I'm following a tutorial on Solidity and Python (for reference https://www.youtube.com/watch?v=M576WGiDBdQ&t=5447s).
I'm at the stage where Python and Brownie have been installed and running through VSCode, but I am getting the below notification when asking for Brownie's version brownie --version INFO: Could not find files for the given pattern(s). Brownie v1.17.1 - Python development framework for Ethereum
When I try to run an extremely basic script on a file called deploy.py (def main(): print ("hello!") ), here is the result :
PS C:\Users\chret\Documents\demo\brownie_simple_storage> brownie run scripts/deploy.py

I've tried uninstalling and reinstalling from Python to Brownie, changing the place where Brownie's files are, but I'm now stuck due to my very limited knowledge (full beginner).
UPDATE
I've reinstalled Python and pipx and brownie once more, and now the message is slightly different, but still doesn't run the script of deploy.py. The script is :
def main():
print("Hello!")
and the current error message is :
PS C:\Users\chret\Documents\demo\brownie_simple_storage> brownie run scripts.deploy.py

Any help would be greatly appreciated :)
After trying all suggestions, I ended up making it work only by uninstalling and removing every single program and related files.
Uninstalled Python, removed all the files related to Python from my computer, did the same for VSCode, removed all the npm packages, yarn, solc, everything related to the tutorial (I didn't have anything for coding before).
Then, reproduced all the steps until the original post issue, and everything worked fine... A bit frustrating not to know how the issue really got resolved, but it did.
Your deploy script is in the contracts folder/directory.
It needs to be in scripts directory of your project, your brownie_simple_storage/scripts folder.
Try moving it there, and running your script in that folder.
EDIT:
You may need to install nodejs and ganache-cli
I think since brownie is installed via pipx, you have to tell vs code for the path.
ctrl + shift + p
Python: select Interpreter
Find the path in os. this is in linux
~/.local/pipx/venvs/eth-brownie/bin/python
I am using Linux, so find the path in your system and add it there.

I'm trying to run a python script when the system boots on a Windows 10 workstation. My python script runs fine when I kick it off in a different directory as a user with administrative privileges but when I run it from a bat file in the C:\Windows\System32\GroupPolicy\Machine\Scripts\Startup folder on system boot I receive the following error in my logs.

Here is the content of the .bat file.

I have tried using the full nmap.exe path as shown in the code snippet as well as plain old nmap. I get the access denied error either way. I didn't see much in subprocess.py that would lead me to believe this to be an error with the python code either so I am leaning on it being an issue with System user running the script. If someone thinks otherwise or has any ideas, I'd love to hear them. Thanks
EDIT: I chose to run from a bat file because my python version is 32bit and I was having issues running from the C:\windows\system32 directory
It turns out that the path to nmap, C:\Program Files (x86)\Nmap, was not included in the system environment variables. When the script ran as a System user, it did not recognize the location of nmap

This error only happens on one of my 3 machines, so I have no idea what causes it. Resetting to factory defaults or reinstalling docker and vscode doesn't help. Without docker compose the image is pulling and then working fine. All the machines are on windows 10 and latest stable docker installed.
Here is the issue I opened on github. It appeared that this behavior only occurs in VSCode powershell console, but not in regular powershell console. The solution with changing encoding suggested there didn't help.
Solution: Update to 1803 on Windows 10. If you can't update, use external command prompt.
The same thing happens to me with Python scripts. Apparently, this is a Windows Update issue:
https://github.com/Microsoft/vscode/issues/36630#issuecomment-359969098
Edit: My workaround due to my company restricting updates is to use external terminal in VS Code
I'm trying to use PyInstaller to create a standalone OSX app that runs a GUI I've made. When I enter the following in my terminal:

Exception:
Cannot find qt_menu.nib for PyQt4
Path checked:

