Flask语法错误：非ASCII字符'\\ xe2'

Question

I'm new to Flask and I'm trying to go through introductory tutorials( here ). I simply copy and paste the code and do the steps

SyntaxError: Non-ASCII character '\xe2' in file main.py on line 8, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

Indeed, I opened the link in the error and googled the error and checked few search items but I didn't get the clue.

It looks lie there is a problem with the syntax of this line

app.config[‘SQLALCHEMY_DATABASE_URI’] = ‘sqlite:///’ + os.path.join(basedir, ‘app.sqlite’)

My whole purpose is getting intoduced on how to use Flask and to CURD operation using SQLite database.

Answer 1

You're using the unicode character "right single quotation mark" (') as per http://www.fileformat.info/info/unicode/char/2019/index.htm

If you change this to use a normal single quote, it should work.

app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///' + os.path.join(basedir, 'app.sqlite')
