Node.js® 是一个基于 Chrome V8 引擎 的 JavaScript 运行时环境。

参考文档：https://github.com/nodesource/distributions/blob/master/README.md#debmanual

  1. # add-apt-repository may not be present on some Ubuntu releases:
  2. # sudo apt-get install python-software-properties
  3. sudo add-apt-repository -y -r ppa:chris-lea/node.js
  4. sudo rm -f /etc/apt/sources.list.d/chris-lea-node_js-*.list
  5. sudo rm -f /etc/apt/sources.list.d/chris-lea-node_js-*.list.save
  1. KEYRING=/usr/share/keyrings/nodesource.gpg
  2. curl -fsSL https://deb.nodesource.com/gpgkey/nodesource.gpg.key | gpg --dearmor | sudo tee "$KEYRING" >/dev/null
  3. # wget can also be used:
  4. # wget --quiet -O - https://deb.nodesource.com/gpgkey/nodesource.gpg.key | gpg --dearmor | sudo tee "$KEYRING" >/dev/null
  5. gpg --no-default-keyring --keyring "$KEYRING" --list-keys
  1. # Replace with the branch of Node.js or io.js you want to install: node_6.x, node_8.x, etc...
  2. VERSION=node_8.x
  3. # Replace with the keyring above, if different
  4. KEYRING=/usr/share/keyrings/nodesource.gpg
  5. # The below command will set this correctly, but if lsb_release isn't available, you can set it manually:
  6. # - For Debian distributions: jessie, sid, etc...
  7. # - For Ubuntu distributions: xenial, bionic, etc...
  8. # - For Debian or Ubuntu derived distributions your best option is to use the codename corresponding to the upstream release your distribution is based off. This is an advanced scenario and unsupported if your distribution is not listed as supported per earlier in this README.
  9. DISTRO="$(lsb_release -s -c)"
  10. echo "deb [signed-by=$KEYRING] https://deb.nodesource.com/$VERSION $DISTRO main" | sudo tee /etc/apt/sources.list.d/nodesource.list
  11. echo "deb-src [signed-by=$KEYRING] https://deb.nodesource.com/$VERSION $DISTRO main" | sudo tee -a /etc/apt/sources.list.d/nodesource.list
  1. sudo apt-get update
  2. sudo apt-get install nodejs
