本文介绍了解决在使用Flask框架时遇到的jinja2.exceptions.TemplateNotFound错误的方法。只需将html文件夹改名为templates，因为Flask默认在此目录下搜索模板。

在搭建时出现jinja2.exceptions.TemplateNotFound，但自己明明已经将运行文件与存放html的文件夹放在了同一层为什么还会出现这样的情况呢？

这个时候只需要做一件特别简单的事情，把存放html的文件夹改名为templates,就好了。因为flask默认在templates中搜索。

这种错误都是templates文件夹放错位置，应该将此templates文件夹放置在运行程序的文件夹中，就是说应该包含在内。

右键点击 `app.py` 文件，选择 `Run 'app'`。在 PyCharm 的项目目录下，右键点击项目名，选择 `New` -> `Python File`，命名为 `app.py`。- `@app.route('/user/<username>')`：定义动态路由，`<username>` 是变量。- `app = Flask(__name__)`：创建应用实例，`__name__` 代表当前模块名。- `@app.route('/')`：装饰器，定义根路径 `/` 的处理函数。

一、检查模板文件夹是否正确。 遇到这个问题，首先需要检查你的模板文件夹命名是否规范，Flask默认会在工程下寻找templates文件夹，这个是默认配置，不能写成template或者其他名字。当然，如果你使用的是PyCharm创建的Flask项目，PyCharm默认会帮你创建这个模板文件夹，你只需要把这个模板文件放在这个模板文件夹中即可。在PyCharm中，这个文件夹有着特殊标记。 当然，我也尝试过取消标记为template Folder，但是Flask依然能准确的找到这个模板文件夹。 .

template_folder这个属性，所以默认是templates这个文件夹，由于__init___.py文件的目录与templates没有在统一目录下，所以找不到。,static_folder=“”,static_url_path=“”)，结果发现出现了这个问题，原来，创建的时候，没有。其中template_folder后面的是相对位置，这样就找到这个目录了。我们在定义这个时，改为。
