How do I open files to read/write in Mojo?
When you call a function, which throws an exception you need either to catch and handle it or define in your function by using key 'raises' its given to its caller to handle it.

It's a working example .. you may add raises to your main function ?

from pathlib.path import cwd
from pathlib.path import Path

from python import Python

fn main() raises:
    let currentPath = cwd()
    let file = currentPath/"my_file.txt"
    
    with open(file, "w") as f:
        f.write("Hello, world!")

    with open(file, "r") as f:
        print(f.read())

    let os = Python.import_module("os")
    os.remove(file.path)

Maybe you can try it without the export. Just echo 'key="value"' >> $GITHUB_PATH echo 'MODULAR_HOME="/home/runner/.modular"' >> $GITHUB_PATH echo 'PATH="/home/runner/.modular/pkg/packages.modular.com_mojo/bin:$PATH"' >> $GITHUB_PATH

Mojo Install Hanging in Codespaces
Had the same issue. I interrupted installer (by pressing CTRL+C) and setup env variables ... echo 'export MODULAR_HOME="$HOME/.modular"' >> ~/.bashrc echo 'export PATH="$MODULAR_HOME/pkg/packages.modular.com_mojo/bin:$PATH"' >> ~/.bashrc source ~/.bashrc and after that i could run mojo.
