PyCharm错误：RuntimeError，单击将中止进一步执行，因为Python 3

Question

我正在学习Flask，并且首先使用PyCharm。

这是模板代码：

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

当我单击运行时，这是错误信息：

Traceback (most recent call last):

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

我认为这句话很重要。

  

RuntimeError：单击将中止进一步执行，因为Python 3   配置为使用ASCII作为环境的编码。

我找到了答案Click will abort further execution because Python 3 was configured to use ASCII as encoding for the environment。

虽然仍然不知道如何解决它。

非常需要说明，很容易遵循。

可以从此处打开运行/调试配置。

您可以在其中添加环境变量。（单击环境变量旁边的3点图标）
