I am trying to install git-hours on Ubuntu 18.04 and I am getting an error:

/usr/local/lib/node_modules/git-hours/node_modules/promisify-node/utils/args.js:9
  var args = func.toString().match(/function\s.*?\(([^)]*)\)/)[1];
                                                              ^

I got things working on Ubuntu 16. Details posted here: #34

I get the same error trying to install on Windows 10. I don't think it's a nodegit issue because I installed nodegit separately and it worked.

Having same error on Mint 19, with npm 6.7.0.
nodegit is installed without problems

[fikrikarim]

I got exact problem when installing using node v10.16.0

It runs perfectly when I install using node v6.17.1

For anyone cannot install this tool using new version of node, it seems to be a problem with dependency nodegit.
I assign a specific latest version of nodegit in package.json, it works fine.

{
"devDependencies": {
    "git-hours": "^1.3.0",
    "nodegit": "^0.26.1"
  },
  "resolutions": {
    "nodegit": "^0.26.1"
  }
}

Should be a workaround (also fixed #43 ) before the author publish the new version

same error here on node 10 on chromebook's debian installation

apart from this tool's installation node works perfectly

Where is nodegit's package.json when installing -g globally?

[ndastur]

Still doesn't work using npm -g install ... Has it not been updated on npm?

[marekyggdrasil]

I worked it out #56 (comment)

After new release 1.5.0, npx git-hours works again! Tested with node 14, macOS. The node version is probably quite specific.
