Is it possible to upgrade node right in place, instead of manually installing the latest stable version?
I have installed node.js version 5.0 with nvm, but now I want to update it to 5.4. I'm trying to avoid having to manually reinstall all of my global packages (e.g. by running npm install -g grunt-cli bower yo yoman-angular-generator blabla blablablabla...).
This may work:
nvm install NEW_VERSION --reinstall-packages-from=OLD_VERSION
For example:
nvm install 6.7 --reinstall-packages-from=6.4
then, if you want, you can delete your previous version with:
nvm uninstall OLD_VERSION
Where, in your case, NEW_VERSION = 5.4 OLD_VERSION = 5.0
Alternatively, try:
nvm install stable
You can more simply run one of the following commands:
Latest version: nvm install node --reinstall-packages-from=node
Stable (LTS) version: nvm install lts/* --reinstall-packages-from=node
This will install the appropriate version and reinstall all packages from the currently used node version. This saves you from manually handling the specific versions.
Edit - added command for installing LTS version according to @m4js7er comment.
if you have 4.2 and want to install 5.0.0 then
nvm install v5.0.0 --reinstall-packages-from=4.2
the answer of gabrielperales is right except that he missed the "=" sign at the end. if you don't put the "=" sign then new node version will be installed but the packages won't be installed.
