Ubuntu Linux 上的 Django：“找不到满足要求的版本”

尝试在 Linux Ubuntu 上安装 django（通过虚拟机）。Python3、pip3 已成功安装（因为我可以在我的计算机上成功验证每个版本的版本）。

   > sudo apt-get install python3 python3-pip
Reading package lists... Done
Building dependency tree       
Reading state information... Done
python3 is already the newest version (3.6.7-1~18.04).
python3-pip is already the newest version (9.0.1-2.3~ubuntu1.18.04.1).
0 upgraded, 0 newly installed, 0 to remove and 332 not upgraded.

当我尝试安装 django 时，显示此错误消息。

    > pip3 install Django

  Could not find a version that satisfies the requirement Django (from versions: )
No matching distribution found for Django

对 Linux 故障排除有点陌生；欢迎提供反馈！

答案1

如果你看一下错误消息的最后一行No matching distribution found for Django- 它说pip3找不到名为的发行版Django。这是因为发行版名称区分大小写。

你想要的是pip3 install django。

模块django全部小写。
