NPM install-g Ios-deploy The solution to the failure problem reproduced

When using Cordova or ionic command lines,

NPM install-g Ios-deploy

or sudo npm install-g ios-deploy all error,

Such as:

NPM WARN Lifecycle [email protected]~preinstall:cannot run in WD%s%s (wd=%s) [email protected]./src/scripts/check_reqs . js && xcodebuild/usr/local/lib/node_modules/.staging/ios-deploy-298c9491

NPM err! Enoent enoent:no such file or directory, chmod '/usr/local/lib/node_modules/ios-deploy/build/release/ios-deploy '
NPM err! Enoent This is the most likely not a problem with NPM itself
NPM err! Enoent and is related to NPM, being able to find a file.
NPM err! Enoent

The problem solving method can be found in https://github.com/phonegap/ios-deploy/issues/188, which is actually:

sudo npm install-g ios-deploy--unsafe-perm=true

This time it gives a hint:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
