jlenv installer & doctor scripts

jlenv-installer

The jlenv-installer script idempotently installs or updates jlenv on your system. If Homebrew is detected, installation will proceed using brew install/upgrade. Otherwise, jlenv is installed under ~/.jlenv.

Additionally, julia-build is also installed if jlenv install is not already available.

# with curl
curl -fsSL https://raw.githubusercontent.com/jlenv/jlenv-installer/master/libexec/jlenv-installer | bash

# alternatively, with wget
wget -q https://raw.githubusercontent.com/jlenv/jlenv-installer/master/libexec/jlenv-installer -O- | bash

jlenv-doctor

After the installation, a separate jlenv-doctor script is run to verify the success of the installation and to detect common issues. You can run jlenv-doctor on your machine separately to verify the state of your install:

# with curl
curl -fsSL https://raw.githubusercontent.com/jlenv/jlenv-installer/master/libexec/jlenv-doctor | bash

# alternatively, with wget
wget -q https://raw.githubusercontent.com/jlenv/jlenv-installer/master/libexec/jlenv-doctor -O- | bash
