Question

默认情况下，pip会搜索包名称和描述。对于某些软件包，这会导致大量的虚假命中，并找到我真正想要的那个是痛苦的。

我怎么告诉pip我只想按姓名搜索？

Answer 1

好吧，在Linux / OSX上，用一些grep / egrep来做半手动操作并不困难（OSX往往要求你使用egrep进行正则表达式，Linux不这样做）

下面的搜索会返回很多东西（实际上是41，如果你把它推到wc）。

pip search psycopg

输出的前几行：

gevent-psycopg2 (0.0.3)              - pip-installable package for patching psycopg2 to use gevent
django-psycopg2-pool (0.1.1)         - A db backend for Django using the gevent psycopg2-pool
pg4nosql (0.4.2)                     - A simple psycopg2 based wrapper for nosql like database interaction with python.
zope.psycopgda (1.1.1)               - Psycopg Database Adapter for Zope 3
qmarkpg (0.2)                        - A psycopg2 wrapper using the qmark parameters style

但是如果你查看pip输出，你会看到packaname字段倾向于以版本名称终止 - psycopg（1.1.21）

所以，请写下来：

pip search psycopg | egrep "^.*psycopg.*\("

输出：

gevent-psycopg2 (0.0.3)              - pip-installable package for patching psycopg2 to use gevent
django-psycopg2-pool (0.1.1)         - A db backend for Django using the gevent psycopg2-pool
zope.psycopgda (1.1.1)               - Psycopg Database Adapter for Zope 3
psycopg2-managed-connection (1.0.0)  - Thread-safe connection manager for psycopg2 connections.
db-psycopg2 (0.0.7)                  - psycopg2 driver for db

psycopg2 (2.6.1)                     - psycopg2 - Python-PostgreSQL Database Adapter
psycopg2-dateutils (0.1)             - Use dateutils.relativedelta to represent PostgreSQL interval types
psycopg2ct (2.4.4)                   - An implementation of the psycopg2 module using ctypes.

psycopgda (1.0)                      - Psycopg Database Adapter for Zope 3
psycopg-postgis (0.1.1)              - Pyscopg helpers to work with PostGIS.
psycopg2cffi (2.7.2)                 - .. image:: https://travis-ci.org/chtd/psycopg2cffi.svg?branch=master
psycopg2cffi-compat (1.1)            - A Simple library to enable psycopg2 compatability
little_pger (0.65)                   - A thin layer just a tad above SQL, for use with PostgreSQL and psycopg2, when you want to wrap queries in a convenient way, using plain data structures (but you don't feel like using an ORM, for some reason).
psycopg (1.1.21)                     - Python-PostgreSQL Database Adapter
psycopg2da (2.0.9)                   - Python psycopg2 database adapter for Zope

这假定包名中没有括号。

作为可重复使用的bash函数（放入.profile等）：

pipsearchpackagename(){
    #a bash function.
    pip search $1 | egrep "^.*"$1".*\("
}

Answer 2

目前无法实现，因为当前实施（点8.1.1）执行了name OR summary查询hard-coded in pip search command，但PyPI XML RPC支持不同的查询。

如何仅按名称搜索pip包？
