Couldn't find the 'yo' binary. Make sure it's installed and in your $PATH. Could you tell me what the problem is?

问题

I'm using npm install -g yo gulp to install yeoman and this is the error I'm getting  
npm WARN deprecated cross-spawn-async@2.2.5: cross-spawn no longer requires a build toolchain, use it instead
C:\Usr\local\gulp -> C:\Usr\local\node_modules\gulp\bin\gulp.js

Like Xander Cage said.

I have uninstalled node.js -> procedure here
I have restarted my PC.
Then I installed again node.js

It work.

回答2:

Run the following command to see where npm puts global packages

npm config get prefix

You'll get output similar to this

/usr/local/Cellar/node/10.5.0_1

Copy the output or path and then using any code editor open your .bashrc or .zshrc file depending on the terminal you use and paste like so

export PATH="$PATH:"/usr/local/Cellar/node/10.5.0_1/bin/""

Then after saving run

source ~/.zshrc

回答3:

The above didn't work for me at all.

The following solved my problem: clean installed nodejs and followed steps by dv-here in thread: https://github.com/zkat/npx/issues/100 Note that my npm kept pointing to C:\usr...

I think I set the npm config set prefix= to something mistakenly due to which I was >getting the error. Here's how I fixed it:

Open CMD in "Administrator" mode.

npm cache clear --force

npm install

npm config set cache C:\Users\myname\AppData\Roaming\npm-cache

npm config set prefix C:\Users\myname\AppData\Roaming\npm

回答4:

I just ran into this issue on MacOS, and saw that all of my global npm binaries were symlinked into the /usr/local/bin directory, except for yo. I created a symlink using this command:

ln -s /usr/local/Cellar/node/12.10.0/bin/yo /usr/local/bin/yo

(Yours may vary)

And yo is now callable.

回答5:

I had same issue and I really didn't want uninstall nodejs as I have a lot of package installed. Tried also with the second answer and did not worked.

Then I found this ticked, that is been closed:

https://github.com/yeoman/yeoman/issues/1716

install with yarn command for me worked.

yarn global add yo

Seem then the installation went through with also binary installed.

Nevermind try to install it with npm getting same error, so looking for provide more infos
