Ich versuche, eine Python-Bibliothek mithilfe pip
eines SSL-Fehlers zu installieren :
~/projects/base pre-master± pip install xdict
Collecting xdict
Could not fetch URL https://pypi.python.org/simple/xdict/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590) - skipping
Could not find a version that satisfies the requirement xdict (from versions: )
No matching distribution found for xdict
Pip-Version: Pip 9.0.1
Wie behebe ich diesen Fehler?
