# This install script is intended to download and install the latest available
|
||||
# release of the wasmer.
|
||||
# Installer script inspired from:
|
||||
# 1) https://raw.githubusercontent.com/golang/dep/master/install.sh
|
||||
# 2) https://sh.rustup.rs
|
||||
# 3) https://yarnpkg.com/install.sh
|
||||
# 4) https://raw.githubusercontent.com/brainsik/virtualenv-burrito/master/virtualenv-burrito.sh
|
||||
#
|
||||
# It attempts to identify the current platform and an error will be thrown if
|
||||
# the platform is not supported.
|
||||
#
|
||||
# Environment variables:
|
||||
# - INSTALL_DIRECTORY (optional): defaults to $HOME/.wasmer
|
||||
# - WASMER_RELEASE_TAG (optional): defaults to fetching the latest release
|
||||
# - WASMER_OS (optional): use a specific value for OS (mostly for testing)
|
||||
# - WASMER_ARCH (optional): use a specific value for ARCH (mostly for testing)
|
||||
#
|
||||
# You can install using this script:
|
||||
# $ curl https://raw.githubusercontent.com/WAFoundation/wasmer/master/install.sh | sh
