I ran sudo npm install -g generator-flask and it was saved. I was able to confirm by running npm list-g.
I then run yo flask. Thinking that this was going to work, I instead get an error message:
Error flask You don't seem to have a generator with the name flask installed. You can see available generators with npm search yeoman-generator and then install them with npm install [name]. To see the 22 registered generators run yo with the `--help` option.
I do as it tells me by running yo --help and discover that the flask generator is not there.
I try this with sudo npm install -g generator-angular-flask and the problem is recreated with Angular Flask. I'm assuming this is going to happen for all the generators which is why I've titled it as Yeoman not recognizing new npm installs.
Does anyone know why this has happened?
回答1:
A workaround, but does solve the problem:
npm link generator-angular-flask
(as does just installing the module locally)
回答2:
Usually it is a $NODE_PATH issue, but rather then guessing, run:
yo doctor
and follow the instructions!
回答3:
Node path is the issue. To setup path:
export NODE_PATH=$HOME/.node/lib/node_modules/
In my case node is in HOME directory.

I was having a similar issue. Basically Yeoman was showing No installed generators, even if I fired up yeoman and installed the generator again still no luck to run it.
I typed yo doctor and did the changes it recommends, but still no luck...
I then ran
export NODE_PATH=$HOME/.node/lib/node_modules/
Then I fired up Yeoman and still no luck.
I then decide run yo doctor again and voila! New errors. I then saw the final recommendation by the yo doctor so I decide to run it:
export NODE_PATH=$NODE_PATH:/Users/slickstyles/.npm-global/lib/node_modules
After I type yo and guess what I see? All my installed yeoman generators showing and working marvelously.

You can use:
yo doctor
and you will not something like:
npm root value is not in your NODE_PATH [Info] NODE_PATH = /home/action/.node/lib/node_modules/ npm root = /home/action/.parts/lib/node_modules [Fix] Append the npm root value to your NODE_PATH variable Add this line to your .bashrc export NODE_PATH=$NODE_PATH:/home/action/.parts/lib/node_modules Or run this command echo "export NODE_PATH=$NODE_PATH:/home/action/.parts/lib/node_modules" >> ~/.bashrc && source ~/.bashrc
and try again:
npm install -g generator-webapp

Check if you have NODE_PATH set. To set it open a terminal and type (assuming you have node under /opt/node/ and use bash shell)
echo "export NODE_PATH=/opt/node:/opt/node/lib/node_modules" >> ~/.bashrc && . ~/.bashrc
Once done, run yo doctor. If all is ok, run yo to see your installed generators.
