如何在似乎沒有gcc訪問權限的virtualenv中安裝psycopg2？

Question

我想在virtualenv中安裝psycopg2，但似乎我沒有訪問gcc的權限。

有沒有辦法從virtualenv內部激活gcc？如果沒有，是否還有其他與PostgreSQL協同工作的庫不使用gcc？

我試圖在A2hosting.com安裝psycopg2給了我這個錯誤：

UPDATE：

我發現，關於這一點我正在嘗試安裝psycopg2機器不有PostgreSQL。這個虛擬主機公司在另一臺服務器上安裝了PostgreSQL。在這種情況下可以做些什麼？

Answer 1

你不需要PostgreSQL，你需要PostgreSQL客戶端庫和開發文件。您可以嘗試讓主機安裝它們，否則您可以在類似的平臺上構建它並手動複製軟件包。
