npm install puppeteer showing permission denied er

Question

I'm unable to install puppeteer as a project dependency, and I've tried re-installing node. Anyone have an idea on how to fix this? Running Ubuntu 17.10 x64

sudo apt-get purge nodejs;
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -;
apt-get install -y nodejs;
sudo npm install -g n;
sudo n stable;

Node versions:

$ node -v
v9.4.0
$ npm -v
5.6.0

I try to install:

root@server:/var/www/html# npm install --save puppeteer

Error message:

> puppeteer@1.1.0 install /var/www/html/node_modules/puppeteer
> node install.js

Answer 1

Run this on your terminal:

sudo npm install -g puppeteer --unsafe-perm=true

Answer 2

EDIT 20th April 2019:

The easy solution suggested by lauraalvarezz1 is,

sudo npm install -g puppeteer --unsafe-perm=true

This is okay as long as you trust puppeteer and want it to install puppeteer globally.

However beware of using --unsafe-perm=true for permission related problems. Reasons are:

• Running unsafe-perm=true with sudo, as a non-root user, will give the script root access. This might be okay only if you trust the script and do not concern about security that much.
• You might need to use --no-sandbox in every script you run, because the chrome installed with this command might not run without this parameter. See this github issue.

---

You have installed npm with sudo. Thus anything you install globally will require sudo.

To install anything on var/www/html folder, either you have to own that folder,

sudo chown -R $USER /var/www/html

Or you can use nvm to manage npm. Technically it will use your home directory and your current user.

After installing nvm, you can install puppeteer globally with it,

npm i -g puppeteer

or you have to use sudo

sudo npm install --save puppeteer

However chromium will not be downloaded due to permission error, that's why you have to use ---unsafe-perm=true as stated before.

Best of luck!

Answer 3

Before you begin, make sure you have the most recent version of Node.js.

The Puppeteer Documentation states:

Note: Puppeteer requires at least Node v6.4.0, but the examples below use async/await which is only supported in Node v7.6.0 or greater.

You can check which version of Node.js you have using the following command:

node -v
# OR nodejs -v

If your version of Node.js is less then v7.6.0, you can completely uninstall your current version of Node.js.

Then, you can use complete the reinstallation using a PPA:

sudo apt update
curl -sL https://deb.nodesource.com/setup_8.x -o nodesource_setup.sh
sudo bash nodesource_setup.sh
sudo apt install nodejs
sudo apt install build-essential

You can check the new versions of Node.js and NPM installed on your system:

node -v
npm -v

Finally, you can install Puppeteer:

sudo npm install puppeteer --unsafe-perm=true --allow-root

Now you can run Puppeteer scripts using the node command:

node puppeteer-script.js
