copySync throw error when directory has unreachable symlinks

[lljxx1]

• Operating System:
  mac
• Node.js version:
  v12.14.0
• fs-extra version:
  8.1.0

error line:
https://github.com/jprichardson/node-fs-extra/blob/master/lib/copy-sync/copy-sync.js#L121

function copyDirItem stat.checkPathsSync should be use fs.lstatSync when options:dereference is false

[lljxx1]

quick fix
util/stat.js:getStatsSync

function getStatsSync (src, dest, opts = {}) {
  let srcStat, destStat
  const statSync = opts.dereference ? fs.statSync : fs.lstatSync
  if (nodeSupportsBigInt()) {
    srcStat = statSync(src, { bigint: true })
  } else {
    srcStat = statSync(src)
  }
  try {
    if (nodeSupportsBigInt()) {
      destStat = statSync(dest, { bigint: true })
    } else {
      destStat = statSync(dest)
    }
  } catch (err) {
    if (err.code === 'ENOENT') return { srcStat, destStat: null }
    throw err
  }


  return { srcStat, destStat }
}

I've encounted this issue as well.

As a quick workaround to anyone who also found this issue but doesn't want to patch node modules locally, https://www.npmjs.com/package/ncp seems to be a fine alternative for copy.

With that said, it seems the fix was just merged into v10, so hopefully this should be closed out soon! :)
