module flask will not launch

project interpreter and local env IMAGEI'm having a real problem with using the module flask , I've tried a lot of the solutions here on the forum but none has worked.

I can see flask is installed pip list - showing flask in the setting the module flask is installed in project interpreter when I type the code I can see the module comes up

However when I launch the code I get an error

No module named 'flask'

I've tried to re-install pycharm I've tried to uninstall and install flask again still the same problem. Any advice ?

The file name vsearch.py

Here is the code:

from flask import Flask, render_template, request, escape

app = Flask(__name__)

def search4words(phrase: str, letters: str) -> set:
    return set(letters).intersection(set(phrase))

def log_request(req: 'flask_request', res: str) -> None:
    with open('vsearch.log', 'a') as log:
        print(req.form, req.remote_addr, req.user_agent, res, file=log, 
        sep='|')

@app.route('/search4', methods=['POST'])
def do_search() -> 'html':
    phrase = request.form['phrase']
    letters = request.form['letters']
    title = 'Here are your results:'
    results = str(search4words(phrase, letters))
    log_request(request, results)
    return render_template('results.html', the_phrase=phrase, 
                           the_letters=letters, the_title=title, 
                           the_results=results,)

@app.route('/')
@app.route('/entry')
def entry_page() -> 'html':
    return render_template('entry.html', the_title='Welcome back 
    AGAIN!!!!!')

@app.route('/viewlog')
def view_the_log() -> 'html':
    contents = []
    with open('vsearch.log') as log:
        for line in log:
            contents.append([])
            for item in line.split('|'):
                 contents[-1].append(escape(item))
    titles = ('Form Data', 'Remote_addr', 'User_agent', 'Results')
    return render_template('viewlog.html',
                           the_title = 'View log',
                           the_row_titles = titles,
                           the_data = contents,)

if __name__ == '__main__' :
    app.run(debug=True)

Your issue was attempting to run vsearch.py through terminal, rather than through PyCharm's interpreter (which was correctly installed). In order to utilize the virtual environment, you should configure it to be used correctly when running your code.

There are multiple ways of activating your virtual environment, so please find that which is applicable to your project. A good source for this would be https://uoa-eresearch.github.io/eresearch-cookbook/recipe/2014/11/26/python-virtual-env/.
