FileNotFoundError: [Errno 2] No such file or directory: '/path/to/file.txt' Why it happens
This error occurs when the code attempts to open or access a file or directory path that does not exist on the file system or is incorrectly specified. It can also happen if the path is inaccessible due to permissions or if the path string is malformed.
Detection
Add checks using os.path.exists(path) before file operations or catch FileNotFoundError exceptions to log missing paths and prevent crashes.
Causes & fixes
The file path provided to the E2B API does not exist on the local file system.
Verify the file path is correct and the file exists before calling E2B functions that access it.
The file path is relative but the current working directory is different than expected.
Use absolute paths or ensure the working directory is set correctly before accessing files.
Insufficient permissions prevent reading the file or directory at the specified path.
Check and update file system permissions to allow read access for the running process.
The path string contains typos, invalid characters, or escape sequences that alter the intended path.
Sanitize and validate path strings, use raw strings (r'path') or pathlib.Path objects to avoid escape issues.
Code: broken vs fixed
import e2b
file_path = '/path/to/file.txt'
e2b.load_file(file_path) # triggers FileNotFoundError if path missingimport os
import e2b
file_path = '/path/to/file.txt'
if os.path.exists(file_path):
e2b.load_file(file_path) # fixed: check path before loading
else:
print(f"Error: File not found at {file_path}")Workaround
Wrap the file access call in try/except FileNotFoundError, then log the missing path and skip or fallback gracefully.
Prevention
Use absolute paths, validate file existence early, and handle missing files gracefully in your e2b integration to avoid runtime crashes.
