Can't install Strongloop for Loopback v.3 on MacOS Catalina

I'm trying to learn about Loopback v3 (which is what they are using on a job site where I'm working), and I'm trying to follow their tutorials. One of the steps is to install Strongloop

npm i -g strongloop

but it keeps failing with these errors (among others):

static void SetMessageHandler(Isolate* isolate, ^ 5 warnings and 4 errors generated. make: *** [Release/obj.target/debugger/src/controller.o] Error 1 gyp ERR! build error gyp ERR! stack Error: make failed with exit code: 2 gyp ERR! stack at ChildProcess.onExit (/Users/me/.nvm/versions/node/v8.15.1/lib/node_modules/npm/node_modules/node-gyp/lib/build.js:262:23) gyp ERR! stack at emitTwo (events.js:126:13) gyp ERR! stack at ChildProcess.emit (events.js:214:7) gyp ERR! stack at Process.ChildProcess._handle.onexit (internal/child_process.js:198:12) gyp ERR!

This install attempt was Node v.8, but I tried it with Node v.12 first and that didn't work either.

I thought I'd try to go on and ignore the errors, but when I get to the ´datasource´section of the tutorial (https://loopback.io/doc/en/lb3/Defining-data-sources.html), it fails, which I suppose is because Strongloop was not correctly installed.

The new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor. Web server listening at: http://localhost:3000 Browse your REST API at http://localhost:3000/explorer events.js:187 throw er; // Unhandled 'error' event ^

Error: EISDIR: illegal operation on a directory, read Emitted 'error' event on DataSource instance at:

It's frustrating, as I don't know what to do to get Strongloop to install correctly. Any pointers much appreciated!

Solution

  • I'm trying to learn about Loopback v3 (which is what they are using on a job site where I'm working), and I'm trying to follow their tutorials. One of the steps is to install Strongloop

    StrongLoop CLI is not necessary for LoopBack development. It has been deprecated in favor of smaller & focused tools.

    You can find an up-to-date tutorial for starting with LoopBack here: https://loopback.io/lb3/getting-started

    The most important part is to install loopback-cli instead of strongloop:

    $ npm install -g loopback-cli

    IIRC, this package does not have any native dependencies requiring compilation, therefore you should not encounter any build errors from gyp.
