/usr/local/bin/python3: No module named pip
Error on or near line 85; exiting with status 1

我已经尝试了很多事情，那么我该如何解决呢？

Answer 1

这意味着您需要使用此命令安装 pip -

sudo apt install python3-pip

如果 python3 是安装的唯一版本的 python，则pip在使用时应调用 pip3。

Answer 2

因为您已经python3-pip安装了软件包，所以您需要将其调用为pip3：

pip3 list
sudo pip3 install virtualenv

Answer 3

创建一个符号链接，在/usr/local/bin/python3/pip其中引用 file /usr/local/bin/pip2.7。

sudo ln -s /usr/local/bin/pip2.7 /usr/local/bin/python3/pip  

然后将目录更改为~/intel/computer_vision_sdk_2018.3.343/deployment_tools/model_optimizer/install_prerequisites并运行sudo ./install_prerequisites.sh
