I'm using a server for the first time. It has Ubuntu 18.04.
I've never worked with that OS, but after some guides I managed to get my code working, except for the environment variable.
In ~/.bashrc at the end of file I added export KEY="123asd".
Then I reloaded the terminal.
I checked if my environment variable is loaded via printenv KEY and it shows the correct value.
In my main.py there's:
import os
import telebot
API_KEY = os.getenv("KEY")
bot = telebot.TeleBot(API_KEY)
When I run it with pm2 start main.py --interpreter=python3 there's an error in logs:
raise Exception('Bot token is not defined')
Exception: Bot token is not defined
If I understand correctly it means that API_KEY is None so there's a problem with the environment variable.
I tried giving API_KEY an actual value, not an environment variable, and it worked fine.
So what else do I need to do to use an environment variable properly?
I was looking in the wrong place.
If I want to use pm2 then I need to create a ecosystem.config.js file and give it my variable. Like this:
module.exports = {
apps : [{
name: "main.py",
env: {
KEY: "123asd"
}
}]
}
It works, only I'm not sure if it's correct since there are more than 1 processes of my main.py (1 online, others are erorred)

Hey guys I am trying to deploy my project on the rinkeby chain using infura, but I am getting a ValueError
Here is my trackback:

I have a really little experience in coding. I think the problem is related to .env, but I don't know what I should now. FYI I am using windows n follow this course

stuck at 4:48:00
it appears your env variables are not set correctly, and it looks like in this case it's your WEB3_INFURA_PROJECT_ID.
You can fix it by setting the variable in your .env file and adding dotenv: .env to your brownie-config.yaml.
brownie-config.yaml:
dotenv: .env
.env:
export WEB3_INFURA_PROJECT_ID=YOUR_PROJECT_ID_HERE
Remember to save these files.
Additionally, you should be on at least brownie version v1.14.6. You can find out what version you're on with:
brownie --version
I had the same issue (Mac OS) and I looked at another YouTube around Brownie Deployment and noticed that "network" needs to be defined at import.
This line of code above the from brownie import did the trick in my deploy.py:
import brownie.network as network
I've had this error for days and have seen it posted alot online.
I was simply 1 directory up from where I needed to be - I followed the Patrick Collins tutorial very closey with the addition of setting up a virtual env, so maybe others are simply having the same problem I had.
I was originally in a directory "\demos\web3 brownie" which contained a folder called "brownie" and my python virtual env files.
The script is now running when I'm in directory "\demos\web3 brownie\brownie" which contains the brownie build, script, contract directories
I followed the same course and was stuck too. I just put my infura project ID as a environment variable on my system(windows10) not on the .env file.

