使用pip安装email_validator
使用pip安装email_validator
提问于 2020-07-03 02:13:16
我已经安装了email_validator，但是我收到一条错误消息，说它没有安装。它必须安装在我的项目文件夹中吗？或者它可以在主站点包文件夹中？当我运行我的程序时，我收到以下错误消息：
Exception: Install 'email_validator' for email validation support我可以看到我已经将它安装在主站点包python3文件夹中，但是当我运行时
pip install email_validator在我的项目文件夹site-packages文件夹中，终端打印如下：
site-packages % pip install email_validator
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: email_validator in /Users/STL34/Library/Python/3.7/lib/python/site-packages (1.1.1)
Requirement already satisfied: idna>=2.0.0 in /Users/STL34/Library/Python/3.7/lib/python/site-packages (from email_validator) (2.10)
Requirement already satisfied: dnspython>=1.15.0 in /Users/STL34/Library/Python/3.7/lib/python/site-packages (from email_validator) (1.16.0)也不会安装在我的项目文件夹中。
以下是代码：
from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField, SubmitField, BooleanField
from wtforms.validators import DataRequired, Length, Email, EqualTo
class RegistrationForm(FlaskForm):
username = StringField('Username',
validators=[DataRequired(), Length(min=2, max=20)])
email = StringField('Email',
validators=[DataRequired(), Email()])
password = PasswordField('Password', validators=[DataRequired()])
confirm_password = PasswordField('Confirm Password',
validators=[DataRequired(), EqualTo('password')])
submit = SubmitField('Sign Up')
class LoginForm(FlaskForm):
email = StringField('Email',
validators=[DataRequired(), Email()])
password = PasswordField('Password', validators=[DataRequired()])
remember = BooleanField('Remember Me')
submit = SubmitField('Login')回答 4

我解决了这个问题。我使用带有-t标志的pip在我的项目文件夹站点包文件夹中安装email_validator。如果没有-t标志，pip就会在Python3 site-packages文件夹中安装email_validator，这是行不通的。

管理包的最简单方法是虚拟环境，这样项目和站点包之间就没有冲突了。
email_validator示例
sudo apt-get install -y python3-venv python3-pip
mkdir email
cd email
deactivate 2> /dev/null
pip3 show virtualenv
if [ $? -ne 0 ] ; then
pip3 install --upgrade pip
pip3 install --upgrade setuptools
pip3 install virtualenv
fi
# now lets build venv
python3 -m venv venv
source venv/bin/activate
pip3 install email_validator
echo "import email_validator" > email.py
echo "print(email_validator.validate_email('hello@gmail.com'))" >> email.py
python3 email.py输出

你说它不会出现在我的项目里是什么意思。你能把输出发出去吗
from email_validator import validate_email, EmailNotValidError在python文件中
如果您正在使用pyenv，那么也可以从pyenv安装该模块。
