我是编程新手，这是我的第一个项目

尝试在服务器上启动Django项目

激活的虚拟环境

在pip install -r requirements.txt命令之后，发生错误

Answer 1

您正在使用什么操作系统？确保正确安装了所有内容，使文件夹遵循官方文档或教程，并确保始终使用正确的环境，在该环境中已通过pip正确安装了Django（我使用pip3），请确保之前具有最新版本支持的Python版本（我使用3.8.2）和最新版本的pip。重新遍历所有段落，看看会发生什么。如果出现问题，请详细说明您的操作。

Answer 2

好了，通过观察您的问题，我发现requirements.txt文件的beautifulsoup4库中有一个拼写错误，并且在提到的注释中，您在安装Django时也遇到了错误

Could not find a version that satisfies the requirement Django==2.0.7 (from -r requirements.txt (line 3)) (from versions: (any versions) .No matching distribution found for Django==2.0.7 –

Django 2以上版本仅支持python3，因此请尝试

pip3 install django==2.0.7

如果您的系统中装有python3.5及更高版本

也可以通过点子查看受支持的版本：

pip install django==0

和

pip3 install django==0

确保您没有使用vpn。

Answer 3

再次解决您的问题，我发现2.0.7确实是正确的版本。但是在您的requirements.txt中，其文字为Django==2.0.7应该是django==2.0.7

在Django项目上未安装requirements.txt
