Zsh: command not found: webpack

问题:

I'm learning React and installed webpack through npm to my project directory but zsh is not finding the command even though I can see webpack installed in my project. I used npm init --yes followed by npm install --save webpack

回答1:

Install it globally.

npm i -g webpack

If you will work with webpack, install webpack-dev-server too

npm i -g webpack-dev-server

I recommend you first learn a bit about npm and then webpack. You will struggle a lot. And then i recommend not using webpack at all. I found it redundant like bower. I am sticking my gulp build and npm. Actually NPM does all but a bit hard to figure. Gulp makes it a lot easier.

回答2:

having webpack installed locally, you could also use:

$(npm bin)/webpack

instead of:

./node_modules/.bin/webpack

回答3:

Installing node modules globally is a quick solution, but i recommend to add ./node_modules/.bin to the path variable and try to understand, what's the problem.

Execute

~ export PATH="./node_modules/.bin:$PATH"

Afterwards you can simply use all packages installed locally in your project. Also commands like mocha or eslint can be executed without installing these packages globally. There are several good explanations out there maybe also read this answer.

回答4:

There is no need to install webpack globally.

Try my way:

First, in your package.json file, add this:

"scripts": {    "start": "webpack" },

Then, in your terminal, run

$npm start

Another quick way: Just run (Yes, it is 'npx')

$npx webpack

That's all.

回答5:

In my case I had this problem with webpack, grunt and gulp and seems that my problem was an issue with permissions.

I installed webpack and grunt globally. However, even then, $ webapack or $ grunt resulted in command not found

The problem was that npm installed the global packages to /usr/local/lib/node_modules which required root permissions.

So, to avoid having to use root permissions, I changed the directory in which global packages are to be installed to a directory in $HOME. To do this, I followed this guide:

Install npm packages globally without sudo on macOS and Linux

After this, I installed webpack and grunt globally again (this time without sudo) and verified that they have been installed in my new directory.

Now, I can run without problem!

$ webpack

and

$ grunt
