今天滚系统，再次遭遇包冲突：

是youcompleteme 依赖了的新包 python2-requests 导致的。

==> New package :
extra/python2-chardet 2.3.- (required by python2-requests)
extra/python2-requests 2.11.- (required by vim-youcompleteme-git)
extra/python2-urllib3 1.19.- (required by python2-requests)
community/python2-bottle 0.12.- (required by vim-youcompleteme-git)
community/python2-future 0.16.- (required by vim-youcompleteme-git)
community/python2-futures 3.0.- (required by vim-youcompleteme-git)
community/python2-jedi 0.9.- (required by vim-youcompleteme-git)
community/python2-waitress 1.0.- (required by vim-youcompleteme-git)

查看了冲突文件，并不属于任何包：

[tong@T7:~]
% pacman -Qo /usr/lib/python2./site-packages/requests/certs.py
error: No package owns /usr/lib/python2./site-packages/requests/certs.py
[tong@T7:~]
% pacman -Qo /usr/lib/python2./site-packages/requests/cookies.py ↵
error: No package owns /usr/lib/python2./site-packages/requests/cookies.py
[tong@T7:~]
% pacman -Ql python2-requests ↵
error: package 'python2-requests' was not found
[tong@T7:~]

查看 pip2，发现是pip2安装的这个包：

[tong@T7:~]
% pip2 list --format=legacy |grep request
requests (2.10.)
[tong@T7:~]
%

从 pip2 卸载掉该包：

[tong@T7:~]
% sudo pip2 uninstall requests ↵
Uninstalling requests-2.10.:
/usr/lib/python2./site-packages/requests-2.10..dist-info/DESCRIPTION.rst
... ...
/usr/lib/python2./site-packages/requests/utils.pyc
Proceed (y/n)? y
Successfully uninstalled requests-2.10.

再滚一次：

( /) Updating the desktop file MIME type cache...
( /) Updating the MIME type database...
(/) Updating Vim help tags...
==> Packages no longer required by any installed package:
boost ncurses5-compat-libs

圆满成功，T7又一次获得了进化。:)

当然还有另一招，就是 --force 。
