How "npm update" command works?-CodePudding

I got 3 dependencies on my project, when I run npm update it doesn't update the version of one dependency (axios). Here is my package.json file:

{
  ...
  "dependencies": {
    "axios": "^0.25.0",
    "date-fns": "^2.26.0",
    "lodash": "^4.17.15"
  }
}

When I enter the npm update or npm update --save command, this is the my actual result:

{
  ...
  "dependencies": {
    "axios": "^0.25.0",
    "date-fns": "^2.29.1",
    "lodash": "^4.17.21"
  }
}

As I can see, the axios package doesn't get updated. My expected result is to get the axios package at version 0.27.2 (latest at this day).

From docs

Caret Ranges ^1.2.3 ^0.2.5 ^0.0.4

Allows changes that do not modify the left-most non-zero element in the [major, minor, patch] tuple.

Since your axios dependency is defined as ^0.25.0, with its minor version 25 being the left-most non-zero element, it will allow update to 0.25.X, but not to 0.27.0.

Either change the dependency in your package.json, or let npm do it. This should install the newest version:

npm install axios@* --save

You can use npm update -d or npm update --save-dev to update developer dependencies. (Dependencies used in development) Using npm update only would ignore the dev dependencies.

You can now use the command npm install axios and it will automatically update axios in your package.json
