title: how to install node-pre-gyp binaries from local file
body: <p>I have some firewall restrictions and can't download some prebuild binaries for alpine, so i thinked that i can download locally the binary file and set the path somewhere. I did it with prebuild-install libraries like keytar, puting in .npmrc file</p>
  <pre><code>keytar_local_prebuilds=/tmp
  </code></pre>
  <p>There's a way to do the same with node-pre-gyp binaries? for example, bcrypt@5.0.1 (file bcrypt_lib-v5.0.1-napi-v3-linux-x64-musl.tar.gz)</p>
  <p>I have the files in a blob storage, so i can download them in the dockerfile.</p>
