問題：
This may sound like a stupid question, since the very purpose of virtualenv is to this exactly: Installing some specific version of a package (in this case Django) inside the virtual environment.這聽起來像是一個愚蠢的問題，因爲virtualenv的真正目的就是：在虛擬環境中安裝某個特定版本的包（在本例中爲 Django）。 But it's exactly what I want to do, and I can't figure it out.但這正是我想要做的，我想不通。
I'm on Windows XP, and I created the virtual environment successfully, and I'm able to run it, but how am I supposed to install the Django version I want into it?我在 Windows XP 上，並且成功創建了虛擬環境，並且能夠運行它，但是我應該如何將我想要的 Django 版本安裝到其中？ I mean, I know to use the newly-created easy_install script, but how do I make it install Django 1.0.7?我的意思是，我知道要使用新創建的easy_install腳本，但是如何讓它安裝 Django 1.0.7？ If I do easy_install django , it will install the latest version.如果我執行easy_install django ，它將安裝最新版本。 I tried putting the version number 1.0.7 into this command in various ways, but nothing worked.我嘗試以各種方式將版本號1.0.7放入此命令中，但沒有任何效果。
How do I do this?我該怎麼做呢？
