Just now I update the latest python and want to install packages through pip, but there raise a error:

I google this error and tried to update Openssl, but it does not work.
My Openssl version is OpenSSL 1.0.2o 27 Mar 2018
My python version is Python 2.7.14
My pip version is pip 9.0.1
My ~/.base_profile is like this:
export PATH=/usr/local/bin:$PATH
PATH=$PATH:/usr/local/mysql/bin
# Setting PATH for Python 2.7
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
export PATH
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
export PATH="/usr/local/opt/openssl/bin:$PATH"
someone said it is because some micro changes by shadowsocks, but it did not explain why and how to deal with it.
So what should I do to repair my pip and ssl?

As I answered here https://stackoverflow.com/a/49798838/9586409.
You have to upgrade pip to a version with a TLSv1.2 support. You can do it by running this command:
curl https://bootstrap.pypa.io/get-pip.py | python

Installing twisted on Windows 10 64 bit under python 2.7

Does anyone know how to do this. I have googled and the best that I could come up with was to do:
pip install autobahn[twisted]
when I do that I get this error in the command window

I have no idea how to fix the error

Go to University of California Irvine's Unofficial Windows Binary for Python Extension Packages and download the Twisted wheel file. This is the easy way. The hard way requires a compiler (comes packaged in Windows Built Tools) to be installed.
PLEASE NOTE!!!! For anyone stumbling onto this thread, only the latest package is available for download (usually) through the University of California Irvine site, so it would be wise to SAVE the binaries for future use. This is very useful if a specific version is required. Otherwise the specific compiler needs to used to compile packages.

Requests can verify SSL certificates for HTTPS requests, just like a
web browser. To check a host’s SSL certificate, you can use the verify
argument:
And if you want to avoid the SSLError you can find the requests part and change verify to False:
requests.get('https://google.com', verify=False)
Another way reinstall certifi module:
sudo pip uninstall -y certifi
sudo pip install certifi==2015.04.28

I've been arround searching for an answer in the internet without success. A lot of answers from 2012 suggest to downgrade, but the bug that was troublesome had been fixed since that.

As additional information, I did an elementaryos fresh install a few weeks ago. This happens to ALL packages. I have installed everything through apt, so this seems Any ideas?

Following the suggestion by #andersson I tried to install pip's latest version. Then this poped out

It seems to be a generic problem.

My problem was slightly different. It looks like the https://pypi.python.org/simple/ certificate was renewed in June 2016, so if the date of your OS is prior to that date, you'll have problems validating the certificate, no matter if the proper CA certs are installed.

I have also some issues with default (1.5.4) pip version. Can you successfully update pip to up-to-date (6.1.1) version or you have already tried and instalation failed with both pip versions?

Promptly solved by:
sudo update-ca-certificates

Pip install from requirements file is failing, but installing one by one works

I am trying to install a bunch of python dependencies using a requirements.txt file with the following command:

The requirements.txt file has the following packages:

But for some reason if I install all packages using pip install <package> they all get installed correctly.
A couple of things to consider;
1) since I am in my company's intranet I am setting a proxy using set https_proxy=https://company-proxy.com:port. 2) Installing the exact same packages using requirements.txt in a Linux machine works fine. Any ideas?
Update:
I was using Python 2.7 for 64 bits. I uninstalled it and installed the 32 bits, and I no longer had this problem. Looks like the python version was the problem, the 64 bits one for some reason cause problems.
