Because this distribution was installed --multi-version, before you can
|
import modules from this package in an application, you will need to
|
'import pkg_resources' and then use a 'require()' call similar to one of
|
these examples, in order to select the desired version:
|
|
pkg_resources.require("%(name)s") # latest installed version
|
pkg_resources.require("%(name)s==%(version)s") # this exact version
|
pkg_resources.require("%(name)s>=%(version)s") # this version or higher
|
zõ
|
Note also that the installation directory must be on sys.path at runtime for
|
this to work. (e.g. by being the application's script directory, by being on
|
PYTHONPATH, or by being added to sys.path by your code.)

|
bad install directory or PYTHONPATH
|
|
You are attempting to install a package to a directory that is not
|
on PYTHONPATH and which Python does not read ".pth" files from. The
|
installation directory you specified (via --install-dir, --prefix, or
|
the distutils default setting) was:
|
|
%s
|
|
and your PYTHONPATH environment variable currently contains:
|
|
%r
|
|
Here are some of your options for correcting the problem:
|
|
* You can choose a different installation directory, i.e., one that is
|
on PYTHONPATH or supports .pth files
|
|
* You can add the installation directory to the PYTHONPATH environment
|
variable. (It must then also be on PYTHONPATH whenever you run
|
Python and want to use the package(s) you are installing.)
|
|
* You can set up the installation directory to support ".pth" files by
|
using one of the approaches described here:
|
|
https://setuptools.readthedocs.io/en/latest/easy_install.html#custom-installation-locations
|
|
|
Please make the appropriate changes for your system and try again.

|
Fix any globally cached `dist_path` related data
|
|
`dist_path` should be a path of a newly installed egg distribution (zipped
|
or unzipped).
|
|
sys.path_importer_cache contains finder objects that have been cached when
|
importing data from the original distribution. Any such finders need to be
|
cleared since the replacement distribution might be packaged differently,
|
e.g. a zipped egg distribution might get replaced with an unzipped egg
|
folder or vice versa. Having the old finders cached may then cause Python
|
to attempt loading modules from the replacement distribution using an
|
incorrect loader.
|
|
zipimport.zipimporter objects are Python loaders charged with importing
|
data packaged inside zip archives. If stale loaders referencing the
|
original distribution, are left behind, they can fail to load modules from
|
the replacement distribution. E.g. if an old zipimport.zipimporter instance
|
is used to load data from a new zipped egg archive, it may cause the
|
operation to attempt to locate the requested data in the wrong location -
|
one indicated by the original distribution's zip archive directory
|
information. Such an operation may then fail outright, e.g. report having
|
read a 'bad local file header', or even worse, it may fail silently &
|
return invalid data.
|
|
zipimport._zip_directory_cache contains cached zip archive directory
|
information for all existing zipimport.zipimporter instances and all such
|
instances connected to the same archive share the same cached directory
|
information.
|
|
If asked, and the underlying Python implementation allows it, we can fix
|
all existing zipimport.zipimporter instances instead of having to track
|
them down and remove them one by one, by updating their shared cached zip
|
archive directory information. This, of course, assumes that the
|
replacement distribution is packaged as a zipped egg.
|
|
If not asked to fix existing zipimport.zipimporter instances, we still do
|
our best to clear any remaining zipimport.zipimporter related cached data
|
that might somehow later get used when attempting to load data from the new
|
distribution and thus cause such load operations to fail. Note that when
|
tracking down such remaining stale data, we can not catch every conceivable
|
usage from here, and we clear only those that we know of and have found to
|
cause problems if left alive. Any remaining caches should be updated by
|
whomever is in charge of maintaining them, i.e. they should be ready to
|
handle us replacing their zip archives with new distributions at runtime.

Given updater is a callable taking a cache entry key and the original entry
|
(after already removing the entry from the cache), and expected to update
|
the entry and possibly return a new one to be inserted in its place.
|
Returning None indicates that the entry should not be replaced with a new
|
one. If no updater is given, the cache entries are simply removed without
|
any additional processing, the same as if the updater simply returned None.
