TypeError: Cannot read property 'substring' of undefined

Freshly installed Eslint v1.5.1. When I run "eslint --init" for the first time, I get this.

Thanks for the issue! If you're reporting a bug, please be sure to include:

1. The version of ESLint you are using (run eslint -v)
2. What you did (the source code and ESLint configuration)
3. The actual ESLint output complete with numbers
4. What you expected to happen instead

Requesting a new rule? Please see Proposing a New Rule for instructions.

Are you using NPM 3 by any chance? Can you check your node_modules directory and find out what version of inquirer you are using?

[TheEradicated]

I'm using npm 2.14.3. Checked out the inquirer/package.json and this is the version, I think.

  "name": "inquirer",
  "version": "0.9.0",
  "description": "A collection of common interactive command line user interfaces.",
  "main": "lib/inquirer.js",

What is your OS?
There is a known issue on windows 10.

[TheEradicated]

I guess it's an issue. I'm running Windows 10 Enterprise LTSB.

I think this is a duplicate of #3395?

[ilyavolodin]

Doesn't look like it. It's crashing all together, and #3395 describes an issue where the arrow selection is not possible.

[TheEradicated]

Updated to v1.6.0, same thing (knew that it still isn't fixed). Also, I forgot the line on the top.

[ilyavolodin]

@TheEradicated I can't reproduce this locally on Windows 8 Professional or Windows 10 Professional. What version of Node are you using? Also, could you try blowing away node_modules directory under your eslint installation and running npm install again?

[TheEradicated]

@ilyavolodin I have Node.js 4.1.0. Deleted the node_modules folder under node_modules/eslint directory, ran npm install -g eslint and eslint --init after that. Same error.

[guilhermehn]

Same problem here on Win7 Home Premium SP1.

$ eslint -v
v1.6.0

$ node -v
v4.1.1

$ npm -v
2.14.4

The stack:

$ eslint --init

Removed eslint and installed again, but the problem persists.

[ilyavolodin]

OK, this is a known issue with inquirer and it's filed here: SBoudrias/Inquirer.js#272
It looks like it's a low priority issue for Inquirer and from some of the comments, it might not be fixable at all. Not really sure what we can do here.

[guilhermehn]

@ilyavolodin I just tested in Windows Command Prompt and it works fine. The problem happens only when using terminal emulators like mintyy that comes with git for Windows.

From Git for Windows FAQ:

Interactive and full-screen applications won't work at all

I think the issue can be closed, but a feedback about it would be nice, like showing a message if configInit.initializeConfig gets an error that the problem is possibly the terminal emulator.

[TheEradicated]

I'll use eslint (through SublimeLinter) for Sublime Text 3. Does this mean once I run eslint --init on Command Prompt, it will be good to go?

[ilyavolodin]

@TheEradicated Yes, if you use WIndows command prompt or powershell it should be fine. Bash for Git doesn't work (although it works for me personally for some reason).

i try with cmd(windows) and work fine the command 'bower init'
