hi, even I am facing the same issue. can you help me with how to resolve this issue, please? I have been searching for an answer for the past 10 days I am not able to find any solution. please help me if anyone as any solution to this problem

Your error tells me that it was a problem building node-gl, one of the dependencies. The package could be pulling an outdated version. You could always clone the repo locally, change package.json and try doing a local npm install to see if it fixes it. Here's a little shell function I use to change versions quickly:

change_packagejs_version() {
  [ -f package.json ] || return 1
  local package="\"$1\""
  local new_version="\"$2\""
  local old_version="\"[^\"]*\""
  local ws="\s*"
  local search_expr="$package$ws:$ws$old_version"
  local replace_expr="$package: $new_version"
  sed -i package.json -e "s/$search_expr/$replace_expr/g"
}

Or a powershell version since that seems to be what you're using:

function Change-PackageJS-Version($package, $version, [Boolean]$print=$false) {
  If (!(Test-Path -Path package.json -PathType Leaf)) {
    return
  }
  set packageQuoted ('"' + $package + '"')
  set oldVersion '"[^"]*"'
  set newVersion ('"' + $version + '"')
  set ws '\s*'
  set searchExpr "$packageQuoted${ws}:$ws$oldVersion"
  set replaceExpr "${packageQuoted}: $newVersion" 
  set content ((Get-Content -Path package.json) -Replace "$searchExpr", "$replaceExpr")
  If ($Print -Eq $false) {   
    Set-Content -Path ./package.json -Value $content
  } Else {   
    Write-Output $content
  }   
}

Then you'd use them like so:

$ git clone https://github.com/transitive-bullshit/ffmpeg-concat
$ cd ffmpeg-concat
$ change_packagejs_version gl '*'
$ npm install -g
$ ffmpeg-concat --version

PS> git clone 'https://github.com/transitive-bullshit/ffmpeg-concat'
PS> cd ffmpeg-concat
PS> Change-PackageJS-Version gl '*'
PS> npm install -g
PS> ffmpeg-concat --version

Copy Pastable Versions

## Unix Shell ```bash git clone https://github.com/transitive-bullshit/ffmpeg-concat cd ffmpeg-concat change_packagejs_version() { [ -f package.json ] || return 1 local package="\"$1\"" local new_version="\"$2\"" local old_version="\"[^\"]*\"" local ws="\s*" local search_expr="$package$ws:$ws$old_version" local replace_expr="$package: $new_version" sed -i package.json -e "s/$search_expr/$replace_expr/g" } change_packagejs_version gl '*' npm install -g ffmpeg-concat --version ``` ## Powershell ```powershell git clone 'https://github.com/transitive-bullshit/ffmpeg-concat' cd ffmpeg-concat function Change-PackageJS-Version($package, $version, [Boolean]$print=$false) { If (!(Test-Path -Path package.json -PathType Leaf)) { return } set packageQuoted ('"' + $package + '"') set oldVersion '"[^"]*"' set newVersion ('"' + $version + '"') set ws '\s*' set searchExpr "$packageQuoted${ws}:$ws$oldVersion" set replaceExpr "${packageQuoted}: $newVersion" set content ((Get-Content -Path package.json) -Replace "$searchExpr", "$replaceExpr") If ($Print -Eq $false) { Set-Content -Path ./package.json -Value $content } Else { Write-Output $content } } Change-PackageJS-Version gl '*' npm install -g ffmpeg-concat --version ```

Honestly in my case I just updated all packages to latest and then fixed errors as they came, so I don't know what the minimum working versions are, but keep trying and I am sure you'll succeed, meow.

Did this solution work for you @EyalSinay I am facing an issue with Error: Cannot find module 'commander'

I tried install the commander, some other issues were coming up please help @fcard

[EyalSinay]

I didn't try because i already build my project with fluent-ffmp

[vin-the-dev]

I am still not able to install the package :(

[fcard]

@vineethvijayan314 I was working on updating the deps and changing the repo to the ES5 module system so I could send a PR or smth, but got distracted by other things.

But here's how I managed to fix it:

$ change_packagejs_version gl '*'
$ change_packagejs_version sharp '*'
$ npm audit fix # this takes a while, don't close/interrupt
$ npm install -g
$ ffmpeg-concat --version

There's still some bugs, which I don't know if they were there before the bit rot or not, but I managed to cat some files.
