how can i fix this? @grpc/grpc-js only works on Node ^8.13.0 || >=10.10.0

i just updated my node version on my machine and it works

There is node version issue so please update your node to install new node js from https://nodejs.org/en/ and after that, you can restart or close your terminal and reopen and then type that command

First of All You need to make sure to remove any conflicting versions of npm

sudo apt-get autoremove 

second use the following to install latest of npm

curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash - 

then

sudo apt-get install -y nodejs

that's for Debian distros, for another OS check this link: https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions-enterprise-linux-fedora-and-snap-packages

Alternatively, you can also use

sudo npm install -g npm@latest

or for version 8.13.0 particularly

 sudo npm install -g [email protected]
