Heroku：将节点更新到最新版本

Question

I would like to update my node version to latest version possible on my local machine. I am using Ubuntu 16.04. I am currently finding trouble to update with methods available to my best of knowledge . Please note that heroku-cli is up to date(as of yet).

$ check-node-version
node: 8.3.0
npm: 5.4.2
yarn: 1.2.1

Here are other important commands which may help

harman@manchanda: 04:14 pm ~ $ node -v
v8.3.0

harman@manchanda: 04:14 pm ~ $ which node
/usr/local/heroku/bin/node

harman@manchanda: 04:15 pm ~ $ nodejs -v
v8.7.0

harman@manchanda: 04:15 pm ~ $ which nodejs
/usr/bin/nodejs

harman@manchanda: 04:15 pm ~ $ heroku -v
heroku-cli/6.14.34-1fcf80e (linux-x64) node-v8.6.0

harman@manchanda: 04:15 pm ~ $ n
node/6.2.2
node/6.7.0
node/7.0.0
node/7.8.0
node/7.9.0
node/8.4.0
node/8.7.0

Let me know if any other information is needed for same?

Answer 1

Assuming you have installed n package on your local machine, you can run

sudo n latest

to update Node to the latest version available (8.7.0 at the moment of writing this answer)

Or, if you want to use the latest Node in your heroku dyno:

1. Open your local project's root
2. Open package.json

3. Add "engines": { "node": "8.7.0" }, like that:

   { "name": "node-example", "version": "1.0.0", "description": "This example is so cool.", "main": "web.js", "scripts": { "test": "echo \\"Error: no test specified\\" && exit 1" }, "keywords": [ "example", "heroku" ], "author": "jane-doe", "license": "MIT", "engines": { "node": "8.7.0" }, }

4. git add package.json && git commit -m "Specified node version"

5. git push heroku master
