导航到包含.whl文件的目录,然后键入:
select t1.ID,
t2.type,
t1.value,
t2.other
from table1 t1 inner join table2 t2
ON t1.ID = t2.ID
inner join (select ID, min(type) mv
from table2
group by id) m
on t2.id = m.id
and t2.type = m.mv
union all
select t1.ID,
t2type,
null,
t2.other
from table1 t1 inner join table2 t2
ON t1.ID = t2.ID
and not exists (
select 1 from (
select ID, min(type) mv
from table2
group by id) m
where t2.id = m.id
and t2.type = m.mv
)
order by id,type
我得到了:
Twisted-17.9.0-cp27-cp27m-win32.whl不支持此轮 平台。
我也试过64位版本有同样的错误信息:
pip install Twisted-17.9.0-cp27-cp27m-win32.whl
我查了一下:
pip install Twisted-17.9.0-cp27-cp27m-win_amd64.whl
要求已经满足:转入
pip install wheel
我的操作系统:c:\users\yang\appdata\local\programs\python\python36\lib\site-packages
答案 0 :(得分:1)
这很明显。我没有意识到这个" cp27"在文件名中表示python版本。 Twisted-17.9.0-cp27-cp27m-win32.whl用于python 2.7,但我有3.6。
