问题
To update the Vuetify component library in my project, I changed the version in package.json and ran the command npm install. Vuetify is now removed from the node_modules folder. How should I install it again? Why does npm install Vuetify not bring it back into node_modules?
回答1:
Run npm info vuetify to lookup for the list of versions that they have.
Install the specific version that you want with the following. I am using the latest vuetify v1.0.0-beta.6 as an example.
Example:
npm install --save vuetify@1.0.0-beta.6
Alternatively, if you prefer yarn
yarn add vuetify@1.0.0-beta.6
You can replace --save with -S flag instead.
yarn requires no flags to save them into dependencies.

to update vuetify version you must uninstall your old vuetify here is what i mean
uninstall it first
npm uninstall -S vuetify
then install it again
npm install -S vuetify
if you want to specify the version
npm install -S vuetify@1.0.0
for example.
-S or --save is for dependencies

In Mac or Ubuntu:
Just try the command npm install vuetify --save. It will update with latest one.
