I believe they are the short form of --alldeps and --onlyreqdeps

我相信它们是--alldeps和--onlyreqdeps的缩写形式

The PEAR installer has full support for dependencies; it can automatically install required and/or optional dependencies if you wish so.

PEAR安装程序完全支持依赖项;如果您愿意,它可以自动安装必需和/或可选的依赖项。

Here's the PEAR Install command manual

这是PEAR Install命令手册

EDIT:

What each does is in the manual, but here's the blurb.

每个人都做了什么在手册中,但这里是模糊。

You have several choices:

你有几个选择:

Install dependent packages by hand

手动安装依赖包

Let PEAR automatically install necessary dependencies only

让PEAR仅自动安装必要的依赖项

Let PEAR automatically install necessary and optional dependencies

让PEAR自动安装必要和可选的依赖项

The first method can be a painful and daunting process, because dependent packages itself can have dependencies.

第一种方法可能是一个痛苦而艰巨的过程,因为依赖包本身可能具有依赖性。

Both other methods just require a switch to the install command, either --onlyreqdeps (install required dependencies only) or --alldeps (install all dependencies).

其他两种方法只需要切换到install命令,可以是--onlyreqdeps(仅安装所需的依赖项)或--alldeps(安装所有依赖项)。
