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:

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!

from: can’t read /var/mail/ in Python scripts

If you add a Python file to your PATH, maybe you will see this error: from: can’t read /var/mail/$First_Library_Name This happend, because you need to be explicit with application you want to run your script. To fix it, just add in the first line of your script the following line: #! /usr/bin/python Enjoy it!

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

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

If you try to run a mininet script like this , maybe you will get this problem if you are under Ubuntu. Exception: Could not find a default OpenFlow controller This is trigger because your system don’t find a default controller . To enable it just add the first line and add the controller argument to net variable like the second line: from mininet.node import OVSController net = Mininet(topo=topo,host=CPULimitedHost, link=TCLink,controller = OVSController) Now, you will get the following error: c0 Cannot find required executable ovs-controller. 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. You need to be sure that you has it. sudo apt-get install openvswitch-testcontroller sudo cp /usr/bin/ovs-testcontroller /usr/bin/ovs-controller If you run it again, you should kill ovs-testcontroller first to avoid this: Exception: Please shut d

for python 2.X try

Code: Select all

$ sudo apt-get install python-pip libglib2.0-dev
$ sudo pip install bluepy

to install dependencies and bluepy

if your intending to use it with python3.x use pip3 to install..

The problem is pip (or actually an elderly version of the ‘requests’ package)

I would reinstall pip
On Raspbian Stretch:

Code: Select all

sudo apt remove python-pip
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
sudo python get-pip.py

Теперь я не знаю, что еще я должен попробовать. Спасибо

См. эту проблему с github:

I guess that’s why I’m using the dorm Internet. I think there’s restriction.

@buran I have now installed the internet from my phone. Now I have this problem.

where your code comes from? what is bluescan? i.e. if you create the code you should now what package module it is. is it installed? is it the one part of bluepy?
Obviously it’s this one https://github.com/magitnus/bluescan/blo…blescan.py
and it is based on https://github.com/adamf/BLE/blob/master/ble-scanner.py

sorry, i didn’t realise it’s your code that print that error accessing bluetooth device… and I didn’t have any idea why you cannot access the device.
remove the try/except block.
by using blank except you shadow any exception message that will tell what’s wrong
you should always use specific error that you can catch

EDIT: I see — scan(sock) should be scan_sock(sock)
