JSON Errors

Use This Guide When

Before You Run Anything

• Copy the complete error, including the first package, file, module, or line number it names.
• Record `termux-info`, the active language/runtime version, and the current folder before changing dependencies.
• Do not delete package-manager locks or upgrade pip itself through pip in Termux.

Diagnostic Or Setup Commands

Replace placeholders before running a line. Use Termux package names and stop at the first error instead of repeating the whole block.

python -m json.tool data.json > /tmp/checked.json
python - <<'PY'
import json
json.load(open("data.json", encoding="utf-8"))
print("JSON OK")
PY

What The Commands Tell You

• `python - <<'PY'` — Runs an inline Python diagnostic.

What Success Looks Like

• The minimal version, import, syntax, path, or package test exits successfully.
• The original command now fails later for a different, clearly identified reason or completes normally.
• The package manager has no interrupted configuration left pending.

Safe Next Steps

1. Repair or update the Termux package layer before retrying a language package.
2. Confirm that the interpreter and its package tool belong to the same installation.
3. Install the missing system dependency before repeating a Python or Node build.
4. Retest with a minimal version, import, compile, or file command before running the full script.

Common Mistakes

• Using `sudo`, Ubuntu package names, or desktop paths in a normal Termux installation.
• Assuming that a Python import name always matches the distribution name on PyPI.
• Deleting caches, environments, or lock files before preserving the exact error and versions.
