PyCharm error: RuntimeError, Click will abort further execution because Python 3

Question

I am learning Flask and first to use PyCharm.

Here is the template code:

from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_world():
    return 'Hello World!'
if __name__ == '__main__':
    app.run()

When i click to run, Here is the Error Info:

This system lists a couple of UTF-8 supporting locales that
you can pick from.  The following suitable locales where
discovered: af_ZA.UTF-8, am_ET.UTF-8, be_BY.UTF-8, bg_BG.UTF-8, ca_ES.UTF-8, cs_CZ.UTF-8, da_DK.UTF-8, de_AT.UTF-8, de_CH.UTF-8, de_DE.UTF-8, el_GR.UTF-8, en_AU.UTF-8, en_CA.UTF-8, en_GB.UTF-8, en_IE.UTF-8, en_NZ.UTF-8, en_US.UTF-8, es_ES.UTF-8, et_EE.UTF-8, eu_ES.UTF-8, fi_FI.UTF-8, fr_BE.UTF-8, fr_CA.UTF-8, fr_CH.UTF-8, fr_FR.UTF-8, he_IL.UTF-8, hr_HR.UTF-8, hu_HU.UTF-8, hy_AM.UTF-8, is_IS.UTF-8, it_CH.UTF-8, it_IT.UTF-8, ja_JP.UTF-8, kk_KZ.UTF-8, ko_KR.UTF-8, lt_LT.UTF-8, nl_BE.UTF-8, nl_NL.UTF-8, no_NO.UTF-8, pl_PL.UTF-8, pt_BR.UTF-8, pt_PT.UTF-8, ro_RO.UTF-8, ru_RU.UTF-8, sk_SK.UTF-8, sl_SI.UTF-8, sr_YU.UTF-8, sv_SE.UTF-8, tr_TR.UTF-8, uk_UA.UTF-8, zh_CN.UTF-8, zh_HK.UTF-8, zh_TW.UTF-8

I think the line is important.

RuntimeError: Click will abort further execution because Python 3 was configured to use ASCII as encoding for the environment.

I find the answer Click will abort further execution because Python 3 was configured to use ASCII as encoding for the environment .

While still not to know how to fix it.

Instructions is very needed, which is easy to follow .

Have you tried putting `# coding: utf8` at the beginning of your file (first line)? — Thibault D., Jul 05 '18 at 12:13
FYI for those wondering "why python3 can error out because of something small like unset locale (i.e. env vars `LANG`, `LC_ALL`)" --> read [PEP 538](https://www.python.org/dev/peps/pep-0538/) and the related [PEP 540](https://www.python.org/dev/peps/pep-0540/). The error appears to only be an issue for python 3.0 to 3.6 because PEP 538 fixes the issues for python >= 3.7. — Trevor Boyd Smith, Oct 18 '21 at 14:41

@Trevor Boyd Smith，it has been 3 years. I am not a python programmer any more — dengApro, Oct 19 '21 at 01:21
