Apache Druid startup script requires Python2 or Python3 interpreter.
|
|
Since Python2 is deprecated, this document has instructions to install Python3 interpreter.
|
|
|
|
## Python3 interpreter installation instructions
|
|
|
|
### Linux
|
|
|
|
#### Debian or Ubuntu
|
|
- `sudo apt update`
|
|
- `sudo apt install -y python3-pip`
|
|
#### RHEL
|
|
- `sudo yum install -y epel-release`
|
|
- `sudo yum install -y python3-pip`
|
|
|
|
### MacOS
|
|
|
|
#### Install with Homebrew
|
|
Refer [Installing Python 3 on Mac OS X](https://docs.python-guide.org/starting/install3/osx/)
|
|
|
|
#### Install the official Python release
|
|
* Browse to the [Python Downloads Page](https://www.python.org/downloads/) and download the latest version (3.x.x)
