You install it with
pip install pywin32-221-cp27-cp27m-win32.whl
if it is the file you have downloaded
Select the correct version with respect to your installation (Python version and 32/64 bit Python version)
You can have detailed instructions here


pyad is declaring it needs "the pywin32 distribution package" in order to be installed. Distribution packages, i.e. something from PyPI that you can pip install, differ from Python packages, folders with an __init__.py that can be imported. The naming is confusing.
So, because it's not installed, it tries to install pywin32, but it can't find a distribution that matches your Python environment: Python 2.7 on Windows x64. On PyPI it appears like the only distributions are for Python 3.6: https://pypi.python.org/pypi/pypiwin32/220

No module named 'OpenSSL' in python

I search on google how to add OpenSSL in python. The command is easy to run.
pip install pyOpenSSL or pip3 install pyOpenSSL. I don't know if my OpenSSL is already installed. I have this response when I installed openssl.

this is my index.py code
import base64
import json
import requests
from OpenSSL import crypto
when I run this command python3 index.py. I always get this error
ModuleNotFoundError: No module named 'OpenSSL'
May i know what's the issue in my setup? Im new in python code. My python version is 3.10.0

It looks like you have pyopenssl installed for a Python 3.9 installation (look at the path: /usr/local/lib/python3.9), but you are trying to run with a Python 3.10 installation.
Use the pip from your Python 3.10 installation to install the required packages. python3 -m pip install pyOpenSSL should do that, regardless of what the standalone pip command resolves to.

Multiple packages cannot install on PyCharm

I am trying to use PyCharm for my python 3 coding on my Linux, and it works great 90% of the time, but I notice that on occasion I cannot import certain packages. For example, when I click Settings->Project->Python Interpreter and try to install 'opencv-python', I get this error:
AttributeError: module 'setuptools.build_meta' has no attribute '__legacy__'
When I try to install opencv-python with pip I get this message:
$ pip install opencv-python
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: opencv-python in ./.local/lib/python3.6/site-packages (4.5.1.48)
Requirement already satisfied: numpy>=1.13.3 in ./.local/lib/python3.6/site-packages (from opencv-python) (1.19.2)
There seems to be some discrepency between the packages my computer has installed and the packages that PyCharm has installed. How can I solve this problem?

Error installing scrapy in python 3.5 [duplicate]

This question already has answers here:
python spyder conda install failure
(2 answers)
Why does "pip install" inside Python raise a SyntaxError?
(7 answers)
Closed 5 years ago.
I am installing Scrapy in Python 3.5. I am referring to the installation guide here .
I have installed pip and conda. I tried both ways mentioned in the guide, but am getting this error:
I have already installed pip and minoconda:
conda install -c scrapinghub scrapy
and
pip install Scrapy
What is wrong with the installation?

You're trying to install scrapy in the python interpreter, you should install the package in your terminal. What's more, one requirement of installing scrapy is python 2.7, you're using python 3.5
Update:
Good news: Python 3 is Coming to Scrapy, you can try pip install scrapy==1.1.0rc1 now. Note that there are still some limitations, but won't be long that scrapy will have full of 3.x support. Pay close attention to the scrapy development ;)

Scrapy doesn't work with Python 3. At the moment, scrapy works only with Python 2.7.

You can pip install scrapy on python 3.5+, you just have to pip install all the deppendencies first - from here https://docs.scrapy.org/en/latest/intro/install.html
pip install lxml
pip install parsel
pip install w3lib
pip install twisted
pip install cryptography
pip install cryptography
pip install pyOpenSSL
and finally
pip install scrapy - worked for me

Before installing Scrapy on Python 3.5 on Windows 10 in virtualenv
Install lxml,PyDispatcher then simpy install Scrapy code is attached.

I was able to install scrapy on Python 3.5.
Check to see if you are able to install these Twisted, lxml and pyOpenSSL.
In my case I got error in installing lxml. I fixed it by downloading lxml‑3.6.4‑cp35‑cp35m‑win_amd64.whl from http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml based on your Python and windows version. (Credit to Christoph Gohlke's generosity for sharing this library.). Installed it using the following command:
pip install lxml‑3.6.4‑cp35‑cp35m‑win_amd64.whl

pip install livewires gets no matching distribution found for pygame

I am getting the following errors when run pip install livewires:
Collecting livewires
Using cached LiveWires-2.1.tar.gz
Collecting pygame (from livewires)
Could not find a version that satisfies the requirement pygame (from livewires) (from versions: )
No matching distribution found for pygame (from livewires)
I am in Mac with python 2.7.10, and this package can not be installed through my editor (Pycharm) neither.

Using cached LiveWires-2.1.tar.gz
Maybe there is a problem with the cached version. Try using the --no-cache-dir flag to force a fresh download.
pip install --no-cache-dir livewires
