Answer 1

Seems, this issue due to update

https://www.npmjs.com/package/@types/d3-dsv/v/0.4.4?activeTab=versions

I have this problem too.

Try to fix lib version to 1.0.31 in your package.json

"devDependencies": {
    "@types/d3-dsv": "1.0.31"
}

Answer 2

It looks like the issue may have been the "latest" tag for @types/d3-dsv switching from the 1.0.x versions (that contain exports for DSVRowString etc.) to 0.4.x (that don't), as described in this GitHub issue. Hopefully there will be a response to the issue that will remove the need for the version pinning.

So, at least for me, it was enough to pin to the latest 1.x.x version, and not necessary to lock to previous version (as suggested in another answer), e.g:

"devDependencies": {
  "@types/d3-dsv": "^1.0.32"
}

Update (28/05/18):

Looks like the issue is temporarily resolved due to the release of version 1.0.33 causing the "latest" tag to point back to the 1.0.x branch. However, as per a comment on the GitHub issue this isn't necessarily a permanent fix, and another release of the 0.4.x code could cause the same issue.

Answer 3

It seems to be resolved, I just built my application without any problems any without the devDependencies for d3-dsv.

There is was an update to the package a couple of hours ago: https://www.npmjs.com/package/@types/d3-dsv/v/0.4.4?activeTab=versions
