Function ensureLocalInstaller

ensureLocalInstaller(options: ILocalInstallerOpts): Promise<string>
Get the path for a locally-executable installer from cache, or as downloaded.

Note

Assumes url at least ends with the correct executable extension for this platform, but makes no other assumptions about the URL format: it might include GET params, was not built with constructor (but still has the same CLI), or has been renamed during a build process.
Parameters
- options: ILocalInstallerOpts
  Cache and download metadata for the installer.
Returns Promise<string>
The local path to the installer (with the correct extension).
Throws
If no executable path could be determined after all attempts.
Example
```
const localPath = await ensureLocalInstaller({
  url: "https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh",
  tool: "Miniconda3",
  version: "latest",
  arch: "x86_64",
});
```
