Question

我正在尝试通过CMD（管理员，W10）安装一组软件包。

我使用了创建的文本文件requirements.txt，如下所示。

psycopg2
requests
jsonlib
os-sys
openpyxl
pandas
numpy

我做了一些研究，从中我发现安装psycopg2是解决方案（因此现在要添加它），但是当Installing backend dependencies时我仍然收到错误消息。我正在Admin CMD中使用pip install -r requirements.txt命令。

完整的CMD报告：

任何人都可以提供帮助，以及如何解决？

尝试一下：

BEGIN
     Declare @Value varchar(50)
     SET @Value = NULL
     SELECT * from TestTable where Value = IIF(@Value is NULL,Value,@Value)
    END

通过CMD安装软件包时出错