I have a web server with CGI script calling python scripts.
When i try to execute in a main file (test1.py) another script called via
os.system('/var/www/cgi-bin/readIRtemp.py '+arg1+' '+arg2+' '+arg3)
I get his error message in /var/log/apache2/error.log :
import: not found
from: can't read /var/mail/jinja2
this is understandable for me since when called directly from the python console my script works !
its content is:
import sys, os
from jinja2 import Environment, FileSystemLoader, select_autoescape
last20values=sys.argv[1]
currTempInDegreesCelcius=sys.argv[2]
print('test '+last20values+' '+currTempInDegreesCelcius)
env = Environment(
loader=FileSystemLoader('/var/www/html/templates'),
autoescape=select_autoescape(['html', 'xml'])
)
template = env.get_template('IR.html')
updatedTemplate=template.render( arrayOfTemp = last20values, currTemp=currTempInDegreesCelcius)
Html_file=open("/var/www/html/IR.html","w")
Html_file.write(updatedTemplate)
Html_file.close()
I read somewhere something like maybe when calling os.system() the script is running with a different user account or some crazy things like that ... please help!
of course i chmod 777 * everything but that doesnt help ...
I'm new to Python. This is my first Ansible module in order to delete the SimpleDB domain from ChaosMonkey deletion.
When tested in my local venv with my Mac OS X, it keeps saying
Module unable to decode valid JSON on stdin. Unable to figure out
what parameters were passed.
Here is the code:
#!/usr/bin/python
# Delete SimpleDB Domain
from ansible.module_utils.basic import *
import boto3
def delete_sdb_domain():
fields = dict(
sdb_domain_name=dict(required=True, type='str')
)
module = AnsibleModule(argument_spec=fields)
client = boto3.client('sdb')
response = client.delete_domain(DomainName='module.params['sdb_domain_name']')
module.exit_json(changed = False, meta = response)
def main():
delete_sdb_domain()
if __name__ == '__main__':
main()
And I'm trying to pass in parameters from this file: /tmp/args.json.
and run the following command to make the local test:
$ python ./delete_sdb_domain.py /tmp/args.json
please note I'm using venv test environment on my Mac.
If you find any syntax error in my module, please also point it out.
This is not how you should test your modules.
AnsibleModule expects to have specific JSON as stdin data.
So the closest thing you can try is:
python ./delete_sdb_domain.py < /tmp/args.json
But I bet you have your json file in wrong format (no ANSIBLE_MODULE_ARGS, etc.).
To debug your modules you can use test-module script from Ansible hacking pack:
./hacking/test-module -m delete_sdb_domain.py -a "sdb_domain_name=zzz"
I already set SLACK_TOKEN environment Variable. But "SLACK_TOKEN=os.environ.get('SLACK_TOKEN')" is returning "None".
The type of SLACK_TOKEN is NoneType. I think os.environ.get not fetching value of environment variable. so rest of the code is not executing.
import os
from slackclient import SlackClient
SLACK_TOKEN= os.environ.get('SLACK_TOKEN') #returning None
print(SLACK_TOKEN) # None
print(type(SLACK_TOKEN)) # NoneType class
slack_client = SlackClient(SLACK_TOKEN)
print(slack_client.api_call("api.test")) #{'ok': True}
print(slack_client.api_call("auth.test")) #{'ok': False, 'error': 'not_authed'}
def list_channels():
channels_call = slack_client.api_call("channels.list")
if channels_call['ok']:
return channels_call['channels']
return None
def channel_info(channel_id):
channel_info = slack_client.api_call("channels.info", channel=channel_id)
if channel_info:
return channel_info['channel']
return None
if __name__ == '__main__':
channels = list_channels()
if channels:
print("Channels: ")
for c in channels:
print(c['name'] + " (" + c['id'] + ")")
detailed_info = channel_info(c['id'])
if detailed_info:
print(detailed_info['latest']['text'])
else:
print("Unable to authenticate.") #Unable to authenticate
I faced similar issue.I fixed it by removing quotes from the values.
Example:
I created a local.env file wherein I stored my secret key values :
*local.env:*
export SLACK_TOKEN=xxxxxyyyyyyyzzzzzzz
*settings.py:*
SLACK_TOKEN = os.environ.get('SLACK_TOKEN')
In your python terminal or console,run the command : *source local.env*
****Involve local.env in gitignore.Make sure you dont push it to git as you have to safeguard your information.
This is applicable only to the local server.Hope this helps.Happy coding :)
In my case, I write wrong content in env file:
SLACK_TOKEN=xxxxxyyyyyyyzzzzzzz
I forgot export befor it, the correct should be:
export SLACK_TOKEN=xxxxxyyyyyyyzzzzzzz
You can use a config file to get the env vars without using export,
in the env file store varibale normally
.env:
DATABASE_URL=postgresql+asyncpg://postgres:dina#localhost/mysenseai
Then create a config file that will be used to store the env variable like so
config.py:
from pydantic import BaseSettings
class Settings(BaseSettings):
database_url: str
class Config:
env_file = '.env'
settings = Settings()
than you can use it that way
from config import settings
url = settings.database_url
If you declared the variable SLACK_TOKEN in the windows command prompt you will be able to access it in the same instance of that command prompt not anywhere including Powershell and the git bash. Be careful with that
whenever you want to run that python script, consider running it in the same command prompt where you declared those variables
you can always check if the variable exists in the cmd by running echo %SLACK_TOKEN% if it does not exists the cmd will return %SLACK_TOKEN%
I often find myself recreating file structures for Flask apps so I have decided to make a script to do all that for me. I would like the script to create all the folders I need as well as the files with some basic boilerplate, which it does, that part is working fine. However I would also like to create a virtual environment and install Flask to that environment. That is where I am encountering the problem. The script runs but it installs Flask to my system installation of Python.
I followed the advice in this question here but it's not working. I am running Ubuntu 12.04.4 LTS via crouton on a Chromebook.
#!/usr/bin/python
from os import mkdir, chdir, getcwd, system
import sys
APP_NAME = sys.argv[1]
ROOT = getcwd()
PROJECT_ROOT = ROOT + '/' + APP_NAME

folders = {APP_NAME : {'app' : {'static': {'css' : '', 'img' : '', 'js' : ''}, 'templates' : ''} } }
def create_folders(dic):
for key in dic:
if isinstance(dic[key], dict):

I suppose your calls are not within the same console session and therefore the console environment is not as expected. I suggest to concatenate the related commands in one system call using subprocess.Popen like this (including suggestions by limasxgoesto0):
subprocess.Popen('virtualenv venv;source venv/bin/activate;pip install flask')
You should probably be using subprocess; os.system is deprecated.
