@MatchLemon what version of Node are you running? Did you try lts/carbon v8.11.x? How did you install this version of TileMill?

@MatchLemon what version of Node are you running? Did you try lts/carbon v8.11.x? How did you install this version of TileMill?

my node is v8.15.0. my TileMill is master branch, run npm install & npm start

I just attempted a fresh install on a VM instance of Ubuntu 18.04.2 LTS, with Node v8.15.1 and npm v6.4.1 and it installed and ran as expected.

To install, I followed the Quick Install directions on the README: git clone https://github.com/tilemill-project/tilemill.git cd tilemill npm install npm start

Don't use the older Ubuntu installation instructions, those are for pre v1.0.0, before the latest upgrade.

@MatchLemon I get the same error if I didn't remove previously installed node_modules and do a clean install: From your local tilemill directory: rm -rf node_modules npm install

Can you please retest and report back?

I meet this problem too.But I don't want to remove the node_modules,I wiil install in a offline machine，so I can't download the node packages online. @csytsma Is there another way to solve my problem？

@younghappy, removing the node_modules directory in the project folder is typically a requirement when updating a node project package. You don't need to remove your global node_modules directory, just your ../tilemill/node_modules directory. You'll need to do this every time you upgrade TileMill, then run npm install again, to repopulate it with any new dependencies.
