When install the yeoman using the following command:
npm install -g yo
You might have the following error:
npm WARN deprecated cross-spawn-async@2.2.5: cross-spawn no longer requires a build toolchain, use it instead /root/.nvm/versions/node/v9.3.0/bin/yo -> /root/.nvm/versions/node/v9.3.0/lib/node_modules/yo/lib/cli.js /root/.nvm/versions/node/v9.3.0/bin/yo-complete -> /root/.nvm/versions/node/v9.3.0/lib/node_modules/yo/lib/completion/index.js > spawn-sync@1.0.15 postinstall /root/.nvm/versions/node/v9.3.0/lib/node_modules/yo/node_modules/spawn-sync > node postinstall sh: node: command not found npm ERR! file sh npm ERR! code ELIFECYCLE npm ERR! errno ENOENT npm ERR! syscall spawn npm ERR!

Try the following commands instead:
npm install -g try-thread-sleep npm install -g yo --ignore-scripts spawn-sync
Now try to type 'yo' to see if yeoman installed correctly, if you happened to have following error:
/root/.nvm/versions/node/v9.3.0/lib/node_modules/yo/node_modules/write-file-atomic/index.js:197 throw err ^ Error: EACCES: permission denied, open '/root/.config/insight-nodejs/insight-yo.json.3393582327' at Object.fs.openSync (fs.js:663:18) at Function.writeFileSync [as sync] (/root/.nvm/versions/node/v9.3.0/lib/node_modules/yo/node_modules/write-file-atomic/index.js:180:17) at Conf.set store [as store] (/root/.nvm/versions/node/v9.3.0/lib/node_modules/yo/node_modules/conf/index.js:142:19) at Conf.set (/root/.nvm/versions/node/v9.3.0/lib/node_modules/yo/node_modules/conf/index.js:64:14) at Insight.set optOut [as optOut] (/root/.nvm/versions/node/v9.3.0/lib/node_modules/yo/node_modules/insight/lib/index.js:56:15) at Object.<anonymous> (/root/.nvm/versions/node/v9.3.0/lib/node_modules/yo/lib/cli.js:198:18) at Module._compile (module.js:660:30) at Object.Module._extensions..js (module.js:671:10) at Module.load (module.js:573:32) at tryModuleLoad (module.js:513:12)
Try the following command to fix:
chmod g+rwx /root/.config/insight-nodejs/
If everything works fine, after type 'yo', you should see the following output:
