为什么SQLAlchemy不出现在‘Why 3 search SQLAlchemy’的搜索结果中？

Question

我想安装用于Python3的SQLAlchemy，用于处理数据库。

我使用pip3 search SQLAlchemy搜索包，但没有找到SQLAlchemy作为结果的一部分。

当包在SQLAlchemy上可用时，为什么PyPI不出现在下面的输出中呢？

https://pypi.org/project/SQLAlchemy/

pip install SQLAlchemy

pip3 --version**:**

Answer 1

$ pip search sqlalchemy | wc -l
100

对于pip search返回的结果和纯SQLAlchemy不适合的结果，似乎有一个(合理的)限制。

pip search没有增加限制的方法(它是在服务器端施加的)，也没有办法要求一个不同的页面。
