I'm opening this issue because:

• npm is crashing.
• npm is producing an incorrect install.
• npm is doing something I don't understand.
• npm is producing incorrect or undesirable behavior.
• Other (see below for feature requests):

What's the feature?

Unlike other packages such as Git, if you mistype a command, there is no suggestion of similar commands you might have meant.

What problem is the feature intended to solve?

Suppose the user has a script lint:src and tries these commands:

• src:tslint ❌
• src:lint ❌
• tslint:src ❌
• lint:srv❌
• lint:src ✔

None of the ❌s give an indication of other commands being similar.

C:\Code\Project (master -> origin)
λ npm run src:lint
npm ERR! missing script: src:lint

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\jogol\AppData\Roaming\npm-cache\_logs\2018-05-24T10_40_07_124Z-debug.log

Easy mode: tslint:src❌ and lint:srv❌ have low edit distances to lint:src✔. Solution proposal: if the command isn't found, give the first 1-3 commands with a low edit distance out of the union of (built in commands) & (package.json commands).

Hard mode: src:lint❌ flips lint:src✔ around the :. How common is the group:specific pattern? It could be useful to also check reverses of the scripts and consider them in the edit distances.

Bonus points if someone puts the 📎 emoji and "I see you're trying to X" phrasing in there on terminals that can support it!

C:\Code\Project (master -> origin)
λ npm run src:lint
npm ERR! missing script: src:lint

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\jogol\AppData\Roaming\npm-cache\_logs\2018-05-24T10_40_07_124Z-debug.log

📎 I see you're trying to run a command! Did you mean to type:
    npm run lint:src

Is the absence of this feature blocking you or your team? If so, how?

Not a blocker. However, for devs on my team who are either new to programming in general or come from the non-JS areas, this is an infrequent complaint.

Is this feature similar to an existing feature in another tool?

Git:

λ git pust
git: 'pust' is not a git command. See 'git --help'.

The most similar command is
        push

Is this a feature you're prepared to implement, with support from the npm CLI team?

Heck yes! 🤘
