Solve Error: node postinstall sh: node: command not found

 

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

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

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:
