在代码中安装python模块

我需要在脚本中直接从PyPi安装一个包。也许有一些模块或distutils(分发，pip等)功能，允许我只执行类似pypi.install('requests')的东西，请求将被安装到我的virtualenv中。

    import pip

try:
    import imaplib
    import email
    import pandas as pd
    # for hiding password
    from pathlib import Path
    from dotenv import load_dotenv
    import os
    import requests
    # 
    from collections import defaultdict
    from itertools import permutations,combinations
except Exception as e:
    print(e)
    e = str(e).split(' ')[-1].replace("'","")
    pip.main(['install', e])

其他回答

你还可以使用如下语句:

import pip

def install(package):
    if hasattr(pip, 'main'):
        pip.main(['install', package])
    else:
        pip._internal.main(['install', package])

# Example
if __name__ == '__main__':
    install('argh')

这应该可以工作:

import subprocess

def install(name):
    subprocess.call(['pip', 'install', name])

    import pip

try:
    import imaplib
    import email
    import pandas as pd
    # for hiding password
    from pathlib import Path
    from dotenv import load_dotenv
    import os
    import requests
    # 
    from collections import defaultdict
    from itertools import permutations,combinations
except Exception as e:
    print(e)
    e = str(e).split(' ')[-1].replace("'","")
    pip.main(['install', e])

import os
os.system('pip install requests')

我尝试了上述临时解决方案，而不是更改docker文件。希望这些可能对一些人有用

我在@Aaron的回答中添加了一些异常处理。

import subprocess
import sys

try:
    import pandas as pd
except ImportError:
    subprocess.check_call([sys.executable, "-m", "pip", "install", 'pandas'])
finally:
    import pandas as pd
