Python3.x Python ModuleNotFound错误，即使安装了模块

为Python3 - python3 -m venv .venv添加虚拟环境.

进入此虚拟环境- source .venv/bin/activate.

添加模块numpy - python3 -m pip install numpy.

然后try 添加模块lap - python3 -m pip install lap. 此命令会产生错误-ModuleNotFoundError: No module named 'numpy'和-ImportError: lap requires numpy, please "pip install numpy"以下的几行.

什么？？

UPDATE

另一个虚拟环境的使用:

vbulash@vbulash-notebook:~/VSCode/recognition$ python3 -m venv .venv2
vbulash@vbulash-notebook:~/VSCode/recognition$ source .venv2/bin/activate
(.venv2) vbulash@vbulash-notebook:~/VSCode/recognition$ python3 -m pip install lap
