title: Specifing semver operator for npm install --save
body: <p>By default <code>npm install --save</code> uses <code>^</code> as the semver operator. I know that this default can be changed using setting the <a href="https://docs.npmjs.com/misc/config#save-prefix" rel="nofollow"><code>save-prefix</code></a> config. But since I want to specify <code>~</code> for dependencies and <code>^</code> for devDependencies, I don't want to change the config. Is there a way to specify the <code>~</code> operator with the <code>--save</code> command?</p>
