我正在使用PostgreSQL作为后端设置新的Django项目。我正在使用pip来安装软件包。以下是在新环境中安装的要求。
Django==1.9
argparse==1.2.1
djangorestframework==3.3.3
psycopg2==2.6.1
wsgiref==0.1.2
我不知道我犯了哪些错误。请帮我配置新项目。请给我一步一步的程序来配置新环境。
错误堆栈是
from psycopg2.extras import DateRange, DateTimeTZRange, NumericRange
ImportError: cannot import name DateRange

Sub CopyData()
'set variables for wkb and ws to copy
Dim wbSource As Workbook
Set wbSource = Workbooks("Source.xlsx")
Dim wsCopy As Worksheet
Set wsCopy = wbSource.Worksheets("Sheet1") 'change name as needed
'set variables for wkb and ws to paste
Dim wbDest As Workbook
Set wbDest = Workbooks("Destination.xlsx")
Dim wsDest As Worksheet
Set wsDest = wbDest.Worksheets("Sheet1")
'copy visible cells for specific range
With wsCopy
Dim lRow As Long
lRow = .Range("D" & .Rows.Count).End(xlUp).Row
Dim rCopy As Range
Set rCopy = Union(.Range("D7:D" & lRow), .Range("F7:F" & lRow), _
.Range("G7:G" & lRow), .Range("I7:I" & lRow), .Range("J7:J" & lRow), _
.Range("K7:K" & lRow), .Range("L7:L" & lRow), .Range("M7:M" & lRow), _
.Range("O7:O" & lRow), .Range("AD7:AD" & lRow), .Range("AX7:AX" & lRow), _
.Range("CO7:CO" & lRow), .Range("CQ7:CQ" & lRow), .Range("CR7:CR" & lRow))
End With
'paste
rCopy.SpecialCells(xlCellTypeVisible).Copy wsDest.Range("A2")
End Sub
适合我。你可以my@box:~ mkvirtualenv env
(env)my@box:~ pip install -r requirements.txt
(env)my@box:~ django-admin startproject proj
(env)my@box:~ ./proj/manage.py shell
>>> from psycopg2.extras import DateRange, DateTimeTZRange, NumericRange
>>>
和import psycopg2吗？

我知道这对于聚会来说为时已晚，但是显然使用psycopg2-binary对我有用。
这与Djano 2.2.9和Djongo 1.3.0一起导入psycopg2失败，并出现以下错误：

我将其发布在这里，因为它是搜索此特定错误时显示的少数几个地方之一。
我要做的就是：
$(venv) pip install psycopg2-binary
