npm install -g ios-deploy 失败问题的解决方法 转载

当使用Cordova或ionic命令行时，

npm install -g iOS-deploy

或sudo npm install -g ios-deploy 都报错，

如：

npm WARN lifecycle ios-deploy@1.8.5~preinstall: cannot run in wd %s %s
(wd=%s) ios-deploy@1.8.5 ./src/scripts/check_reqs.js &&
xcodebuild /usr/local/lib/node_modules/.staging/ios-deploy-298c9491

npm ERR! Darwin 15.3.0

npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "install" "-g" "ios-deploy"

npm ERR! code ENOENT

npm ERR! errno -2

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 most likely not a problem with npm itself

npm ERR! enoent and is related to npm not being able to find a file.

npm ERR! enoent

解决问题方法在 https://github.com/phonegap/ios-deploy/issues/188 可以找到，其实就是：

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

这次倒给出了提示：
