PyCharm's code editor shows the popup message Template file 'index.html' not found when passing "index.html" to render_template. The template templates/index.html exists. Accessing http://localhost:5000/ renders the template. How do I tell PyCharm that the template exists?
@app.route('/')
def index():
return render_template('index.html')

Make sure that you have a file called index. html in the directory where you have configured Flask to look for templates (it's usually a directory called 'templates' in your web app directory).
Flask looks for templates in the templates directory, which is called templates , so the name is important. Make sure you're inside the flask_app directory and run the following command to create the templates directory: mkdir templates.
To resolve the issue, simply create a folder name it “Templates”. Then move “index. html” into this newly created folder.
Right click on your templates directory, go to "Mark Directory as", and select "Template Directory".
