 Schwerwiegender Fehler: ffi.h: Keine solche Datei oder kein solches Verzeichnis auf pip2 install pyOpenSSL

Post by Guest »

Einer der Schritte, die ich immer verwende, um meinen Ansible-Agenten auf Zielknoten zu installieren/zu erstellen, war pip2 install pyOpenSSL. Dies ist eine Voraussetzung für Ihren Ansible-Client, um das Standard-Ansible-Modul zum Erstellen selbstsignierter Zertifikate verwenden zu können, z. B. openssl_certificate

Seit heute funktioniert dies nicht mehr.

Ich kann diese Nachricht wie folgt reproduzieren:

Code: Select all

vagrant init generic/ubuntu1804
vagrant ssh
sudo su -
apt-get update && apt-get -y install python python-pip
pip2 install pyOpenSSL
Der letzte Schritt schlägt mit der folgenden Meldung fehl. Wie installiert man pyOpenSSL derzeit korrekt unter Ubuntu 18.04? Gibt es eine Problemumgehung für dieses Problem?

Oder besser: Gibt es eine Python-Distribution für Ansible? Das schließt alle Abhängigkeiten ein, sodass ich nicht meinen eigenen Ansible-Client kompilieren und erstellen muss?

Code: Select all
