使用g npm install npm @ latest -g更新节点软件包管理器并得到错误

Question

I was trying to update my Node Package Manager using g npm install npm@latest -g in the terminal but when I tried to check if it was updated using npm --version or npm -v or even npm install, I get the following error:

SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode
at exports.runInThisContext (vm.js:53:16)
at Module._compile (module.js:387:25)

at Function.Module.runMain (module.js:447:10)
at startup (node.js:139:18)
at node.js:999:3

I had version 5.0.3 for NPM and now I can't run any npm commands. Can someone please help me remedy this error by uninstalling this latest version or anything to get this version to work.

Block-scoped declarations not yet supported outside strict mode - Laravel Mix , check out this StackOverflow answer. The solution is pretty much to update Node, but I'll explain why. There's a new flavour of Javascript called ES6 (and above) that uses certain keywords that aren't found in your Node version. the new NPM uses these keywords but your older version of Node can't interpret them. Best option is to uninstall and get the latest version.
