Angular CLI 12.2.0 fails "ng add" with "Command aborted." without confirmation prompt #21512

daiplusplus · 2021-08-05T16:58:45Z

🐞 Bug report

Command (mark with an `x`)

Is this a regression?

Did this behavior use to work in the previous version?

Yes

Yes, the previous version in which this bug was not present was: ....

v11 (I haven't used other v12.x versions)

Description and 🔬 Minimal Reproduction

Running ng add always fails with "Command abort.ed" unless I add --skip-confirmation.
Additionally, there is no difference in output with or without --verbose.

For example:

$ cd ~

$ mkdir test

$ cd test

$ npm install -g @angular/cli
# etc

$ ng add @angular-eslint/schematics@12.2.0

Anything else relevant?

Windows 10 x64
Using git-bash as my shell in a mintty window.

I fiddled with add-impl.js to see why it wasn't prompting and I think the problem is add-impl.js has if( !tty_1.isTTY ) { but prompt.js has if (!tty_1.isTTY()) {, so is isTTY a function or a getter-property?

The text was updated successfully, but these errors were encountered:

@alan-agius4 The isTTY() change you just made doesn't work for me because when I run it with my additions below, I get typeof process.stdout.isTTY is 'undefined', even though I'm running ng add directly from a terminal window without any redirection (so isTTY should be true, right?)

From Node's docs:

https://nodejs.org/api/tty.html#tty_tty

$ node -p -e "Boolean(process.stdout.isTTY)"
true
$ node -p -e "Boolean(process.stdout.isTTY)" | cat
false

When I run the same commands locally I get the same results:

Screenshot proof:

This the code I added in add-impl.js right before the if (!options.skipConfirmation) { line:

    this.logger.error( options.skipConfirmation ? 'options.skipConfirmation == true' : 'options.skipConfirmation == false' );
    this.logger.error( typeof tty_1.isTTY );
    this.logger.error( 'tty_1.isTTY ==' + ( tty_1.isTTY ? 'isTTY' : 'is NOT TTY' ) );
    this.logger.error( 'tty_1.isTTY() ==' + ( tty_1.isTTY() ? 'isTTY' : 'is NOT TTY' ) );
    this.logger.error( 'process.stdout.isTTY type == ' + ( typeof process.stdout.isTTY ) );
    this.logger.error( 'process.stdout.isTTY == ' + ( process.stdout.isTTY ) );

    if (!options.skipConfirmation) {

Gives me this output:

options.skipConfirmation == false
function
tty_1.isTTY ==isTTY
tty_1.isTTY() ==is NOT TTY
process.stdout.isTTY type == undefined
process.stdout.isTTY == undefined

So why is process.stdout.isTTY undefined when in tty.js but not normally?

daiplusplus · 2021-08-05T17:43:35Z

After some more digging, when I try to get stdout.isTTY from anywhere before add-impl.js runs, such as in init.js or even in ng itself, I get errors.

Here's my code (in C:\Users\me\AppData\Roaming\npm\node_modules\@angular\cli\bin\ng):

process.stdout.write("------------------------\n");
console.trace( "ng: Stack trace\n" );
process.stderr.write("Writing to stderr\n");
process.stdout.write("Writing to stdout\n");
process.stdout.write("typeof stdout.isTTY === '" + typeof process.stdout.isTTY + "'\n");
try { process.stdout.write( process.stdout.isTTY ); }
catch( err ) { process.stdout.write( "Couldn't get isTTY: " + err ); }
process.stdout.write("\n");
process.stdout.write("------------------------\n");

Gives me this output:

$ ng add @angular-eslint/schematics
------------------------

Couldn't get isTTY: TypeError [ERR_INVALID_ARG_TYPE]: The "chunk" argument must be of type string or an instance of Buffer or Uint8Array. Received undefined

And yet, running node -p -e "process.stdout.isTTY" directly still works just fine:

$ node -p -e "process.stdout.isTTY"
true

any ideas?

That is interesting, not sure how to debug this from my end since I don’t have a Windows machine.

In the past we did see a number of TTY issues with GitBash and typically they were never actionable form our end. In most cases these were address by Node.JS as far as I can tell.

daiplusplus · 2021-08-05T17:58:19Z

@alan-agius4 I just realised that the error is because stdout.write does not accept a bool parameter - but it's also reporting isTTY is undefined, so I've got my errors crossed - but it's still broken. I'll update this comment in a short while.

daiplusplus · 2021-08-05T18:09:51Z

cmd.exe, when running node.exe myscript.js has process.stdout.isTTY === true.
cmd.exe, when running ng add foobar to indirectly run my hacked ng.js script has process.stdout.isTTY === true.
bash , when running node.exe myscript.js has process.stdout.isTTY === true.
bash, when running ng add foobar to indirectly run my hacked ng.js script has process.stdout.isTTY === undefined.

So that's narrowing it down...

UPDATE: So apparently the culprit is the ng bash script (at C:\Users\me\AppData\Roaming\npm\ng) which runs node via exec, and apparently doing exec node is what causes process.stdout.isTTY to be undefined

daiplusplus · 2021-08-05T18:34:42Z

@alan-agius4

Correct, running node node_modules/@angular/cli/lib/init.js add foobar directly from git-bash has stdout.isTTY === true.

Running node node_modules/@angular/cli/lib/init.js add @angular-eslint/schematics@12.2.0 succeeds and it asks me for a confirmation prompt.

Can't we replace exec node with just node in the ng bash script, perhaps?

Update: I changed my ng bash script from this:

#!/bin/sh
basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")

case `uname` in
    *CYGWIN*|*MINGW*|*MSYS*) basedir=`cygpath -w "$basedir"`;;
esac

if [ -x "$basedir/node" ]; then
  exec "$basedir/node"  "$basedir/node_modules/@angular/cli/bin/ng" "$@"
else 
  exec node  "$basedir/node_modules/@angular/cli/bin/ng" "$@"
fi

to

#!/bin/sh
basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")

case `uname` in
    *CYGWIN*|*MINGW*|*MSYS*) basedir=`cygpath -w "$basedir"`;;
esac

if [ -x "$basedir/node" ]; then
  node  "$basedir/node_modules/@angular/cli/bin/ng" "$@"
else 
  node  "$basedir/node_modules/@angular/cli/bin/ng" "$@"
fi

And yet process.stdout.isTTY === undefined still, curious...

Perhaps as an immediate workaround, add a warning output to init.js if typeof isTTY !== 'boolean' ?

daiplusplus · 2021-08-05T19:06:25Z

I've raised a bug with NodeJS here: nodejs/node#39673

UPDATE: So while the root cause is that isTTY is undefined in NodeJS when bash-on-Windows indirectly, which is another example of "the winpty problem" described here: https://stackoverflow.com/questions/45890339/stdout-is-not-a-tty-using-bash-for-node-tape-tap-spec

As a quality-of-life improvement, I suggest the ng shell-script print a warning if winpty isn't available, and if so, run the child node process via winpty, thoughts?

alan-agius4 · 2021-08-05T19:53:27Z

@Jehoel, the mentioned shell script is actually generated by NPM and not Angular.
Hence we have no controller of its contents.
