I have a main.py file and a connection_voice.ogg file in the same directory and at first I thought the problem was connecting the audio file. But now I understand that the problem is not in the audio file.
music = SoundLoader.load('connection_voice.ogg')
if music:
music.play()
And I don't understand what an 'unzip' file or directory is. Please give some advice
So, to solve this you need to enter to terminal sudo apt-get install unzip. And than this problem will be solved.
The file structure should look like :
test.py
node_modules (The folder containing installed npm modules)
I have tried this :
import subprocess
import os
dir_path = os.path.dirname(os.path.realpath(__file__)) #holds the directory where python script is located
directory where python script is located
os.chdir(dir_path)
subprocess.call(["npm","init"])
subprocess.call(["npm","install"])

try this code in the test.py script, package.json should be present in the same folder while running the python script
This worked for me!

os.chdir(dir_path)
subprocess.check_call('npm init', shell=True)
I run pip install streamlit and succesfully install streamlit.
However, when I run streamlit hello or streamlit run app.py where app.py is a python app where I import streamlit, I get the following error.

I have tried to disable firewall but still got the error persists. I have also tried running streamlit run app.py --browser.serverPort 3000 and still got the same error.
I think the option is not --browser.serverPort but --server.port:
streamlit run your_script.py --server.port 3000

I just updated my machine to Mountain Lion (10.8.1) and am trying to install vim-latex. I have used the suite daily for about 5 years now, but when trying to do a clean install and opening up a .tex file I get the following error message.

This appears to be a problem with the Python implementation. Are there any suggestions how to fix this?
