##################pycharm下载依赖包##########################
pip freeze >requirements.txt

pip download -d ./packages -r requirements.txt
当使用 --platform（操作系统）、–python-version（python 版本）、–implementation或–abi（解释器版本），作为限制条件时，必须设置–no-deps（不下载所依赖的模块），或者设置–only-binary=:all:（），并且不能设置–no-binary（或者必须设置为–no-binary=:none: ）

##################服务器安装venv##########################
https://pypi.org/search/?q=virtualenv

$ tar xvfz virtualenv-X.X.tar.gz
$ cd virtualenv-X.X
$ sudo python3 setup.py install

注：此处可能出现缺少依赖的情况，需要根据实际情况补充
下载地址–https://pypi.org/search/?q=&o=，搜索到后下载whl文件。

python3 -m pip install pyparsing-3.0.9-py3-none-any.whl
python3 -m pip install packaging-21.3-py3-none-any.whl
python3 -m pip install typing_extensions-4.4.0-py3-none-any.whl

##################服务器项目启动venv##########################
在项目根路径下启动virtualenv

virtualenv venv // 创建虚拟环境venv，最好在项目根目录下执行
cd venv // 进入虚拟环境目录
source ./bin/activate // 进入虚拟环境

在依赖包所在路径下执行
pip3 install --no-index --find-links=./ <包名> -r <where_you_are>/<项目根目录>/requirements.txt
pip3 list // 查看安装的依赖
实测下列命令会出现安装顺序问题

启动项目
python3 start.py & //根据项目编辑

退出virtualenv
deactivate

#################librdkafka安装##########################
安装依赖：https://github.com/edenhill/librdkafka
