I install generator, but can't find and use it.

[le0zh0u]

I use the command npm install -g generator-react-webpack to install react-webpack generator to yo. It works. After that, I run yo react-webpack , but it failed. And it shows:

Error react-webpack You don't seem to have a generator with the name react-webpack installed. You can see available generators with npm search yeoman-generator and then install them with npm install [name]. To see the 0 registered generators run yo with the '--help' option.

That means I didn't install any generator. But in root of npm's installation directory, I find 'generator-react-webpack' folder, and in that folder the command of yo react-webpack can work.

I use iterm and zsh in MacOS. And I try yo completion, it shows some options, I choose 'Zsh config file', but it shows even I use sudo : oh oh Error: EACCES: permission denied, open '/usr/local/lib/node_modules/.yo_npminstall/tabtab/1.3.2/tabtab/.completions/yo.zsh' at Error (native)

What should I do to fix it and use generator?

Hello @le0zh0u, could you run the following three commands and post their output? The comments show an example of what they output on my system. The paths may be completely different, but it is interesting if npm is looking in the correct directory for globally installed modules.

which yo
# /Users/sthzg/.nvm/versions/node/v6.2.2/bin/yo
which node
# /Users/sthzg/.nvm/versions/node/v6.2.2/bin/node
npm -g root
# /Users/sthzg/.nvm/versions/node/v6.2.2/lib/node_modules

[le0zh0u]

which yo
->  /usr/local/bin/yo
which node
->  /usr/local/bin/node
npm -g root
->  /usr/local/lib/node_modules

I think the paths are similar with yours. Should I config some file to make npm or yo know where is the correct directory for globally installed modules.

Thanks.

That's looking good. Does yo doctor output any problems?

yo doctor
# Running sanity checks on your system
#
# ✔ Global configuration file is valid
# ✔ NODE_PATH matches the npm root
# ✔ Node.js version
# ✔ No .bowerrc file in home directory
# ✔ No .yo-rc.json file in home directory
# ✔ npm version
#
# Everything looks all right!

doctor outputs everything is ok...

Yeoman Doctor
Running sanity checks on your system

✔ Global configuration file is valid
✔ NODE_PATH matches the npm root
✔ Node.js version
✔ No .bowerrc file in home directory
✔ No .yo-rc.json file in home directory
✔ npm version

Everything looks all right!

How can I let yo know where is the correct directory for globally installed modules?

I think maybe yo is looking in a wrong directory, so that it can't find any generator. Because I can run yo react-wepack under the generator-react-webpack directory.

Thanks.

Likely, yes, but that is what yo doctor should have checked 💭 . When you run the following, does it find generator-react-webpack installed in /usr/local/lib/node_modules?

npm -s ls -g --depth=0 |grep 'generator-'
# ├── generator-react-webpack -> /usr/local/lib/node_modules/generator-react-webpack

[le0zh0u]

npm -s ls -g --depth=0 |grep 'generator-'
├── generator-react-webpack@3.3.4

That outputs its name. And I do cd /usr/local/lib/node_modules, I find generator-react-webpack:

cd /usr/local/lib/node_modules
->  /usr/local/lib/node_modules
ls
->
bower                   generator-react-webpack supervisor
cnpm                    gulp                    webpack
express-generator       npm                     yo

@le0zh0u I might be tired and blind, but all paths seem to match so far. One more set of sanity checks:

If you run ls -l /usr/local/bin/yo, does this correctly link to /usr/local/lib/node_modules/yo/lib/cli.js? (also for completeness, could you paste your versions of yo, node and npm)?

ls -lha /Users/sthzg/.nvm/versions/node/v6.2.2/bin/yo
# ... /Users/sthzg/.nvm/versions/node/v6.2.2/bin/yo -> ../lib/node_modules/yo/lib/cli.js

@le0zh0u,

we had this problems once before. In the last case, it was a direct install that needed all global modules to be installed as root. The rights for the generator where then not picked up by "yo" correctly. Could you try installing nvm (https://github.com/creationix/nvm) and test with this? It will install node locally, which means you wont need admin rights to install globally.

@weblogixx ,

It works. I uninstall node on my laptop, and install nvm and node by your way. In the project directory, the command runs successfully. I don't know why. May it is a little bug.:)

Well, yesternight, I grant node_module folder to current user. And I don't need admin rights to install globally. But it didn't work.
