            Pip install failing due to pyopenssl / OpenSSL error
            Asked 2022-Jan-07 at 17:24

            I'm running Python 3.8.10 on WSL2 (Windows Subsystem for Linux) in a corporate environment and am encountering the below error, which I believe is related to pyopenssl / OpenSSL, when attempting to install anything using pip. It's not clear to me if I made any system-level changes that led to this strange behavior.

            From the comments, we ultimately determined that the pip downloads were being blocked by company policy.

            Troubleshooting steps that helped us arrive at the right solution:

            • A ping was successful, so we next tried ...

            Asked 2021-Dec-26 at 13:45

            Here is the code for the spider. I am trying to scrape these links using a Scrapy spider and get the output as a csv. I tested the CSS selector separately with beautiful soup and scraped the desired links, but cannot get this spider to run. I also tried to account for DEBUG message in the settings, but no luck so far. Please help



            Answered 2021-Dec-26 at 13:45

            Just a guess - you may be facing a dynamic loading webpage that scrapy cannot directly scrape without the help of selenium.

            I've set up a few loggers with the help of adding headers and I don't get anything from the start_requests. Which is why I made the assumption as before.

            On a additional note, I tried this again with splash and it works.

            Answered 2021-Oct-01 at 14:15

            You're using old mysqlclient 1.3.12 with new MySQL 8. Either you need to downgrade MySQL to version 5.6. Or you need to use later mysqlclient.

            The incompatibility was fixed in commit a2ebbd2 on Dec 21, 2017 so you need a later version of mysqlclient.

            mysqlclient 1.3.13 was released on Jun 27, 2018. Try it or any later version.



            UnsatisfiableError while installing Miniconda
            Asked 2021-Sep-30 at 04:52

            I wanted to reinstall Miniconda. I have first removed the entire Miniconda install directory, edited the bashrc file to remove the Miniconda directory from the PATH environment, and removed the hidden condarc file and conda folder from the home directory.

            Then, I downloaded Miniconda from, and tried to install it with bash

            Doing this, I got the following UnsatisfiableError:

            Miniconda System Requirements Not Met

            Most of the conflicts are superfluous. The key ones are right at the end: all those packages require glibc >= 2.17 and your system (i.e., OS) only has GLIBC 2.12. So, we're talking CentOS 6 or similar RHEL, and this is a known issue that makes the newer Miniconda builds uninstallable for you. If you're deadset on Miniconda, you'll have to hit up the archive for an old version, as suggested on the install page (which, BTW, notes CentOS 7+). Unfortunately, I don't know which Miniconda version was the last to support GLIBC 2.12.

            Alternative: Try Mambaforge

            Fortunately, most of Conda Forge continues to build on COS6 images, so try out a Miniforge variant instead of Miniconda. I highly recommend Mambaforge.

            And yes, testing on the centos6 Docker image, the latest Mambaforge installs and runs just fine.

            Inside Virtual environment:

            pip version = 19.2.3

            Outside Virtual environment:

            pip version = 21.2.4

            python version = 3.8.3

            I tried to upgrade pip inside virtual environment using python -m pip install -U pip and pip install --upgrade pip but it is hanged without producing any output here is the screenshot.

            Python Cryptographic Authority pyopenssl version Before 17.5.0 contains a CWE - 401 : Failure to Release Memory Before Removing Last Reference vulnerability in PKCS #12 Store that can result in Denial of service if memory runs low or is exhausted. This attack appear to be exploitable via Depends upon calling application, however it could be as simple as initiating a TLS connection. Anything that would cause the calling application to reload certificates from a PKCS #12 store.. This vulnerability appears to have been fixed in 17.5.0.
            Python Cryptographic Authority pyopenssl version prior to version 17.5.0 contains a CWE-416: Use After Free vulnerability in X509 object handling that can result in Use after free can lead to possible denial of service or remote code execution.. This attack appear to be exploitable via Depends on the calling application and if it retains a reference to the memory.. This vulnerability appears to have been fixed in 17.5.0.
            The X509Extension in pyOpenSSL before 0.13.1 does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.

            Install pyopenssl

            You can install using 'pip install pyopenssl' or download it from GitHub, PyPI.
            You can use pyopenssl like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
