pip install error - sys.stderr.write(f"ERROR: {exc}")

If you are getting the following error while installing a pip package, this solution should work for you.

sys.stderr.write(f"ERROR: {exc}")

Solution :

A) If you are installing a pip package with default python (2.7) and getting above error, run following command

curl https://bootstrap.pypa.io/2.7/get-pip.py --output get-pip.py
python get-pip.py

B) If you are installing a pip package with python3 and you are installing a package using pip3 command, run following command

curl https://bootstrap.pypa.io/3.5/get-pip.py --output get-pip.py
python3 get-pip.py

Change the python version in url, it depends on your system's python version.

C)  If you are installing a pip package in a virtual environment with python3.5,  run following command in your virtual environment

curl https://bootstrap.pypa.io/3.5/get-pip.py --output get-pip.py
python3 get-pip.py

phpLiteAdmin : No option visible to create / rename / delete database

If you have installed phpLiteAdmin in your Apache but you are unable to see the options to create / rename / delete database. Here is the solution for you.

Solution :

Your php code of  phpLiteAdmin does not have sufficient permission to show these options. You need to change the owner of the folder phpLiteAdmin.

If you have installed phpLiteAdmin in CentOS, your httpd user is apache, change the owner of the folder.

chown -R apache:apache phpLiteAdmin

If you have installed phpLiteAdmin in Ubuntu, your apache user is www-data, change the owner of the folder.

chown -R www-data:www-data phpLiteAdmin

If you have installed phpLiteAdmin in Lampp/Xampp, your apache user is daemon, change the owner of the folder.

chown -R daemon:daemon phpLiteAdmin

Now open again phpLiteAdmin in the browser. You should be able to see all options.

You can also try with 777 permission to the folder phpLiteAdmin but this is not a good practice to give full permissions to a folder of Document Root.
