Permission issues when install ijavascript

[dclong]

Running sudo npm install -g ijavascript gives me the following error message.

prebuild-install WARN install EACCES: permission denied, access '/home/chdu/.npm'

fs.js:115
    throw err;
    ^

@dclong If you really need a sudo install, npm version 5 and above require the flag --unsafe-perm, like this:

sudo npm install -g --unsafe-perm ijavascript
