將django項目複製到另一臺PC（postgreSQL）

Question

我在筆記本中有一個項目，我想將它複製到我的桌面。我使用Windows 7中的

我安裝了python 3.5（不同版本，說實話，在我的筆記本上是3.4）和postgreSQL。 當然的目錄結構是不同的。在我的筆記本是：

C：/ Python34 /腳本/ myproject1

C：/ Python34 /腳本/ myproject1/myvenv

雖然在我的桌面：

d：/ Python的/ PROGETTI/myproject1

d：/ Python的/ PROGETTI/myproject1/myvenv

所以我在D:/Python/progetti/複製C:/.../myproject1，刪除myvenv主任Y，創造了一個新的virtualenv（同名），並試圖安裝從requirements.txt的要求，但它給出了一個錯誤：

它看起來有一些問題PostgreSQL的，我想。請注意，數據庫尚不存在。

謝謝您的幫助

Answer 1

的Python 3.5目前不蟒蛇的Postgres驅動psycopg2支持：

The current psycopg2 implementation supports:

• Python 2 versions from 2.5 to 2.7
• Python 3 versions from 3.1 to 3.4
• PostgreSQL versions from 7.4 to 9.4

一個簡單的解決辦法是建立一個Python 3.4 virtual environment並運行項目那裏。

Answer 2

我認爲Python 3.5需要MS Visual C++ 2015（看起來here），所以我安裝了它。我不確定這是不是一件好事，因爲它安裝了類似於17（！）的更多MS .NET Framework 16（！）MS SQL Server,4或5個以上MS Visual C++,Ms web deploy和其他2-3個事項在我的控制面板中=>程序和功能。這大概是2GB的東西，安裝/下載需要花費2個多小時......這是正常的嗎？

然後我注意到，在我的requirements.txt有psycopg2==2.6.1而psycopg2 2.6.2（實際版本）支持Python 3.5和PostgreSQL 9.5，所以我升級而不是降級其他...

它的工作原理，但也許我可以卸載MS visual 2015嗎？
