Hello,
This is not how pip works: once you have installed a package, you need to add the --upgrade
option to force pip to reinstall a new version. You can also specify the exact version you wish to install:
# this install reservoirpy v0.2.4
pip install reservoirpy
# this update the package to v0.3.0b2
pip install reservoirpy==0.3.0b2
# this should do the same
pip install --upgrade --pre reservoirpy
from reservoirpy.
--update does not seem to be a correct argument for pip:
pip install --update --pre reservoirpy
Usage:
pip install [options] <requirement specifier> [package-index-options] ...
pip install [options] -r <requirements file> [package-index-options] ...
pip install [options] [-e] <vcs project url> ...
pip install [options] [-e] <local project path> ...
pip install [options] <archive url/path> ...
no such option: --update
from reservoirpy.
The command
pip install --pre reservoirpy
install the correct version in my case:
pip install --pre reservoirpy
...
Installing collected packages: reservoirpy
Successfully installed reservoirpy-0.3.0b2
Why is the behaviour different?
PS: in both cases it was under Mac OS
from reservoirpy.
@neuronalX Yes thank you, the option is called --upgrade
. I will edit my comment.
@neuronalX if you run the command with --pre
the first time, then pip will install the pre-release. The problem comes from the fact that @cbrissaud ran the command twice, without forcing the upgrade in between. pip only reinstalls a package if a different version is explicitely specifyed, if it is not in cache or if the --upgrade
option is used.
