Pip Error : 'module' object has no attribute 'Cryptography_HAS_SSL_ST'

Question

I tried to install from pip and keep on getting similar type of errors.

$ pip install quandl
Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    load_entry_point('pip==1.5.6', 'console_scripts', 'pip')()

    if _lib.Cryptography_HAS_SSL_ST:
AttributeError: 'module' object has no attribute 'Cryptography_HAS_SSL_ST'

Now even though i tried to install different pip modules iam getting same error.Is there any solution for this ? This was caused due to the unexpected killing of the process while a pip module is being downloaded.

Please help me with the necessary steps to rectify this error.

I tried to install this

$ pip install -U cryptography

  File "/usr/bin/pip", line 9, in <module>
    load_entry_point('pip==1.5.6', 'console_scripts', 'pip')()

It seems that something related to SSL is missing. You probably should upgrade your pip (never know) : pip install --upgrade pip and then try to pip OpenSSL with : pip install pyOpenSSL — iFlo

@FlorianJOUFFREAU even to upgrade pip it is showing same error. — SaiKiran

uninstall pip and reinstall it. sudo apt-get purge python-pip — Vikash Singh

Ubuntu 16.04.3 here:

I think I have fixed this by removing the python-openssl package (and it's dependencies) with:

apt-get --auto-remove remove python-openssl

Then installing the latest version with pip:

pip install pyOpenSSL

Of course, if you install another apt package that depends on it, it'll pull it back in. I hope if you use pip for everything you can from now on instead of apt, it should be fine.

Edit: as of January 2019 this issue doesn't seem to exist any more.

Thanks, but I needed to do pip install pyopenssl.

M-Jack Over a year ago

Also on Ubuntu 16.04.3 : apt-get --auto-remove --yes remove python-openssl removes a lot of dependencies packages ! including landscape-common, python-qt4 and oneconf. I had to reinstall them after issuing this command : apt install landscape-common python-qt4 oneconf and then finally pip install pyopenssl

Asfand Qazi Over a year ago

@M-Jack Perhaps it's better to not use --auto-remove then?

M-Jack Over a year ago

Not sure... I have tried only your solution. But it is probably important to reinstall then the packages that have been removed.

Brendan Dolan-Gavitt Over a year ago

It is probably not a good idea to tell people to run a command that removes a package which many other packages depend on, especially with flags that auto-confirm! This ended up removing over 700 packages from my system...

I was able to resolve this by deleting the openssl python lib and reinstalling (purge before install did not work):

$ sudo rm -rf /usr/local/lib/python2.7/dist-packages/OpenSSL/
$ sudo apt install --reinstall python-openssl

Didn't work for me, unfortunately. Brings back the same error after reinstalling. I'm on Ubuntu 16.04.3

Schlueter Over a year ago

@AsfandQazi you should confirm that's the python you're using and the potential location for other methods of installation for the lib. python -c 'import sys; print(sys.path)' will let you know where to look.

If even pip is not working then try following:

sudo easy_install -U cffi
sudo easy_install -U cryptography

It works for me.

To fix it on RHEL/CentOS:

sudo rm -rf /usr/lib/python2.7/site-packages/OpenSSL/
sudo yum install pyOpenSSL

This did it for me on CentOS 7. Cheers!

I got this error and solved it by doing these steps (don't forget to put your own username):

rm -rf /home/<Your Username>/.local/lib/python2.7/site-packages/OpenSSL
sudo rm -rf usr/local/lib/python2.7/dist-packages/OpenSSL/
pip install pyOpenSSL

Try to do the following:

$ rm -rf /home/ubuntu/.local/lib/python2.7/site-packages/OpenSSL
$ rm -rf /home/ubuntu/.local/lib/python2.7/site-packages/pyOpenSSL-0.15.1.egg-info

In the last line, you might have another version of pyOpenSSL, specify yours.

I needed to delete it from both directories /usr/lib and /usr/local/lib then reinstalling cryptography==2.6.1 and pyopenssl==19.0.0 on ubuntu 20.04. I installed it using pip3.

Quick Fix

Move the OpenSSL folder to OpenSSLBAK (for instance) to avoid the error

# cd /usr/lib/python2.7/dist-packages
# mv OpenSSL OpenSSLBAK

It should be good

Try to download the suitable wheel file from here depending in your operating system and python version. Then add this file to Python/Scripts and use the code below to install it.

pip install nameofwheelfile.whl

The wheel file contains all the dependencies.

Problem is not only for a specific module,i can do this method.But real problem is it is not working for any module.Even i enter pip it produces the same results.

zinon Over a year ago

OK. If you try as a sudo user do you get the same error as well?

SaiKiran Over a year ago

YES same result

zinon Over a year ago

Hm.. Did you try to upgrade pip?

Schlueter Over a year ago

That link is for windows python libs, the question is tagged with linux and ubuntu so that won't help much.
