Installatie (okt. 2018 - Python 2.7)
- Download .tar.gz-bestand naar
- Pak het bestand uit en plaats inhoud in een map onder /usr/local/bin/ In mijn geval is dat map /usr/local/bin/SQLAlchemy-1.2.12
python setup.py install
- Alleen C-gedeelte lukt niet- Test: Ga naar een andere map (m'n projetmap in dit geval):
python Python 2.7.12 (default, Dec 4 2017, 14:50:18) [GCC 5.4.0 20160609] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import sqlalchemy >>> sqlalchemy.__version__ '1.2.12'
Uninstall (jan. 2019 - Python 2.7)
Dit gaf een permissie-foutmelding:
pip uninstall sqlalchemy /home/strompf/.local/lib/python2.7/site-packages/pip/_vendor/requests/__init__.py:83: RequestsDependencyWarning: Old version of cryptography ([1, 2, 3]) may cause slowdown. warnings.warn(warning, RequestsDependencyWarning) Uninstalling SQLAlchemy-1.2.12: Would remove: /usr/local/lib/python2.7/dist-packages/SQLAlchemy-1.2.12-py2.7-linux-x86_64.egg Exception: Traceback (most recent call last): File "/home/strompf/.local/lib/python2.7/site-packages/pip/_internal/cli/base_command.py", line 143, in main status = self.run(options, args) File "/home/strompf/.local/lib/python2.7/site-packages/pip/_internal/commands/uninstall.py", line 75, in run auto_confirm=options.yes, verbose=self.verbosity > 0, File "/home/strompf/.local/lib/python2.7/site-packages/pip/_internal/req/req_install.py", line 683, in uninstall uninstalled_pathset.remove(auto_confirm, verbose) File "/home/strompf/.local/lib/python2.7/site-packages/pip/_internal/req/req_uninstall.py", line 224, in remove renames(path, new_path) File "/home/strompf/.local/lib/python2.7/site-packages/pip/_internal/utils/misc.py", line 280, in renames shutil.move(old, new) File "/usr/lib/python2.7/shutil.py", line 303, in move os.unlink(src) OSError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/SQLAlchemy-1.2.12-py2.7-linux-x86_64.egg'
Dit werkte wel:
cd /home/strompf/.local/bin sudo pip uninstall sqlalchemy /home/strompf/.local/lib/python2.7/site-packages/pip/_vendor/requests/__init__.py:83: RequestsDependencyWarning: Old version of cryptography ([1, 2, 3]) may cause slowdown. warnings.warn(warning, RequestsDependencyWarning) The directory '/home/strompf/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled.

Installatie SQLAlchemy (jan. 2019 - Python 3.x)
Dit lijkt niet te werken, want het installeert voor Python 2.7. Verder vraagt PIP niet eerst om toestemming, maar installeert gelijk.
