git clone https://github.com/direnv/direnv
cd direnv
sudo make install

I tried to install direnv with this procedure,

When you run sudo make install,

cloud9user: ~/environment/myapp/direnv (master) $sudo make install
Could not generate man page because go-md2man is missing. Run: go get -u github.com/cpuguy83/go-md2man
make: *** [man/direnv.1] Error 1

I get an error like this.

As written here,

go get -u github.com/cpuguy83/go-md2man

And run

I ran sudo make install again
I get the same error again.

I suspect the corrective action for my error is wrong.

I would appreciate it if anyone could tell me how to solve it. ..
