Question

我在同一目录示例中有flaskblog.py和forms.py。但是当我尝试“从表单导入RegistrationForm，LoginForm”代码时，我在PyCharm中编译了时间错误。

我成功地能够这样导入：从sample.forms导入RegistrationForm，LoginForm

此后，当我尝试使用python flaskblog.py运行代码时，出现以下错误：

(venv) C:\Users\ksrihari\PycharmProjects\myFlaskStudy\sample>python flaskblog.py
Traceback (most recent call last):
  File "flaskblog.py", line 2, in <module>
    from sample.forms import RegistrationForm, LoginForm
ModuleNotFoundError: No module named 'sample'


from flask import Flask, render_template, url_for
from sample.forms import RegistrationForm, LoginForm
import datetime
app = Flask(__name__)
app.config['SECRET_KEY'] = 'a515c030528fbddb08443cea4e6fd96c'

posts = [
    {
        'author':'Corey Schafer',
        'title':'Blog Post1',
        'content':'First Blog Post',
        'date_posted':'18, May 2019',
        'last_updated_date':f"{datetime.datetime.now()::%d, %b %Y}"
    },
    {
        'author':'Srihari K S S',
        'title':'Blog Post2',
        'content':'Second Blog Post',
        'date_posted':'18, May 2019',
        'last_updated_date':f"{datetime.datetime.now()::%d, %b %Y}"
    }
]

@app.route("/")
@app.route("/home")
def home():
    return render_template('home.html', posts=posts)

@app.route("/about")
def about():
    return render_template('about.html', title='About')

@app.route("/register")
def register():
    form = RegistrationForm()
    return render_template('register.html', form = form, title = 'Register')

@app.route("/login")
def register():
    form = LoginForm()
    return render_template('login.html', form = form, title = 'Login')

if __name__ == '__main__':
    app.run(debug=True)[enter image description here][1]

如果它是一个程序包（带有 init .py文件的目录），请按以下方式导入它：

from package_name.forms import ClassName

如果它不是软件包，而只是单独的模块，则可以这样导入：

from forms import ClassName

干杯！

无法导入同一目录中存在的文件
