in the web3 version 1.x docs: https://web3js.readthedocs.io/en/1.0/getting-started.html it says to install web 3 using

> npm install web3

but this installs version 0.2x.00.

so what should I do?

To view all versions of an npm package, enter npm view web3 versions. It'll list an array of all available version. To install a specific one, type npm install web3@versionNumber.

run 

sudo npm install -g web3@1.0

which will list all available versions: Valid install targets:
