VS Code automatic npm build fails with "npm command not found"

vscode tasks

vscode run task shortcut

According to docs it is supposed to work. When I press Ctrl-Shift-B, I do get npm: build as an option, which if I run I get npm command not found in the terminal. However, manually running npm run build works.

I am using nvm. Some relevant outputs:

 ~  which node
/home/gt/.nvm/versions/node/v10.15.3/bin/node
 ~  which npm 
/home/gt/.nvm/versions/node/v10.15.3/bin/npm
 ~  echo $NODE_PATH
/home/gt/.nvm/versions/node/v10.15.3/bin/node

What could be the reason for this? And how to fix it?

The issue is likely because npm isn't in VS Code's path (likely /usr/bin). However, you can create a custom build task and specify the path. In the .vscode directory, create a tasks.json file. Place the contents below in the file.

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "npm:build",
            "type": "shell",
            "group": { "kind": "build", "isDefault": true },
            "command": "/home/gt/.nvm/versions/node/v10.15.3/bin/npm run build"
        }
    ]
}

The group setting makes this task the default and a build-style task in VS Code. Thus, it enables it to be launched from ctrl+shift+b.

Self-answering because I finally found the two things I needed to do:

  1. Create a tasks.json as explained in one answer:

    {
        "version": "2.0.0",
        "tasks": [
            {
                "label": "npm:build",
                "type": "shell",
                "group": { "kind": "build", "isDefault": true },
                "command": "/home/gt/.nvm/versions/node/v10.15.3/bin/npm run build"
            }
        ]
    }
    

    After this I got another error saying: "/usr/bin/env: node: No such file or directory"

  2. Then I found this github thread, and so I created symlink as per suggestion:

    $ sudo ln -s /home/gt/.nvm/versions/node/v10.15.3/bin/node /usr/bin/node
    

and the ctrl+shift+b shortcut works now. Note that the source argument in your case can be got from which node.

Configure npm script shell for running npm tasks in VS Code. · Issue , GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. Sign up. Create 2 tasks with "type": "npm" and same "script" Expected both tasks to be resolved by their label. VsCode will list only one of those tasks when listing available tasks with "Tasks: Run Task". Depending tasks will fail with "Couldn't resolve dependent task 'x' in workspace folder 'y'" in the "Tasks" output. tasks.json:

I am using nvm and wrote a wrapper script that reads the node version from .nvmrc. This avoids hardcoding a specific node version in multiple places. The wrapper script is configured for all shell commands in settings.json using the terminal.integrated.automationShell.<os> setting.

#!/bin/bash

set -e

if [[ "$2" == nvm* ]]; then
    export NODE_VERSION=v$(cat .nvmrc)
    if [ -z "$NODE_VERSION" ]; then
        echo "$(pwd)/.nvmrc does not exist or is empty"
        exit 1
    fi
    CLEAN_CMD=$(echo $2 | sed -e 's/nvm/npm/g')

    /bin/bash -c "~/.nvm/nvm-exec $CLEAN_CMD"
else
    /bin/bash -c $@
fi

A task can then use the correct node version using the nvm <command> command:

    {
        "type": "shell",
        "command": "nvm run compile",
        "label": "npm-compile",            
        "problemMatcher": "$tsc",
        "isBackground": false,  
        "presentation": {
            "reveal": "always"
        },
        "group": {
            "kind": "build",
            "isDefault": true
        }
    }

npm ci fails due to files being kept open by vscode · Issue #72535 , Run NPM scripts in Visual Studio Code with a Single Click NPM scripts in No problem can be solved by the same kind of thinking that created it which you can run with npm <command>, for example npm install or npm test. VS Code will now automatically search for your package.json file and extract  D:\git\PlatformWeb\ClientApp [qa ≡]> npm ci npm WARN prepare removing existing node_modules/ before installation npm ERR! path D:\git\PlatformWeb\ClientApp ode_modules\@angular-devkit\build-angular npm ERR! code EPERM npm ERR! errno -4048 npm ERR! syscall unlink npm ERR!

We solved this by sourcing file where NVM is setup and then running npm commands.

Example:

"command": "source scripts/nvm && npm run develop",
# ./scripts/nvm

# This is for users who don't have a global Node.js installation but instead
# rely on NVM. This file is sourced when running build tasks in non-login
# shells.

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm

Alternatively you can source ~/.bash_profile (or any other file) here. We feel this is a better alternative than hardcoding nvm's npm path.

Run NPM scripts in Visual Studio Code with a Single Click, The easiest way to install TypeScript is through npm, the Node.js Package Another benefit of using VS Code tasks is that you get integrated error and Tip: The tsc compiler does not detect the presence of a jsconfig.json file automatically. I just dealt with a similar problem. If all else fails, you can always use the MSBuild.exe in command prompt to build a projects. Open "Developer Command Prompt" for your version of Visual Studio. In the case of VS 2013, it is located here (C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Tools\Shortcuts)

I think you are not in the right directory.

Try the below method.

Open any ts/html file from any component the do the same (Ctrl+Shift+B).

Probably it will work, it's work for me.

TypeScript Compiling with Visual Studio Code, npm allows you to install and manage packages for use in your Node.js applications. Visual Studio makes it easy to interact with npm and issue npm From existing Node.js code solution template or the Open folder (Node.js)  I was previously using gulp and running gulp to start my application and listeners from the Visual Studio Code debugger but have recently needed to switch to running scripts through npm instead. Unfortunately in VSCode I've not been able to run npm scripts through the debugger so I've had to resort to running node to start my server directly

Manage npm packages, Here are my top picks for Visual Studio Code extensions for Node.js developers. When I initialize a new Node.js project folder, the first thing I install from the terminal is ESLint. parserOptions: { ecmaVersion: 2018 }, rules: { indent: [ "error​", "tab" ] ESLint extension automatically fixes issues on save  When your npm start fails, it is probably because you called npm clean or similar to delete the latest build so your application file is not present causing npm start to fail. npm build's source code - to touch on the discussion in this question - is in github for you to have a look at if you like.

  • Are you using the default tasks? or did you create a tasks.json?
  • I did not create a tasks.json, but according to the docs, straight up ctrl shift b should work.
  • Have you tried it without the tasks.json file? My guess is that if it was a path issue, it got resolved by the symlink anyway. For future, you can use which node inside the ln command. ln -s "$(which node)" /usr/bin/node
  • @technogeek1995 Hey, thanks but it doesn't work without the tasks.json file, instead says npm command not found.
  • I think am in the right directory. I have my package.json and package-lock.json in that directory at the top level, alongside node_modules and the gulpfile.js
