I am working with webpack and I need to execute ./node_modules/webpack/bin/webpack.js using npx. npx webpack would run the webpack binary (./node_modules/webpack/bin/webpack), but each time I execute npx webpack I getbash: npx: command not found.
I am using:
node: v9.5.0
npm: 5.6.0
nvm: 1.1.5
webpack: 3.11.0

npx should come with npm 5.2+, and you have node 5.6 .. I found that when I install node using nvm for Windows, it doesn't download npx. so just install npx globally:
npm i -g npxIn Linux or Mac OS, if you found any permission related errors use sudo before it.
sudo npm i -g npxif you are using Linux system, use sudo command
sudo npm i -g npxRemove NodeJs and npm in your system and reinstall it with the following commands:
Uninstallation
sudo apt remove nodejs
sudo apt remove npmFresh Installation
sudo apt install nodejs
sudo apt install npmConfiguration optional, in some cases users may face permission errors.
user defined directory where npm will install packages
mkdir ~/.npm-globalconfigure npm
npm config set prefix '~/.npm-global'add directory to path
echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.profilerefresh path for the current session
source ~/.profilecross-check npm and node modules installed successfully in our system
node -v npm -v
Installation of npx
sudo npm i -g npx
npx -vWell done, we are ready to go. Now you can easily use npx anywhere in your system.
check versions of node, npm, npx as given below. if npx is not installed then use npm i -g npx
node -v
npm -v
npx -vif you are using macOS, use sudo command
sudo npm install -g npxUpdating node helped me, whether that be from the command line or just re-downloading it from the web
I returned to a system after a while, and even though it had Node 12.x, there was no npx or even npm available. I had installed Node via nvm, so I removed it, reinstalled it and then installed the latest Node LTS. This got me both npm and npx.
sudo apt install npminstall npm first
(it will take around 177MB node also will get installed along with this cmd) space
Install npxsudo npm i -g npx
Check the version of the installed npm,node,npx (for confirming latest release and installed or no it will show) usingnod -v npx -v npm -v
1. First step:check and install your node version with node -v.
2. second step:check and install your npm version with npm -v.
If you still have a problem,might your command is npx create_react_app your_app_name instead of npx create-react-app your_app_name.
check node -v,npm -v, npx -v if are you getting output in the terminal but if you are executing these commands inside terminal of any IDE's like VSCODE, ATOM ... etc then reinstall that IDE.
- I went to the documentation of vs-code (mentioned below on recourses section)
- Initially they ask to check the execution policy by executing
Get-ExecutionPolicyon power shell of vs-code -> I got Restricted - Next
Get-ExecutionPolicy -Listto get all of the execution policies with their scorps. And I got the follwing result :/
MachinePolicy Undefined
Process Undefined
CurrentUser Undefined
LocalMachine Undefined
Then I rechecked the error which was displayed at the beginning, in vs-code power shell
'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied. To change the execution policy
execution policy for the current user, run "Set-ExecutionPolicy -Scope CurrentUser".In there too it's mentioned the err is about the current-user
So I execute
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUserAnd it worked for me. It's pleasure if this would work to you too thanks.
Recourses:
try :
sudo suthen
npm i npx
or
npi i -g npxcheck your npx version by
npx -v
