Ubuntu 17.10.1中离子错误

Question

friends I have the following problem to install ionic

I already have correctly installed nodejs and npm

then install ionic with sudo npm install -g ionic

when I try to consult the installed version, I find the following error:

ionic –v

[ERROR] Unable to find command: –v

    You may need to be in an Ionic project directory.

the strange thing is that I was able to install monaca and that works well, although monaca also uses ionic.

What I can do? Thanks

Answer 1

You are using a dash character (–) instead of the hyphen (-).

When I run your command ( ionic –v ) on Ubuntu 16.04 I get that same error, but then if I use the hyphen ( ionic -v ) I get the version out.
