我正在尝试学习如何使用 cookiecutter 并创建了我自己的基于 django 的项目，其中包含一些引用 .js、.map 文件的静态 jinja2 模板。

我已经从一个在运行时成功显示 webapp 的工作本地项目创建并调整了它python manage.py runserver。

但是，当我尝试运行我的 cookie 项目时，我会得到一个jinja2.exceptions.TemplateSyntaxError: expected token 'end of print statement', got ':'第三方js.min.js.map文件，如下所示：

就好像 cookiecutter 正在尝试解析地图文件？cookiecutter 不应该将静态文件复制到新项目中吗？我该如何调试为什么会这样？

当我尝试使用我的千篇一律的项目时出现错误

解决了！问题是 cookiecutter 在复制操作期间试图渲染 jinja2 模板。

如此处所述，有一个选项可以复制而不是渲染 jinja2 模板。

所以......我将我的更新cookiecutter.json为：

{
  "description": "desc",
  "email": "me@example.com",
  "full_name": "Your Name",
  "license": "MIT",
  "project_name": "default_project",
  "python_version": "3.8",
   "_copy_without_render": [
        "*.html",
        "*.js",
        "*.map",
        "*.css"
   ]
}

现在它正在工作！
