Hi,
I need your help: I installed mailman3 on a debian stretch environment and faced following problems.
On "mailman start" I got the error message: Starting Mailman's master runner /usr/bin/python3: can't open file '/sbin/master': [Errno 2] No such file or directory
connection to maria-db In debian stretch maria-db is running. In my mailman.cfg I set: [database] class: mailman.database.mysql.MySQLDatabase url: mysql+pmysql://#username#:#user-pawo#@localhost/#databasename#?charset=utf8&use_unicode=1
This produces as errormessage: sqlalchemy.exc.NoSuchModuleError: Can't load plugin: sqlalchemy.dialects:mysql.pmysql
On mailman start the error message is: File "/usr/local/bin/mailman", line 11, in <module> sys.exit(main()) File "/usr/local/lib/python3.5/dist-packages/mailman/bin/mailman.py", line 94, in main initialize(config_path) File "/usr/local/lib/python3.5/dist-packages/mailman/core/initialize.py", line 189, in initialize initialize_2(propagate_logs=propagate_logs) File "/usr/local/lib/python3.5/dist-packages/mailman/core/initialize.py", line 160, in initialize_2 config.db = getUtility(IDatabaseFactory, utility_name).create() File "/usr/local/lib/python3.5/dist-packages/mailman/database/factory.py", line 54, in create database.initialize() File "/usr/local/lib/python3.5/dist-packages/mailman/database/base.py", line 106, in initialize self.engine = create_engine(url, isolation_level='READ UNCOMMITTED') File "/usr/local/lib/python3.5/dist-packages/sqlalchemy/engine/__init__.py", line 424, in create_engine return strategy.create(*args, **kwargs) File "/usr/local/lib/python3.5/dist-packages/sqlalchemy/engine/strategies.py", line 57, in create entrypoint = u._get_entrypoint() File "/usr/local/lib/python3.5/dist-packages/sqlalchemy/engine/url.py", line 156, in _get_entrypoint cls = registry.load(name) File "/usr/local/lib/python3.5/dist-packages/sqlalchemy/util/langhelpers.py", line 221, in load (self.group, name)) sqlalchemy.exc.NoSuchModuleError: Can't load plugin: sqlalchemy.dialects:mysql.pmysql
Can You help??
