# ERROR: Invalid requirement: 'requests=>2.0' (from line 1 of requirements.txt)
Hint: = is not a valid operator. Did you mean == ?

- **ID:** `python/invalid-requirement-parse`
- **Domain:** python
- **Category:** data_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

A typo in requirements.txt uses `=>` instead of `>=` or `==`. pip's requirement parser rejects the malformed version specifier.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 3.x | active | — | — |

## Workarounds

1. **** (95% success)
   ```
   Fix the operator in requirements.txt:
sed -i 's/=>/>=/g' requirements.txt
pip install -r requirements.txt
   ```
2. **** (85% success)
   ```
   Validate requirements before install:
python -m pip install --dry-run -r requirements.txt
   ```

## Dead Ends

- **** — The parse error occurs before dependency resolution; --no-deps does not bypass parsing. (90% fail)
- **** — Upgrade flag does not change parsing; the same line fails. (90% fail)
