EnvironmentError: [Errno 2] (other issue?)

Open Kouwe-sudo opened this issue 4 years ago • 8 comments

[] I've read the Troubleshooting Wiki, my problem is not described there and I am already using the specified minimum bluez version.

Describe the bug I don't know what causes the bug but I keep getting an error and the solution described with the existing ERRNO 2 doesn't work for me because those condition is already met..

To Reproduce Steps to reproduce the behavior:

  1. Go to '~/bt-mqtt-gateway $...'
  2. Run: source .venv/bin/activate
  3. Run: sudo ./gateway.py -d
  4. See error

Expected behavior I expected to run the program and get messages from my 2 Xiaomi MyFlora

Config Used config

Debug gateway logs

run gateway.py with -d switch and paste formatted output log

try to run:

pip install `./gateway.py -r configured`

zewelor avatar Dec 19 '20 16:12 zewelor

Unfortunately that didn't work for me with this error:

 pi@raspberrypi:~/bt-mqtt-gateway $ pip install `./gateway.py -r configured`
Traceback (most recent call last):
  File "./gateway.py", line 11, in <module>

    import yaml
ModuleNotFoundError: No module named 'yaml'
ERROR: You must give at least one requirement to install (see "pip help install")

By the way: I did upgrade pip after a warning to:

WARNING: You are using pip version 20.3.1; however, version 20.3.3 is available.
You should consider upgrading via the '/home/pi/bt-mqtt-gateway/.venv/bin/python -m pip install --upgrade pip' command.

Kouwe-sudo avatar Dec 19 '20 18:12 Kouwe-sudo

Did you run sudo pip3 install -r requirements.txt before ?

zewelor avatar Dec 19 '20 18:12 zewelor

Yes I did. No errors when a ran that during set-up.

Kouwe-sudo avatar Dec 19 '20 18:12 Kouwe-sudo

Try "sudo pip install ./gateway.py -r configured"

zewelor avatar Dec 20 '20 08:12 zewelor

That didn't help either with the next Error:

 $ sudo pip install ./gateway.py -r configured
Invalid requirement: './gateway.py'
It looks like a path. File './gateway.py' does not exist.

Kouwe-sudo avatar Dec 20 '20 15:12 Kouwe-sudo

I think I solved it. Bluepy was in the wrong folder namely Python2.7. I renamed that Folder and reinstalled Bluepy by using: sudo pip3 install bluepy.

Now I get results from MQTT

The only now is that I get an error when running:

sudo systemctl status bt-mqtt-gateway

With an ERROR like this:

Perhaps you have a clue, but I'm convinced I will solve that problem as well. For now it runs, but I have to restart it after a reboot myself. I can live with that for the moment.

Kouwe-sudo avatar Dec 21 '20 14:12 Kouwe-sudo

I know this is a kind of hacky way (because you leave dependencies in a two places)

But it worked for me adding this line to service.sh:

python3 -m pip install -r requirements.txt

then start the service, check if it works and remove the line afterwards
