UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 35: ordinal not in range(128)

I'm trying to install pyopenssl v 0.13.1 on my kali linux distro.

when I do:

sudo pip install pyopenssl==0.13.1

Downloading/unpacking pyopenssl==0.13.1
  Downloading pyOpenSSL-0.13.1.tar.gz (254kB): 254kB downloaded
  Running setup.py (path:/tmp/pip_build_root/pyopenssl/setup.py) egg_info for package pyopenssl

....

it returns this error:

What can i try now?

thanks!

Solution

I experienced almost identical errors while trying to install the leveldb package, and the numpy package--this doesn't just seem to be a problem with pyOpenSSL.

I was able to fix it by installing the python-devel package on Fedora 20. According to the answer to this question, the python headers are necessary to install packages using the pip tool (at least this seems to be the case for many packages).

Since Kali seems to be a Debian-based distro, the name of the package you'll want is python-dev.

Let me know if this works.
