 <!-- jQuery -->
    <script src="../bower_components/jquery/dist/jquery.min.js"></script>

    <!-- Bootstrap Core JavaScript -->
    <script src="../bower_components/bootstrap/dist/js/bootstrap.min.js"></script>

    <!-- Metis Menu Plugin JavaScript -->
    <script src="../bower_components/metisMenu/dist/metisMenu.min.js"></script>

    <!-- Custom Theme JavaScript -->
    <script src="../dist/js/sb-admin-2.js"></script>

这称为shebang，告诉你的shell应该根据manage.py中python的哪个版本来使用哪个python安装。

如果第一行不是#!/usr/bin/env python3，那应该是。{如果是，您应该将 python3的位置添加到$PATH。

您需要将以下内容添加到#!/usr/bin/env python3：

中

$PATH

终端只运行2.7，即使在更改别名
