I have a laravel project and I need to build styles and scripts with laravel-mix, but a testing server (Ubuntu 20.04.4) hasn't a globally installed node. Node and npm are in different folders in the system so I run commands like this:
/path/to/node /path/to/npm install
/path/to/node /path/to/npm run dev
But when I run npm run dev (this command runs laravel-mix build), I see the error:
> mazer#2.0.0 dev
> mix
/usr/bin/env: ‘node’: No such file or directory
In the package.json it looks like this:
"scripts": {
"dev": "mix"
...
}
I checked the laravel-mix package (in node_modules) and found this: #!/usr/bin/env node. The package checks the node var in this file, but there is no node var.
I don't need to change the env file, so how can I change this path or set a temporary system var? Is there any way to simulate that the variable is there?
I have one solution for this problem.
The issue regarding naming misspelling or path symlinks.
so that you need to link symlinks for nodejs with this command
ln -s /usr/bin/nodejs /usr/bin/node
or
sudo ln -s /usr/bin/nodejs /usr/bin/node
I resolved my issue with Docker, so now I run this command on git push:
docker run --rm -v /path/to/project:/var/www/html node:16.16.0-alpine npm run dev --prefix /var/www/html
Perhaps it will be useful to someone.
UPD
I found another way to resolve it, I use PATH incorrectly and for this reason it didn't work:
Wrong
I set paths to node and npm and then add it to PATH like this:
NODE_PATH="/path/to/node_folder/node"
NPM_PATH="/path/to/node_folder/npm"
PATH="${NODE_PATH}:${NPM_PATH}:$PATH"
And the system can't find npm and node anyway.
The right way
Add /path/to/node_folders (node and npm are in it) to PATH:
NODE_DIR="/path/to/node_folder"
PATH="${NODE_DIR}:$PATH"
And then, I can run just npm install and npm run dev without full paths to them.

Created new folder and did npm install serve in it.
It created package-lock.json and node_modules/ folder.
When I run in the same folder serve it shows error:
command not found: serve
What is the way to install?
I am using: npm#6.5.0
My dev environment is MACOS
I read a great many pages on this topic and nothing worked until I tried the following
./node_modules/.bin/serve -s build
Also if you are using VS CODE you may want to bring up the terminal window outside of VS CODE - this seems to have snared a lot of people.
First of all, you should start your project running
npm init
This will create the package.json file.
Then, you can install the serve package globally.
npm install -g serve
And now you can run serve.
The serve binary was not found because the operating system cannot locate it in the PATH environment variable.
When you do the npm install serve command. The serve module is only installed into the node_modules directory found under the the project folder. Unless you explicitly include the absolute path of this node_module directory as part of your PATH env var, the OS won't know where to find serve.
Like others say, the typical practise would be to install the module using the -g flag. G means global.
When -g is used, npm will put the binary in its node directory somewhere and this this directory would have been included as part of your PATH when you install node, thus making the any new binary discoverable.
If the node.js module has a "command" and you want to run it without installing the module globally(npm install -g serve). You can run it like ./node-modules/.bin/command from the root folder of the project.
Now, what is generally used is npx, so that you can from within a project easily run any of the binaries within its local node_modules or your system's global node_modules/ and any other commands on the $PATH.
For example, here we install webpack as a local dependency. You can image doing this in a folder after running npm init. Then we run webpack without having to worry about referencing the bin file:
$ npm i -D webpack
$ npx webpack
I would like to know whether it is possible somehow to run a node.js command line app without using the global folder, i.e. no npm install -g or npm link.
If you want to use a cli that is npm installed locally without using anything else, you can do (assuming webpack):
node ./node_modules/.bin/webpack
Just check that directory ./node_modules/.bin
Probably npx would work for you.
$ npm i -D webpack
$ npx webpack ...
I ran the following command for my node app:
$ npm install browser-sync --save-dev
Installation was successful, browser-sync appears in my package.json file as well as my node_modules directory.
However, when I run $ browser-sync --version to check that it's working, I get the following error:
bash: browser-sync: command not found
Why isn't this working?
Note: this question is similar, but I don't want to have to install it globally as in this question.
Any help would be greatly appreciated!
This is because you're trying to use a module locally which is normally installed globally. Modules installed globally end up on your PATH environment variable, which is why you can run them from the terminal as you're trying to do:
$ browser-sync --version
If you want to use the browser-sync module from a local install you will have to prepend the full path to the browser-sync binary from within your .bin directory since all locally installed modules are placed within your current working directory node_modules directory. i.e. Node modules go in ./node_modules, executables go in ./node_modules/.bin/. So in order to run the browser-sync binary from a local install do the following:
./node_modules/.bin/browser-sync --version
Hopefully that helps!
If you installed browser-sync using npm --save or npm --save-dev you can run it by writing a script in your package.json. Here's an example of a script I added:
{
...
