当我试图创建一个新的应用程序时，我也遇到了同样的问题。如果你写python manage.py startapp myapp，那么它会寻找usr/bin/python。但是你需要这个“python”，它位于你的虚拟env路径的/bin目录下。我通过提到virtualenv的python路径来解决这个问题，就像这样:

<env path>/bin/python manage.py startapp myapp

如果你在virtualenv中，你需要激活它才能运行。/manage.py '命令'

source path/to/your/virtualenv/bin/activate

如果您在.bash_profile或.bashrc中配置workon

workon yourvirtualenvname

*请不要编辑你的manage.py文件，也许不是正确的工作方式，可能会给你未来的错误

只是一个错误 这种情况也发生在我身上。我的错误是在创建虚拟env之前创建了Django项目，后来激活了env并试图启动服务器。激活env后安装Django就可以了

完全同意这是一个路径问题，但我有同样的错误。这是由于在设置虚拟环境时错误地为我的Python可执行文件使用了相对路径。我是这样做的:

virtualenv -p ~/python_runtimes/2.7.3/bin/python venv2.7.3 --distribute

相反，我必须给出Python可执行文件的完整路径。

HTH, 哈林

这是一个解释器错误。

如果你正在使用vscode，那么只需要遵循以下步骤:

视图 命令面板 搜索python 选择翻译 选择windows存储和你的问题将得到解决，几秒钟后，错误已经消失。

路径改变导致此问题。

================================== 解决方案 =========================================

第一个转到：虚拟环境

通过运行命令: 源bin /激活

然后安装django，因为你会得到与import django相关的错误:

pip install django

然后运行:

python manage.py runserver

(注意:请将'runserver'更改为您要运行的程序名称)

对于同样的问题，它在我的案例中起了作用。 ================================== 剧情简介 =========================================
