How to fix "zsh: command not found: vue"?

I installed @vue/cli on my mac, but whenever I type “vue”, my terminal says “zsh: command not found: vue” - How can I fix this problem? I searched similar issues and already spent half a day, but still not solved...

This is my environment:

• macOS Catalina version 10.15
• npm 6.4.1
• node v10.13.0

I changed $PATH by doing this:

echo 'export PATH="/usr/local/bin:$PATH"' >> ~/.zshrc

Now this is:

echo $PATH
/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin:/Library/Apple/bin:/usr/local/share/dotnet:/opt/X11/bin:~/.dotnet/tools:/Library/Frameworks/Mono.framework/Versions/Current/Commands

It looks like @vue/cli is installed, but I don't know why vue command is not found. Don't I have an admin privilege?

~ % npm install -g @vue/cli
/Users/ami/.npm_global/bin/vue -> /Users/ami/.npm_global/lib/node_modules/@vue/cli/bin/vue.js
+ @vue/cli@4.0.5

~ % node -v
v10.13.0
~ % npm -v
6.4.1
~ % vue -v    
zsh: command not found: vue
~ % vue create new-project
zsh: command not found: vue

I'm following Vue CLI's instruction, so the result is supposed to be creating a new vue project. https://cli.vuejs.org

SOLVED Thank you for your advice! I tried ~ % export PATH=~/.npm_global/bin:$PATH and my path became:

~ % echo $PATH
/Users/ami/.npm_global/bin
:/usr/local/bin
:~/.npm_global/bin
:/usr/local/bin
:~/.npm_global/bin
:/usr/local/bin
:/usr/bin
:/bin
:/usr/sbin
:/sbin
:/Library/Apple/usr/bin
:/Library/Apple/bin
:/usr/local/share/dotnet
:/opt/X11/bin:~/.dotnet/tools
:/Library/Frameworks/Mono.framework/Versions/Current/Commands

And try again:

~ % vue --version
@vue/cli 4.0.5

Worked!
