How to fix a pip3 failed installation

In my case, I was trying to install bluepy from pip3 with the following command:

pip3 install bluepy

But an error appears:

fatal error: glib.h: No such file or directory\n #include <glib.h>\n                  ^\ncompilation terminated.\nMakefile:28: recipe for target 'bluepy-helper' failed\nmake: *** [bluepy-helper] Error 1\nmake: Leaving directory '/tmp/pip-build-djwz1adc/bluepy/bluepy'\n"

 ----------------------------------------
Cleaning up...
Command /usr/bin/python3 -c "import setuptools, tokenize;__file__='/tmp/pip-build-djwz1adc/bluepy/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-p2v5kjik-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /tmp/pip-build-djwz1adc/bluepy
Storing debug log for failure in /root/.pip/pip.log

Usually, we see the outpu after Cleaning up..., but it's very important see before it. As you can see, it says glib.h is not found. To solve it, we need to install it.

 apt-get install libglib2.0-dev

If you don't see an specific fatal error like this case, install python developer:

 apt-get install python3-dev

Enjoy it!

Exception: Could not find a default OpenFlow controller in Mininet

If you try to run a mininet script like this  , maybe you will get this problem if you are under Ubuntu.

Please make sure that it is installed and available in your $PATH: (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin) ovs-controller is a legacy name.

How to fix Android when developer options are not available for this user

Image
I have an Android One with Oreo version and suddenly my Android rebooted and after that it started to behave strangely: 1) Notification section doesn't work. I can't see notifications from my apps and the arrow and the screw icon to settings access don't work. 2) As I can't access to the notification area, I can't enable Use USB to Transfer Files to access to my phone memory. 3) I can't access to developer mode (I before active it with a lot of taps over Build number). Clicking on developer options just shows developer options are not available to this user. 4) I can't update or install the apps on google play. They freeze on Download pending... message 5) Home and Switch buttons don't work. They light up and vibrate when I tap them but they do nothing. This issue is apparently related to a deconfiguration of user accounts. To fix it, you need re-setup the users. As you can't access to the user manager (you are in guest mode
