Permission errors when trying to install Appium

If trying to install Appium in the classic way we get this error: Error: EACCES: permission denied as you can see in the following example:

mmagni@mmagni-lenovo:~$ sudo npm install -g appium
/usr/bin/appium -> /usr/lib/node_modules/appium/build/lib/main.js
/usr/bin/authorize-ios -> /usr/lib/node_modules/appium/node_modules/.bin/authorize-ios

The solution for this permission issue is to execute the same command but adding the following parameters:

mmagni@mmagni-lenovo:~$ sudo npm install -g appium --unsafe-perm=true --allow-root
/usr/bin/appium -> /usr/lib/node_modules/appium/build/lib/main.js
/usr/bin/authorize-ios -> /usr/lib/node_modules/appium/node_modules/.bin/authorize-ios

ERROR when trying to install the polymer-cli

If you try to install the polymer-cli:

$ sudo npm install -g polymer-cli

...and you get the following error:

Error: EACCES: permission denied, mkdir '/usr/lib/node_modules/polymer-cli/node_modules/wd/build'

You can solve it by running the command with the --unsafe-perm parameter:

$ sudo npm install -g polymer-cli --unsafe-perm

How to make an IFRAME responsive

This problem is solved wrapping the <iframe> with a <div>. The <div> has to have this CSS property:

.wrapper {
    -webkit-overflow-scrolling:touch;
}

<div class="wrapper">
