Gentoo - Using Masked Packages

当我想要安装esearch的时候，终端输出如下的信息：$ emerge -vp esearch ... !!! All ebuilds that could satisfy "app-portage/esearch" have been masked. !!! One of the following masked packages is required to complete your request: - app-portage/esearch-0.7.1-r7 (masked by: ~amd64 keyword) - app-portage/esearch-0.7.1-r6 (masked by: ~amd64 keyword) - app-portage/esearch-0.7.1 (masked by: package.mask, ~amd64 keyword) /usr/portage/profiles/package.mask: # Paul Varner <fuzzyray@gentoo.org> (31 Dec 2008) # Masked due to being broken with portage 2.1 and 2.2. # Users can use either the unstable versions or switch to app-portage/eix

这里面有两种mask：kerword masked（~amd64 keyword) 和hard masked(package.mask)

 

对于两种mask有对应的处理方式。

kerword masked：

/usr/portage/app-portage/esearch/esearch-0.7.1-r7.ebuild




vi /etc/portage/package.keywords


    =app-portage/esearch-0.7.1-r7 ~amd64

Hard Masks

/usr/portage/profiles/package.mask


vi /etc/portage/package.unmask


   =app-portage/esearch-0.7.1
