我无法在ubuntu16.04上运行nodejs

Question

I have installed nodejs on my ubuntu16.04 . But I can't run this. When I write a command npm run dev it shows the following error:

---

> node node_modules/cross-env/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

module.js:472
    throw err;
    ^

Here I have also installed npm-debug .log using the below command but still I'm facing this problem

npm install --save debug-log enter image description here

Answer 1

Using npm install installs the module into the current directory only (in a subdirectory called node_modules).

This guide was very helpful to me as well: https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-ubuntu-16-04

Answer 2

It's a problem in the package.json "scripts" configuration. Either replace the "scripts" section in your package.json file with the following:

"dev": "cross-env NODE_ENV=development webpack --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"watch": "cross-env NODE_ENV=development webpack --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"hot": "cross-env NODE_ENV=development webpack-dev-server --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
"production": "cross-env NODE_ENV=production webpack --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"

Then re-install the node modules.

Or, as another option, follow Jeffrey Way's advice found at the bottom of the following cross-env issue page .

Answer 3

I had same problem when upgraded cross-env package.

Previously it was:

node node_modules/cross-env/bin/cross-env.js

I've fixed package.json file and made the path like this:

node_modules/cross-env/dist/bin/cross-env.js

And to not happen same issue again I've just set version of cross-env in dependencies to be strict.
