this might be https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-p... nodejs's website told me to use npx instead of npm. not sure how to use npx. 0351. i can run these binaries with `npx mango-admin --help` for example, but it redownloads the package every run. npx's --help says to check man npx, ,but `man npx` doesn't work on my system. i'm using dpkg to see where my npx came from. it's 0357 the man pages are installed into node_modules; i can load them manually. 0357. 0402. i looked around a bit. installed npm-run globally per a comment in https://stackoverflow.com/questions/49302438/why-does-npx-install-webpack-ev... . didn't seem to help. 0404 i fitzed around a bit and ended up doing an `chown -R` on `~/.npm` which seems to be making `npm install -g` work now. both mango-admin and git-remote-mango are installing with npm without issue.