"scripts": {
"dev-server": "browser-sync start --server 'public' --files 'public'"
},
...
}
You can run the scripts from you project's root directory like so
npm run dev-server
This will run whatever command is set to dev-server in your script. In this case it will run browser-sync for the app/site in a folder called /public and watch for any file changes in the /public folder. I know this question is a bit old but it was unanswered and hopefully I can save someone time in the future.
The other answers still work, but a newer approach has emerged since npm added the npx command: npx <package-name>.
This command allows you to run an arbitrary command from an npm
package (either one installed locally, or fetched remotely), in a
similar context as running it via npm run.
Source: https://docs.npmjs.com/cli/v8/commands/npx
In this case, you would run npx browser-sync.
I'm running this command on linux:
sudo npm install -g webpack
I'm getting the following output:
/home/igor/.npm-global/bin/webpack ->
/home/igor/.npm-global/lib/node_modules/webpack/bin/webpack.js
/home/igor/.npm-global/lib └── webpack#1.13.3
which looks perfectly legit, but when I try to use:
webpack -h
I get the
webpack: command not found
How can I make webpack running from the command prompt?
The default directory for globally installed NPM modules is /usr/local, which will install the module binaries inside bin folder.
If you echo your $PATH environment variable you'll see that /usr/local/bin is in your path. That means when you run a command like webpack, macOS will try to find the binary in this folder or any other folder on your $PATH.
At some point you probably changed it to ~/.npm-global, which installed webpack binary into your /home/igor/.npm-global/bin/. As this folder is not in you $PATH, macOS did not find it. You can run npm config get prefix to confirm this.
Solution 1 is to add it to your path by changing your ~/.profile file. Just append export PATH=~/.npm-global/bin:$PATH to it and restart your terminal.
Solution 2 is to change back the default folder to /usr/local by running npm config set prefix '/usr/local'. In this case you won't need to change your PATH variable.
Try to install webpack localy on the path you're working with.
I have a problem on npm installation
I have created a project say project A
cd ~/projectA
npm install sails
but sails command is not found after installation.
I know that it is successfully install in ~/projectA/node_modules directory.
but the executable cannot be sourced. And i know it is installed ~/projectA/node_modules/.bin
How can I source the .bin automatically whenever I enter into this projectA folder?
Did I did something wrong?
I can give you an inelegant solution, which is working for me. I just exported my path in my .bashrc file.
export PATH="$PATH:./node_modules/.bin"
Edit: It's been a while, but I have changed my strategy to use npm scripts instead. In the above case, setup package.json as follows:
"scripts": {
"sails": "sails"
}
Which you can then run with
npm run sails
or with arguments
npm run sails -- <args>
You should use the npm bin command to get an absolute path to your current node bin directory.
For example:
➤ lessc
bash: lessc: command not found
➤ npm bin
/home/brice/[...]/node_modules/.bin
➤ export PATH=$(npm bin):$PATH
➤ lessc --version
lessc 1.7.3 (Less Compiler) [JavaScript]
This avoids the problem of relative paths, especially if you're going to be using this in a build system that will invoke the command in subdirectories.
A bit more robust is:
export PATH=$(npm bin):$PATH
You can either run it, add it to your shell profile, or create an alias like:
alias snpm='export PATH=$(npm bin):$PATH'
If you do go the alias route, be sure to use single quotes so it delays the execution of the variables!
To use on the command line like sails generate foo you will need to install the npm module globally.
npm install -g sails
You could also use the path to the bin in the command if you don't want to install globally:
./node_modules/sails/bin/sails.js generate foo
The official instructions for sails (https://github.com/balderdashy/sails) advises
To install the latest stable release with the command-line tool:
sudo npm -g install sails
This installs globally and adds to a directory like /usr/local/bin that should be in your $PATH.
But to answer the general question regarding the location of the binaries if you install locally, they should be placed in ./node_modules/.bin directory (so run ./node_modules/.bin/sails ...)
If you don't like to mess up with your PATH for running a npm script that isn't global -- e.g. you are the only one to use it --, I would personally recommend the use of an sh "alias".
npm install (locally) your beloved package (json-diff here, for instance)
cd ~ && npm install json-diff
alias it (save it in your ~/.xxxxrc file):
alias diffj "\`npm bin\`/json-diff !*"
Then, for diffing 2 json's:
diffj old.json new.json
In my ~/.bashrc, I have the following:
function nbin {
local dir;
dir=$(npm bin)
if [ -d "$dir" ]; then
( # subshell to not change this shell's $PATH
PATH=$dir:$PATH
eval "$#"
)
else
echo "\"$dir\" is not an npm binary directory." >&1
return 1
fi
}
I can then run executable foo in the .bin directory as:
nbin foo
Possible workaround with NPM 5.2+ using the npx command.
npx sails new test-project
