Não consigo instalar o hashlib manualmente

Question

Não sei por que, mas quando estou instalando hashlib , isso me causa um erro. Já experimentei um bom número de possíveis soluções e agradeço qualquer ajuda.

$ pip install --user hashlib

Answer 1

can't install hashlib manually

$ pip install --user hashlib

Nota 1: pip é normalmente um comando python2.

Nota 2: Um "hashlib" contemporâneo está presente por padrão:

$ 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: Como o nome diz → ano 2008: Arquivos antigos geralmente falharão com gcc-7 .

Manualmente: obtenha hashlib-20081119.zip link

Exemplo com o Ubuntu 18.04 e python2 (falha com 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
.
.
