Cookiecutter：jinja2.exceptions.TemplateSyntaxError：预期令牌'打印语句结束'，得到'：'答案

【问题描述】：

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。

我已经从一个工作的本地项目创建并修改了它，该项目在运行 python manage.py runserver 时成功显示了一个 web 应用程序。

但是，当我尝试运行我的 cookie 项目时，我得到了一个用于第三方 js.min.js.map 文件的 jinja2.exceptions.TemplateSyntaxError: expected token 'end of print statement', got ':'，如下所示：

好像 cookiecutter 正在尝试解析 map 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发生这种情况？

我尝试使用我的千篇一律项目时出现错误

标签： python-3.x cookiecutter

【解决方案1】：

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

如here 所述，可以选择复制而不呈现 jinja2 模板。

所以...我将cookiecutter.json 更新为：

{
  "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！
