Python Flask Gunicorn配置说“从flask_ckeditor导入CKEditor，CKEditorField ImportError：没有名为flask_ckeditor的模块”

Question

我正在使用python 3.7环境，flask框架以及最新的ckeditor 5，实际上，我可以使用以下命令在localhost中顺利运行它，而不会出现任何错误：python script.py。但是当涉及到gunicorn配置时，gunicorn --bind 0.0.0.0:5000 wsgi：app我遇到了这个错误：“从flask_ckeditor导入CKEditor，CKEditorFieldImportError：没有名为flask_ckeditor的模块”，我真的不知道该怎么办，希望有人能帮助我。

这里是代码：

import os
from flask_sqlalchemy import SQLAlchemy
from sqlalchemy import create_engine, Column, Integer, String, Sequence
from sqlalchemy.ext.declarative import declarative_base
from flask import Flask
import hashlib
from flask_wtf import FlaskForm
from flask_wtf import Form
from wtforms import StringField, PasswordField, BooleanField
from wtforms.validators  import InputRequired, Email, Length
from flask_bootstrap import Bootstrap
from flask_jwt_extended import JWTManager
from flask_ckeditor import CKEditor, CKEditorField
db = SQLAlchemy()
jwt = JWTManager()

ckeditor = CKEditor()
def create_app(config_type): # dev, test, prod

    # create flask instance
    app = Flask(__name__)
    app.config['CKEDITOR_SERVE_LOCAL'] = True
    app.config['CKEDITOR_HEIGHT'] = '800px'
    app.config['CKEDITOR_WIDTH'] = '800px'
    ckeditor.init_app(app)
    #app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql://postgres:postgres@localhost/catalog_db'

    # setup configuration
    configuration = os.path.join(os.getcwd(), 'config', config_type + '.py')

    # load configuration from file
    app.config.from_pyfile(configuration)

    # attach flask to db instance(SQLALCHEMY)
    db.init_app(app)

    #attach flask to jwt
    jwt.init_app(app)
    Bootstrap(app)
    # import blueprints
    # inside app thats why app.catalog

对于其他遇到这种奇怪问题的人。请在安装pip时使用python env，这可能会解决此问题。
