Lab 6.2 what is going wrong here?

andrewpartrickmiller

For lab 6.2 to install fastify with semver range starting at 2.0.0 and accepting all new minor and patch versions. I used the command

npm install -S fastify@2.00

Then I used

npm install -E rfdc@1.1.3

And then my package.json file revealed this:

{
  "name": "labs-2",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "node test"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "fastify": "^2.0.0",
    "rfdc": "1.1.3",
    "semver": "^7.1.3"
  }
}

when I run

node test.js

I get

assert.js:385
    throw err;
    ^

AssertionError [ERR_ASSERTION]: fastify should be greater than or equal to 2.0.0, while accepting all future MINOR and PATCH versions

  generatedMessage: false,
  code: 'ERR_ASSERTION',
  actual: false,
  expected: true,

}

Then when I read back through the reading, I read that ^2.0.0 means that fastify accepts any minor or patch versions that are equal to 2.0.0 or greater than 2.0.0. Which is what is listed in my package.json file.

I am having difficulty debugging this.

I guess I either have a misunderstanding or, something else is wrong.

Can someone please help me. Tell me what is going wrong, and what my misunderstanding is. Offer a solution or provide feedback however you'd like.

Thanks!

hey @andrewpartrickmiller

This is a (ironically) due to a breaking change in the semver package which was released in a minor instead of a major.

The following validate.js line:

assert(range === '>=2.0.0 <3.0.0', 'fastify should be greater than or equal to 2.0.0, while accepting all future MINOR and PATCH versions')

needs to be updated to

assert(range === '>=2.0.0 <3.0.0-0', 'fastify should be greater than or equal to 2.0.0, while accepting all future MINOR and PATCH versions')

This issue is no longer an issue. The test passes without any bugs

I downloaded the new labs and ran the code I described earlier in this post, with the typo corrected, and the test passed.
