IDF 3.3.1 UBUNTU下安装报错的原因？

操作系统为Ubuntu 18.04.4 LTS，64位
按照安装指导成功安装了准备工作，
sudo apt-get install git wget flex bison gperf python python-pip python-setuptools cmake ninja-build ccache libffi-dev libssl-dev
下载了IDFV3.3.1版本。
运行install.sh后出现如下提示信息：
Installing Python environment and packages

请问谁知道该如何处理该问题。看起来像是建立虚拟环境失败，virtualenv 命令不是别 --no-site-packages 这个参数。该如何解决呢？
