Ecco lo screenshot:

Penso che l'errore è causato dal pacchetto python. Ho aggiornato python e ho provato di nuovo ma non è stato utile.

Qual è l'errore e come posso risolverlo?

Answer 1

Questo ha funzionato per me.

sudo apt-get install python-pip 

sudo pip install --upgrade pip 

Sembra che io abbia installato e aggiornato python.

Ricordo di averlo provato prima ma non ha funzionato. Non so perché, ma ha funzionato ora.

Sarebbe utile se qualcuno può indicare il motivo dell'errore e delineare la soluzione.

Answer 2

Hai provato questo?

sudo pip install -U os-testr

Answer 3

nella riga di comando:

sudo apt-get install python-pip 
sudo pip install --upgrade pip 
sudo pip install -U os-testr 

questo ha funzionato bene per me ...
