Conan: Command Not Found

shell-script python path command

Solution 1

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.

Solution 2

On ubuntu 18.04, after installation of the software performing pip3 install --user conan or pip install --user conan

Doesn't properly link the binary into your path. You could set the path usually because --user installs it into ~/.local/ (on a per user basis) because installing with sudo globally breaks things.

One quick option is to merely create the symlink by performing sudo ln -s ~/.local/bin/conan /usr/bin/conan

it's a small work around, however you could also add ~/.local/bin as such: export PATH=$PATH:/home/<user>/.local/bin

and you will also be able to execute any installed binaries from here as well.

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 ..
popd
```
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:
/home/pi/Wolk...conanbuildinfo.cmake
```
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:
```
/home/pi/.local/lib/python2.7/site-packages
```
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" 
```
ABSOLUTE PATH TO CONAN REPOSITORY FOLDER
```
sys.path.append(conan_repo_path)
from conans.client.command import main
main(sys.argv[1:])    
```
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.

  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 - Thanks for the help but the output of the bash script still say conan:command not found.
