表现：

使用命令在～路径下安装：

pip3 install evo --upgrade --no-binary evo

安装EVO，发现错误：

ERROR: pandas 0.24.2 has requirement python-dateutil>=2.5.0, but you'll have python-dateutil 2.4.2 which is incompatible.

Installing collected packages: numpy, cycler, kiwisolver, matplotlib, scipy, pytz, pandas, seaborn, natsort, colorama, evo

ERROR: Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/usr/local/lib/python3.5/dist-packages/numpy' Consider using the `--user` option or check the permissions.

解决：

1. 首先尝试：

pip3 install --upgrade python-dateutil

出现错误：

ERROR: Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: 'easter.py'

Consider using the `--user` option or check the permissions.

搜索解决这一问题的方法，发现此链接：[Errno 13] Permission denied How i solve this problem · Issue #236 · googlesamples/assistant-sdk-python · GitHub

按照链接中的解决办法安装虚拟环境：

sudo apt-get install python3-venv

python3 -m venv env

source ./env/bin/activate

重新执行：

pip3 install --upgrade python-dateutil

安装成功。

2. 在此基础上安装：

pip3 install evo --upgrade --no-binary evoCollecting evo

出现error和提示：

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-v3u8zy4g/matplotlib/

You are using pip version 8.1.1, however version 19.2.3 is available.

You should consider upgrading via the 'pip install --upgrade pip' command.

运行：

pip install --upgrade pip

再运行：

pip3 install evo --upgrade --no-binary evo

安装成功。

3.后续使用，打开一个新的terminal后，需要在～路径下先执行

source ./env/bin/activate

再使用evo命令。

4. 使用--plot参数发现错误：
