I'm not sure why, but when I'm installing hashlib, it gives me an error. I've already tried a good number of potential solutions, and I'd appreciate any help.

$ pip install --user hashlib

can't install hashlib manually

$ pip install --user hashlib

Note1 : pip is usually a python2 command.

Note2 : A contemporary "hashlib" is present by default:

$ locate hashlib.py
/snap/core/4486/usr/lib/python3.5/hashlib.py
/snap/core/4571/usr/lib/python3.5/hashlib.py
/snap/pulsemixer/23/usr/lib/python3.5/hashlib.py
/snap/pulsemixer/8/usr/lib/python3.5/hashlib.py
/snap/software-boutique/31/usr/lib/python3.5/hashlib.py
/snap/ubuntu-mate-welcome/169/usr/lib/python3.5/hashlib.py
/usr/lib/python2.7/hashlib.py
/usr/lib/python2.7/hashlib.pyc
/usr/lib/python3.6/hashlib.py

Hashlib-2008 : Like the name says → year 2008: Files that old will often fail with gcc-7.

Manually : Get hashlib-20081119.zip https://files.pythonhosted.org/packages/74/bb/9003d081345e9f0451884146e9ea2cff6e4cc4deac9ffd4a9ee98b318a49/hashlib-20081119.zip

Example with Ubuntu 18.04 and python2 ( Fails with python3 ):

sudo apt install g++ g++-5

unzip hashlib-20081119.zip
cd hashlib-20081119/
export CC=gcc-5 && python setup.py build && sudo python setup.py install
