`noSymbolVersion` doesn't have a value if `parsedSpec.version` doesn't have
a `^` or `~`. I'd fix that by giving `noSymbolVersion` a default value of
`parsedSpec.version`. Like:
```
var noSymbolVersion = parsedSpec.version
```
So the purpose of this code is to replace the plugin dependency version in
`package.json` if the user passes in a specific one that doesn't satisfy what
is already in `package.json`.
I believe `parsedSpec.version` can be:
* a version number (possibly with ^ or ~)
* a url
* a local path
I think semver.satisfies would fail if `parsedSpec.version` was url or
path.
Maybe we do checks similar to line 428 to see if `parsedSpec.version` is a
URL or directory. If it is, don't do th satisfies check, instead do a
equivalence check (pkgJson.dependencies[parsedSpec.package] ===
parsedSpec.version)
We also don't check if fetchOptions.save is true. We don't want to write to
package.json unless that is true.
