我需要不同版本的 elasticseach-dsl 安装在同一个virtualenv中。我希望能够使用某种别名导入它们：
import elasticsearch_dsl1
import elasticsearch_dsl2
import elasticsearch_dsl5我在考虑创建一个名为 elasricsearch_dsl* 在他们的 setup.py 添加正确版本的安装要求 elasticsearch_dsl 但是当我安装软件包时，会导致冲突，因为我的所有软件包都需要同一个库的不同版本。我不知道如何进行，如果这是可能的。
谢谢大家

我找到了解决问题的办法。
我下载了
elasticsearch-dsl不同版本的库然后将import语句更改为
elasticsearch1,elasticsearch2等库而不是elasticsearchv1.x和v2.x修改了
setup.py更改依赖项的步骤elasticsearch至elasticsearch1,elasticsearch2对于每个版本的elasticsearch-dsl我一直很幸运，因为有elasticsearch1,elasticsearch2... 否则我就得对他们重复同样的程序。更幸运的是，不同版本的库之间的依赖关系是兼容的。我不为这项技术感到骄傲，但它成功了。
设置.py
一个例子
setup.py文件elasticsearch-dls==7.3.0，那么elasticsearch-dsl7```from os.path import join, dirname
from setuptools import setup, find_packages
VERSION = (7, 3, 0)
version = VERSION
versionstr = ".".join(map(str, VERSION))
f = open(join(dirname(file), "README"))
long_description = f.read().strip()
f.close()
install_requires = [
"six",
"python-dateutil",
"elasticsearch7", # before "elasticsearch>=7.0.0,<8.0.0" <---
# ipaddress is included in stdlib since python 3.3
'ipaddress; python_version<"3.3"',
]
tests_require = [
"mock",
"pytest>=3.0.0",
"pytest-cov",
"pytest-mock<3.0.0",
"pytz",
"coverage<5.0.0",
