Flask PyCharm Syntax error

Question

I've just started developing a new application using Flask and PyCharm as my IDE. I've encountered a problem which is driving me crazy.

Here is the code. I'll spare use all the import part and so on, I'll show only the routes that cause problems.

@app.route("/")
def home():
    return render_template("home.html")

@app.route("/login/") 
def login():
    return "foo"

The first route works without a problem. However on the first line of the second route, PyCharm gives me an error message '"@" or "def" expected'. This breaks the autoindent and the auto completion features.

But the code runs without a problem.

Can anyone tell me how to fix this?

Thank you

This is because PyCharm is not able to recognize the flask package or version.

Once you add new project to PyCharm -

1. Go to File menu item
2. Click on Settings option
3. This will open-up the pop-up window.
4. In the left-hand-side link list - click on the project name
5. Click on the Project Interpreter link
6. In the right-hand-side pane select Flask and related packages that your project needs and add/install the same.
