ERROR: Could not find a version that satisfies the requirement (from versions: none)
Most likely cause: The package name is misspelled, does not exist on PyPI, or was typed incorrectly in the install command
Try first: Verify the exact package name
Likely causes
- The package name is misspelled, does not exist on PyPI, or was typed incorrectly in the install commandmost likely
- No wheel or source distribution is available for your Python version, operating system, or CPU architecturepossible
- Temporary network problem, PyPI outage, or the package was recently removed or made privateless likely
How to fix it
Verify the exact package nameSafe
Double-check the spelling of the package you are trying to install against the official name on pypi.org. Package names are case-sensitive in some contexts.
Check your Python versionSafe
Run the command below to see which Python version you have. Many packages only support certain versions.
python --versionTry installing with the --upgrade flag or a specific versionChanges settings
If a version exists, forcing an upgrade or pinning an older version can sometimes succeed when the latest does not have a matching distribution.
pip install package-name --upgrade
If that didn't fix it
Search the package name plus your exact Python version and operating system on the web to see if others report the same missing distribution.
When to see a technician
Contact the package maintainer or a Python developer if the package is internal, private, or you need help creating a compatible environment.
Quick answers
- What does ERROR: Could not find a version that satisfies the requirement (from versions: none) mean?
- This is a pip error that occurs when trying to install a Python package. It means pip searched PyPI but found no versions of the requested package that match your setup, so installation fails.
- What causes ERROR: Could not find a version that satisfies the requirement (from versions: none)?
- The package name is misspelled, does not exist on PyPI, or was typed incorrectly in the install command. (most likely) No wheel or source distribution is available for your Python version, operating system, or CPU architecture. (possible) Temporary network problem, PyPI outage, or the package was recently removed or made private. (less likely)
- How do I fix ERROR: Could not find a version that satisfies the requirement (from versions: none)?
