I'm using a RPI 3B

uname -a returns: 4.14.98-v7+ #1200 armv71

OS is stretch

gcc version is 4.9.3

I'm attempting to setup my RPi to be a BLE gateway as per this project on hackster.io. I executed the first few commands:

git clone --recurse-submodules https://github.com/Wolkabout/WolkGateway.git

sudo apt-get install mosquitto cmake python python-pip && python -m pip install conan

The Bash Script

then I ran a bash script (configure.sh) that contains the following:

!/usr/bin/env bash

cp tools/git/pre-commit .git/hooks/pre-commit
chmod +x .git/hooks/pre-commit

pushd out
conan install -s compiler.libcxx=libstdc++11 --build=missing ..
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release ..

The Output of the Bash Script

the terminal outputs:

line 21: conan: command not found

line 21 is the line with conan.

Then I get a CMake error:

CMakeLists.txt:(20) (include):
include could not find load file:

Maybe Conan Isn't in My PATH

My thought was that the command conan isn't in my $PATH so I checked PIP:

pip show conan

this gave me the location of conan:


I then added that path to my $PATH:

export PATH=$PATH:/home/pi/.local/lib/python2.7/site-packages

This didn't work, causing the same error when re-running the aforementioned bash script (configure.sh)

Installing Conan From Source

I went here and installed conan from source:

 git clone https://github.com/conan-io/conan.git
 cd conan
 pip install -r conans/requirements.txt

The Python Script to Add Conan to my PATH

#!/usr/bin/env python

import sys

conan_repo_path = "/home/pi/conan" 


from conans.client.command import main

This worked. It showed me the conan commands help output.

What is this python script doing differently then when I execute configure.sh (bash script)?

    @Rui F Ribeiro did you down vote my question, if so, please provide the reason so I know for next time. – Niko_Jako Apr 5 at 16:44
  • You're referring to two different paths in your shell script and your Python script. If you do export PATH=$PATH:/home/pi/conan, does the shell script work then? – Haxiel Apr 5 at 17:15
  • @Haxiel - Thanks for the help but the output of the bash script still say conan:command not found. – Niko_Jako Apr 5 at 18:06

When installing conan:

sudo apt-get install mosquitto cmake python python-pip && python -m pip install conan

the later half:

python -m pip install conan

should be installed using sudo:

sudo python -m pip install conan

If this doesn't work, try uninstalling conan:

pip uninstall conan

and then reinstall:

sudo pip install conan

Currently my RPi is running the configure.sh script successfully.
