 Posted: Sat Nov 28, 2020 4:48 am Post subject: [solved] portage will not emerge dev-util/itstool |
 |
|
Following an upgrade to python 3.8, I tried to remove 3.7 and it would not: | hermes ~ # emerge -ac dev-lang/python:3.7: | Calculating dependencies... done!
dev-lang/python-3.7.9 pulled in by:
dev-libs/libxml2-2.9.10-r3 requires dev-lang/python:3.7[xml]
dev-util/itstool-2.0.6-r1 requires dev-lang/python:3.7[xml]
>>> No packages selected for removal by depclean
Packages installed: 367
Packages in world: 40
Packages in system: 43
Required packages: 367
Number removed: 0 |
Trying to do a full update incorporating the PYTHON_TARGETS change to 3.8 results in an error indicating that dev-util/itstool seems to want dev-libs/libxml2 to be built targeting the same python version as it (3.7): | hermes ~ # emerge -uND world: | These are the packages that would be merged, in order:
Calculating dependencies... done!
Total: 0 packages, Size of downloads: 0 KiB
WARNING: One or more updates/rebuilds have been skipped due to a dependency conflict:
dev-libs/libxml2:2
(dev-libs/libxml2-2.9.10-r3:2/2::gentoo, ebuild scheduled for merge) USE="-debug -examples -icu -ipv6 -lzma python readline -static-libs -test" ABI_X86="-32 (64) (-x32)" PYTHON_TARGETS="-python3_6 -python3_7 python3_8 -python3_9" conflicts with
dev-libs/libxml2[python,python_targets_python3_7(-)] required by (dev-util/itstool-2.0.6-r1:0/0::gentoo, installed) USE="" ABI_X86="(64)" PYTHON_SINGLE_TARGET="-python3_6 python3_7 -python3_8"
Nothing to merge; quitting. |
However, trying to rebuild itstool manally to effect the USE change does not result in any action: | hermes ~ # emerge -1N dev-util/itstool: | These are the packages that would be merged, in order:
Calculating dependencies... done!
Total: 0 packages, Size of downloads: 0 KiB
Nothing to merge; quitting. |
The same without USE change does "work" (with no USE change): | hermes ~ # emerge -1p dev-util/itstool: | These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ] dev-util/itstool-2.0.6-r1::gentoo PYTHON_SINGLE_TARGET="-python3_6 python3_7 -python3_8" 0 KiB
Total: 1 package (1 reinstall), Size of downloads: 0 KiB |
The same behavior is seen when emerging dev-libs/libxml2 (-N makes emerge do nothing).
Portage bug?
emerge --info dev-util/itstool

You have changed PYTHON_TARGETS to python3_8 but you haven't changed PYTHON_SINGLE_TARGET which remained at python3_7.

Better way is use /etc/portage/package.use
| Code: | */* PYTHON_TARGETS: -python3_7 python3_8
*/* PYTHON_SINGLE_TARGET: -python2_7 -python3_7 python3_8 |
because when profile change, for example, in python3_9 you will not see this change.
