I can't install nestjs in ubuntu 20.04-CodePudding

I'm using Ubuntu 20.04 LTS and I was trying to install nestjs to study but... well, it's better to show what happened

first I tried to discover which version of my npm or node was, that was the result:

$ npm - v

output: 6.14.16

$ node -v

output: v14.19.1

theoretically I can install nest, right? well, I ran this code:

$ npm i -g @nestjs/cli

output: /home/user/.npm-global/bin/nest -> 
/home/user/.npm-global/lib/node_modules/@nestjs/cli/bin/nest.js
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@~2.3.2 (node_modules/@nestjs/cli/node_modules/chokidar/node_modules/fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})

  @nestjs/[email protected]
updated 1 package in 17.045s

I figured that this output seemed weird, even so I tried to discover if nest was installed

$ nest -v

output: Command 'nest' not found, did you mean:

  command 'newt' from snap newt (0.0.1)
  command 'net' from deb samba-common-bin (2:4.13.17~dfsg-0ubuntu0.21.04.1)
  command 'next' from deb mailutils-mh (1:3.7-2.1)
  command 'next' from deb mmh (0.4-2)
  command 'next' from deb nmh (1.7.1-6)
  command 'test' from deb coreutils (8.30-3ubuntu2)
  command 'nast' from deb nast (0.2.0-7build1)
  command 'neat' from deb neat (2.2-1build1)
  command 'nes' from deb fceux (2.2.2 dfsg0-1build1)
  command 'nes' from deb mednafen (1.22.2 dfsg-1build1)
  command 'nes' from deb nestopia (1.50-1build1)

See 'snap info <snapname>' for additional versions.

I'm really new in this development 'and this is my first post here!' world but I appreciate your attention in my problem (also I'm not from USA so my English might be with lots of mistakes, sorry!)

CodePudding user response：

There are two way to solve your issue:

Use npx before every nestjs command:

  npx @nestjs/cli g controller pages

Add an alias inside your .bashrc or .zshrc (depend which one you are using):

To find your node path, type in your terminal:

  which node

  which nodejs

Then, when you have your path to node:

  alias nest="/your/path/to/node/bin/nest"

Then in your terminal you can test

  nest --version

It should work
