I see form my project document that I need to install python-pybind11 by using

sudo apt -y install python-pybind11

but I got error like this:

Reading package lists... Done

Building dependency tree
Reading state information... Done

E: Unable to locate package python-pybind11

I'm not sure if python-pybind11 is a valid package, where can I check it?

  • @FeilixXu, Seems to be a permission issue. Run this with “sudo”. – PrakashG Feb 16 '19 at 06:56
  • now another error: `Traceback (most recent call last): File "/usr/bin/pip", line 9, in from pip import main ImportError: cannot import name main `. I'm using ubuntu16, is that related? –  Feb 17 '19 at 13:46

    Peanut gallery comment: Please don't `sudo pip install`! Consider `pip install --user`, but really, just try using a `virtualenv`! – eacousineau Mar 08 '19 at 13:35

In some systems, you may need

sudo apt -y install python3-pybind11

In Ubuntu 18.04

apt-get install python-pybind11

On Mac,

brew install pybind11

In Ubuntu 16.04, you'll need to install yourself. One way is as follows:

# Some prerequisites (but not all of them)
apt-get install cmake
pip3 install pytest

# Clone, build and install 
git clone https://github.com/pybind/pybind11.git 
cd pybind11 
mkdir build 
cd build 
cmake .. 
make install
