This article helps you to solve the installation problems of Jina.

On Linux/Mac, building wheels takes long time#

The normal installation of Jina takes 10 seconds. If yours takes longer than this, then it is likely you unnecessarily built wheels from scratch.

Every upstream dependency of Jina has pre-built wheels exhaustively for x86/arm64, macos/Linux and Python 3.7/3.8/3.9, including numpy, protobuf, grpcio etc. This means when you install Jina, your pip should directly leverage the pre-built wheels instead of building them from scratch locally. For example, you should expect the install log to contain -cp38-cp38-macosx_10_15_x86_64.whl when installing Jina on macOS with Python 3.8.

If you find you are building wheels during installation (see an example below), then it is a sign that you are installing Jina wrongly.

Solution: update your pip#

It could simply be that your local pip is too old. Updating it should solve the problem:

pip install -U pip

If not, then…#

Then you are likely installing Jina on a less-supported system/architecture. For example, on native Mac M1, Alpine Linux, or Raspberry Pi 2/3 (armv6/7).

On Windows with conda#

Unfortunately, conda install is not supported on Windows. You can either do pip install jina natively on Windows, or use pip/conda install under WSL2.

Upgrading from Jina 2.x to 3.x#

If you upgraded an existing Jina installation from 2.x to 3.x you may see the following error message:

OSError: `docarray` dependency is not installed correctly, please reinstall with `pip install -U --force-reinstall docarray`

This can be fixed by reinstalling the docarray package manually:

pip install -U --force-reinstall docarray

To avoid this issue in the first place, we recommend installing Jina in a new virtual environment instead of upgrading from an old installation.
