Eu executei o comando sudo easy_install-3.6 pip na minha máquina Linux sem saber as conseqüências e agora pip3 parou de funcionar como esperado. Por exemplo, estou tentando instalar o Rasa Core e o comando pip3 install rasa_core resulta em:
<< Long list of Requirement already satisfied... >>
launchpadlib 1.10.5 requires testresources, which is not installed.
spacy 2.0.10 has requirement html5lib==1.0b8, but you'll have html5lib 0.9999999 which is incompatible.

Ou algo como pip3 install requests resulta em:

Na verdade, as últimas 6 linhas desse erro, algo sobre problemas de incompatibilidade, repita para cada comando pip3 install .
O que devo fazer para voltar aos dias mais simples?
Eu estava pesquisando sobre isso e há muitas informações sobre ambientes virtuais, mas nada disso faz sentido para um inexperiente. Parece haver uma infinidade de pacotes e comandos relacionados ao ambiente virtual, e coloco alguns comandos nele. Não faço ideia de como usar o ambiente, como e como sair. Todas as outras fontes parecem ter um conjunto de comandos ligeiramente diferente. Por favor, guie!
