How to downgrade some packages?

easior lars

Terrible thing happened!
~x86 is a ghost.

Today Ibus and Ibus-pinyin are upgraded after syncing.
But the processing of compiling Ibus-pinyin is stopped by some bug.
Now The Ibus dosen't work. I couldn't type Chinese character in gentoo absolutely.

So, How to downgrade ibus to the previous version?

Thank you!

按照Portage的Sandbox机制，编译过程中的错误不会对目前安装的软件包造成任何影响。

既然决心使用~x86，就应该做好相应的准备。按照中国的老话说，没有金刚钻，就不要揽瓷器活。如无绝对把握，建议换回x86。

我今天同样编译了ibus-1.3.99.20110419-r1和ibus-pinyin-1.3.99.20110217（~amd64）。没有任何问题。

如果确实需要downgrade，可以执行：

2. emerge =ibus-1.3.9-r2 =ibus-pinyin-1.3.11

复制代码

估计错误出在设置上，可以考虑：

2. rm -r ~/.ibus ~/.config/ibus

复制代码

此外环境变量最好检查一下。

我估计楼主使用的overlay里面有gentoo-china

portage tree 里的 ibus-pinyin 没有问题

既然决心使用~x86，就应该做好相应的准备。按照中国的老话说，没有金刚钻，就不要揽瓷器活。如无绝对把握，建议换回x86。

我今天同样编译了ibus-1.3.99.20110419-r1和ibus-pinyin-1.3.99.20110217（~amd64）。没有任何问题。

如果确实需要downgrade，可以执行：

1. 
   
2. emerge =ibus-1.3.9-r2 =ibus-pinyin-1.3.11
   

复制代码

估计错误出在设置上，可以考虑：

1. 
   
2. rm -r ~/.ibus ~/.config/ibus

You are right. I'm too simply, sometime naive!

how to downgrade the whole gentoo system?

easior lars

我胡漢三又回來啦！哈哈哈。。。

學了一招

emerge =ibus-1.3.9-r2 =ibus-pinyin-1.3.11

話說回來，本來覺得Gentoo很激進，
不過看看隔壁Fedora 15，
Gnome 3， GCC 4.6等等都用上了，
也就不覺得什麼了。

gentoo 不激进啊…… arch 的版本号激进，fc 技术上激进……gentoo 很保守啊，openrc 今年才默认，systemd 还在 overlay 里呆着……

修改ACCEPT_KEYWORDS之后emerge -avuDNl world即可。

是否激进，主要取决于使用者而非发行版。发行版所影响的，至多不过是尝试新版本的方便程度。激进的人使用Debian同样可以激进，保守的人用Gentoo，几个月更新也未尝不可。

嗯，fcitx表示毫无升级压力。
