我创建了一个虚拟环境来开发我的python脚本。
当我尝试安装和导入rrdtool时出现错误：
安装：
(venv) pip install rrdtool
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

安装库后，我已在系统上成功安装了python rrdtool：
sudo apt-get install rrdtool python-rrdtool librrd-dev
我尝试将lib复制到我的venv文件夹中，但是没有用。如何将这些库安装到我的venv中？