Which seems strange, since my name is not felipe!
I have a couple of questions:
1) How is it possible that there is a directory under the name felipe on my computer? (I used anaconda to install qt, I don't know whether that has something to do with it?)
2) Up until I get the error message, PyInstaller is looking in the correct folder. Why does it start looking in this vague (vague to me that is) directory I don't know of?
3) I'm quite a novice regarding directories and I can't find mister felipe anywhere on my computer. When I look in the Users folder I just see my own user and an empty "Shared" folder. (I don't know what the shared folder is used for and why it's there.)
4) Based on what I read on the internet, I copied qt_menu-nib to the folder where the script that's supposed to be turned into a standalone is located. What should I do in order to successfully create a standalone from here?
First of all, you face a known issue between PyInstaller and Anaconda: PyInstaller issue #2135. The conversation contains answers to your questions.
1) The path is hardcoded in the wrongly built Qt binary that is provided by Anaconda, see comment from mrady3.
2) PyInstaller loads Qt4-specific hook in order to find resources (qt_menu.nib) that are necessary for running target app. The hook code tries to obtain location of resource directory from the Qt binary itself. Qt binary returns wrong /hardcoded/ path, and after that process fails.
3) See point 1), it was a folder on maintainer's machine. Qt assumes that its installation path is pre-set before building; Anaconda repository hosts a binary that was compiled with another installation path in mind.
4) There could be several possible approaches:
Try installing developer version of PyInstaller from sources, it has some fixes for the above-mentioned issue. Then try building the app again:
git clone https://github.com/pyinstaller/pyinstaller.git
cd pyinstaller
/Users/username/anaconda/bin/python setup.py sdist
conda install dist/PyInstaller-3.3.dev0.tar.bz2
Install Qt4 using homebrew. Local compilation will take a long time:
brew install cartr/qt4/qt
find /usr/local/Cellar/qt -name qt_menu.nib
Edit Qt4 hook at /Users/username/anaconda/lib/python2.7/site-
packages/PyInstaller/hooks/hook-PyQt4.py and replace call to qt_menu_nib_dir('PyQt4') with the path from homebrew installation ('/usr/local/Cellar/qt/4.8.7_3/lib/QtGui.framework/Versions/4/Resources/qt_menu.nib').
Or alternatively, just put qt_menu.nib into expected location:
sudo mkdir -p /Users/felipe/miniconda/envs/_build/lib/QtGui.framework/Resources/
sudo ln -s /usr/local/Cellar/qt/4.8.7_3/lib/QtGui.framework/Versions/4/Resources/qt_menu.nib /Users/felipe/miniconda/envs/_build/lib/QtGui.framework/Resources/
I am using openssh in iron python to run commands from windows to linux. I have installed openssh in both the machines and the service is running. I have added keys in authorized users even
conn = SSHConnection(ip_addr, login=name)
ret = conn.run('ls')
or
ret = conn.run(['ls'])
I am getting error as follows

What is wrong in the code?
The line in my copy is
ssh_command = self.ssh_command(interpreter, forward_ssh_agent)
where interpreter, if not specified, defaults to /bin/bash. I think it's saying it doesn't see /bin/bash on the remote machine.

As obvious,
I am using Windows 7, and have:
Python 2.7.3
JDK
Android Emulator
Device drivers for my Sony Tipo.
Please help!
By the way,
I would prefer to get this running on my phone first. I am thinking of moving to the emulator later(after the tutorial is completed).
Is this question more suitable for https://android.stackexchange.com/?
I am not sure if this is still an issue for you, but I ran into the similar issue recently and managed to solve it so I will just leave a note here.
If anyone gets this kind of error, go to pgs4a folder and android-sdk folder. There, run SDK Manager.exe file. You will see a list of Tools and different android versions. Try to find the version that you are working on and install everything that is 'uninstalled'.
I managed to solve the above issue by installing everything under my current AND previous Android versions. Hope this will help anyone who ran into the same issue!
rename the folder android-sdk-windows to android-sdk
