Hello,
the logic for installing packages in Sage has changed recently. Let me
explain what changed:
The command "sage -i PKGNAME" now only supports new-style packages. The
PKGNAME should be a bare package name (no version numbers or URLs or
whatever).
Packages are now installed *with* dependencies, which means that you can
actually run "sage -i PKGNAME" right after extracting the Sage sources
(or running "make distclean") and it should work. Within Sage, the
dependencies of a package are stored in
build/pkgs/PKGNAME/dependencies. If PKGNAME is already up-to-date, then
"sage -i PKGNAME" will do nothing.
The command "sage -f PKGNAME" will force install a package, even if it
was already installed (the dependencies are installed, but not force
installed).
The functionality of the old "sage -f" command was moved to "sage -p",
there is no replacement for the old "sage -i". So, "sage -p PKGNAME"
supports new-style and old-style packages (without considering
dependencies). For old-style packages, the bare package name or a full
pathname/URL to a .spkg may be given.
Note that old-style packages are deprecated. If you care about an
old-style package, it should be upgraded to a new-style package. Also,
the old-style standard and archived packages on the Sage server are no
longer considered.
Recall that running "make" will now automatically upgrade new-style
optional packages which are installed and that "sage -t" will
automatically doctest new-style optional packages too.
Finally, note that "sage -i" and "sage -f" actually support make
targets, not just packages. So you can run "sage -f doc" as alternative
to "make doc-clean && make doc" or "sage -f sagelib" as alternative to
"sage -ba", but with dependencies.
Jeroen.
