Hallo liebe Phytoneers

ich hoffe, Ihr habt das neue Jahr gut begonnen.

Wenn ich auf ubuntu 22.04 versuche mit pip  install gevent==21.8.0

bekomme ich einen Fehler:

raise Exception("Version mismatch: this is the 'cffi' package version %s, 
located in %r.  When we import the top-level '_cffi_backend' extension module, 
we get version %s, located in %r.  The two versions should be equal; check your 
installation." % (
       Exception: Version mismatch: this is the 'cffi' package version 1.15.1, 
located in 
'/tmp/pip-build-env-_ntr8swv/overlay/local/lib/python3.10/dist-packages/cffi/api.py'. 
When we import the top-level '_cffi_backend' extension module, we get version 
1.15.0, located in 
'/usr/lib/python3/dist-packages/_cffi_backend.cpython-310-x86_64-linux-gnu.so'. 
The two versions should be equal; check your installation.

die einzige Möglichkeit, diesen Fehler zu unterdrücken, die ich gefunden habe, 
ist Python3 vollständig mit

apt purge python

vollständig zu deinstallieren, und wieder zu installieren.
pip uninstall cffi
genügt nicht.


Gibt es einen weniger radikalen weg, diesen Fehler zu beseitigen?

Ich möchte keine virtuelle Umgebung Nutzen, da ich einen system-service einrichte.

danke für Eure Hilfe.

Robert
