"Error: ENOENT: no such file or directory, open" when trying parcel serve --log-level 5

🐛 bug report

When I try to enable log level 5 on the parcel dev server parcel serve I get an error.

Error: ENOENT: no such file or directory, open '/Users/rosensama/projects/newproject/parcel-debug-12/10/2018@11:32:21 PM.log'

🎛 Configuration (.babelrc, package.json, cli command)

No .bablerc used. This is an Elm project (thanks for the built-in plugin!) so package.json is minimal.

    "dependencies": {},
    "scripts": {
        "build": "parcel build src/index.html",
        "serve": "parcel serve src/index.html --https --cert server/ssl.cert --key server/ssl.key --log-level 5"
    },
    "devDependencies": {
        "node-elm-compiler": "^5.0.1",
        "semantic-ui": "^2.4.2"
    }

The command is parcel serve src/index.html --https --cert server/ssl.cert --key server/ssl.key --log-level 5

🤔 Expected Behavior

It should create a log file and operate as normal.

💁 Possible Solution

Check if directories exist and create them if needed? If I manually create parcel-debug-12/ and parcel-debug-12/10/ in ~/projects/newproject, it works.

The failed path in is my home directory and parcel is being run as me, combine that with how creating the directories helps and I'm 99% this is not a permissions problem.

It's a tangent, but I suggest removing the spaces and special characters that require escaping at a shell prompt from the file name. Look at the log file name in .npm/_logs, for example.

🔦 Context

I'm troubleshooting my application and wanted to see if the most verbose level included any helpful information, so was trying the highest log level.

Not sure why this happens as cwd should normally exist?

[rosensama]

I don't think the missing directories would normally exist, but I don't know how cwd() resolved them.

In my example /Users/rosensama/projects/newproject/ is where package.json is found. I needed to create two directories that I wouldn't expect to normally exist as they involve the month and date and are parcel specific.

/Users/rosensama/projects/newproject/
    parcel-debug-12/  
        10/                                 <-- worked once created

Dumping the output of cwd() and the log file path, it seems to be a mismatch between the logfile path and the path createWriteStream is pointed to. I dumped both after line 75 and:

cwd: /Users/rosensama/projects/mendoza
this.logFile.path: '/Users/rosensama/projects/mendoza/parcel-debug-12/11/2018@8:21:26 PM.log'

Maybe just pass this.logFile.path to createWriteStream or set this.logFile.path to join(cwd, filename).

My tangential request was a dupe of #2288 (already merged).

[DeMoorJasper]

@rosensama ow now I see. The log file uses toisostring, which can include a / which makes it a directory instead of part of the filename. Probably best if we replace / and\ with a -

[rosensama]

To be clear toISOString is not used in the version I'm running (the current release, I think) but I do see that #2288 moved to that to make for friendlier names. My version is using toLocaleTimeString.

I'm pretty sure ISO time strings do not include slashes (unless you are doing intervals).

[DeMoorJasper]

@rosensama you're right I mixed those up. Than this issue should probably be closed as it's already fixed.

I'm getting close to the same error:
