Runtime errors on Mac OSX

[alflanagan]

After installing version 1.34.0, I'm getting two error messages trying to run vmd. Version 1.33.0 worked fine, and after re-installing it worked normally again. Also, installing into the nvm environment for node 13.5.0 also worked.

$ nvm --version
0.35.1
$ npm --version
6.13.6
$ node --version
v10.18.1
$ vmd --version
1.34.0
$ uname -a

nvm was installed with Homebrew.

The errors received are:

Doing some prelim investigations and it appears that node@10 is an issue. My hunch is that it has something to do with node-gyp.

@alflanagan if you reinstall vmd in lts/erbium (node@12), it will work.

Investigation

• .travis.yml only tests node@7 and node@lts: This issue would probably have been caught if the matrix was all LTS version of node.

I have the same issue on node v10.14.1
