I had same problem and finally I understood that my node version is old. For example, you can install the current active LTS node version in Ubuntu by the following steps:
sudo apt-get update
curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
sudo apt-get install nodejs -y
Installation instructions for more versions and systems can be found in the following link:
https://github.com/nodesource/distributions/blob/master/README.md
Since i stumbled on the post via google:
Try using npm ci
it will be much than an npm install
.
From the manual:
In short, the main differences between using npm install and npm ci are:
- The project must have an existing package-lock.json or npm-shrinkwrap.json.
- If dependencies in the package lock do not match those in package.json, npm ci will exit with an error, instead of updating the package lock.
- npm ci can only install entire projects at a time: individual dependencies cannot be added with this command.
- If a node_modules is already present, it will be automatically removed before npm ci begins its install.
- It will never write to package.json or any of the package-locks: installs are essentially frozen.
You can bypass https using below commands:
npm config set strict-ssl false
or set the registry URL from https or http like below:
npm config set registry="http://registry.npmjs.org/"
However, Personally I believe bypassing https is not the real solution, but we can use it as a workaround.
npm ERR! node -v v0.8.0
npm ERR! npm -v 1.1.32
Update your node.js installation.The following commands should do it (from here):
sudo npm cache clean -f
sudo npm install -g n
sudo n stable
Edit: okay, if you really have a good reason to run an ancient version of the software, npm set ca null
will fix the issue. It happened, because built-in npm certificate has expired over the years.
If you're behind a corporate proxy, try this setting for npm with your company's proxy:
npm --https-proxy=http://proxy.company.com install express -g
Reinstall node, then update npm.
First I removed node
apt-get purge node
Then install node according to the distibution. Docs here .
Then
npm install npm@latest -g
