I’m on Mac OS X and am using NVM installed via Homebrew. When I updated node with NPM, I started getting the error:
nvm is not compatible with the npm config "prefix" option
I tried many things to fix this. Here is what worked:
$ mkdir ~/.nvm $ brew update $ brew uninstall nvm
Note that during the uninstall of nvm, I was warned that two other npm versions still existed. Homebrew showed me how to delete them. You should also delete them if you get the same warning:
brew uninstall --force nvm
Then reinstall nvm and a node version of your choice:
$ brew install nvm $ brew install nvm 4.4.7 [or whatever version you want]
Also, I added the following two lines to ~/.bash_profile
export NVM_DIR="$HOME/.nvm" . "$(brew --prefix nvm)/nvm.sh"
Start a new terminal window or bash shell, and BOOM: problem fixed.
Let me know if this works for you or if you have any problems or better solutions…
