Gentooのpipを使おうとすると最新のPythonを要求され、最新のPythonをemergeしようとしたら、最新のgccをemergeしなければならない。と、なったのが先日の話。
gccをアップデートしたなら、
emerge -uDN @world
をやらねば、なんだったらカーネルもアップデートしないと、"gccのバージョン違うドライバだよ!"って言われたりするので、やりたいなぁ。なんて思います。(思わないか?)
んで、やると、readlineというツールでslot conflictが発生します。
!!! Multiple package instances within a single package slot have been pulled !!! into the dependency graph, resulting in a slot conflict: sys-libs/readline:0 (sys-libs/readline-7.0_p3:0/7::gentoo, ebuild scheduled for merge) pulled in by >=sys-libs/readline-7.0:0= required by (app-shells/bash-4.4_p12:0/0::gentoo, ebuild scheduled for merge) ^^ ^^^^^^ (sys-libs/readline-6.3_p8-r3:0/0::gentoo, installed) pulled in by sys-libs/readline:0/0= required by (sys-apps/util-linux-2.30.2:0/0::gentoo, installed) ^^^^^ >=sys-libs/readline-6.2_p5-r1:0/0=[abi_x86_64(-)] required by (sys-libs/slang-2.3.0:0/0::gentoo, installed) ^^^^^ >=sys-libs/readline-4.1:0/0= required by (net-misc/ntp-4.2.8_p10-r1:0/0::gentoo, installed) ^^^^^ >=sys-libs/readline-4.1:0/0= required by (dev-lang/python-2.7.14-r1:2.7/2.7::gentoo, installed) ^^^^^ sys-libs/readline:0/0= required by (sci-libs/libqalculate-0.9.9:0/6::gentoo, installed) ^^^^^ >=sys-libs/readline-4.1:0/0= required by (dev-lang/python-3.6.3-r1:3.6/3.6m::gentoo, installed) ^^^^^ sys-libs/readline:0/0= required by (dev-libs/libpcre-8.41-r1:3/3::gentoo, installed) ^^^^^ >=sys-libs/readline-6.2_p5-r1:0/0=[abi_x86_64(-)] required by (dev-db/unixODBC-2.3.4-r1:0/0::gentoo, installed) ^^^^^ sys-libs/readline:0/0=[abi_x86_64(-)] required by (dev-db/sqlite-3.20.1-r1:3/3::gentoo, installed) ^^^^^ sys-libs/readline:0/0= required by (net-wireless/bluez-5.47-r1:0/3::gentoo, installed) ^^^^^ lang/python-3.5.4-r1:3.5/3.5m::gentoo, installed) ^^^^^ >=sys-libs/readline-5.2:0/0= required by (sys-block/parted-3.2-r1:0/0::gentoo, installed) ^^^^^ sys-libs/readline:0/0= required by (app-text/hunspell-1.6.1-r1:0/1.6::gentoo, installed) ^^^^^ sys-libs/readline:0/0= required by (dev-lang/ruby-2.2.9:2.2/2.2::gentoo, installed) ^^^^^ sys-libs/readline:0/0= required by (app-crypt/gnupg-2.2.0:0/0::gentoo, installed) ^^^^^ It may be possible to solve this problem by using package.mask to prevent one of those packages from being selected. However, it is also possible that conflicting dependencies exist such that they are impossible to satisfy simultaneously. If such a conflict exists in the dependencies of two different packages, then those packages can not be installed simultaneously. For more information, see MASKED PACKAGES section in the emerge man page or refer to the Gentoo Handbook.
すみません。いくつかのパッケージ端折ってます。
これ、どうにかするには、
/etc/portage/package.use
に、
dev-lang/python sqlite
という1行を追加して、pythonのUSEフラグに"sqlite"を追加し、
emerge dev-lang/python
で、pythonをemergeし直してから、@worldをemergeすると、slot conflict問題は解決するそうです。
