The Linux operating system uses Python to implement the visualization function of the task manager

1. Python installation

1. Create a folder.

mkdir python 

Enter the folder and decompress it:

tar zxvf Python-3.6.5.tar

Enter the Python-3.6.5 folder and enter:

./configure

Next, a lot of processes will appear, and finally you will be prompted to run a command. Just enter the command as prompted.

Enter the make command (if the prompt does not exist, just use apt install make to install it) and wait.

make && make install #compile and install

Just continue to wait for the installation to complete.

At this time, we cd to the root directory to check our own python version (because python 2.7 cannot implement the library functions of versions above 3.0)

python -V

I found that it is still 2.7. What is the reason?

This is because the pyton3.6 version you installed has not been modified to the system default version

At this time, you need to delete the python related files in the /usr/bin/ directory

cd /usr/bin
ls -al *python* #View the version pointed to by the existing soft link rm python #Delete the old soft link ln -s python3.6 python #Create a new soft link

Then check the current version, it is the normal version.

2. Install pycharm

After decompression, enter the pycharm directory:

cd pycharm-community-2019.2.5/bin
bash pycharm.sh #Execute the program

But it is troublesome to enter the directory every time you open it, so we create a "shortcut":

3. Install third-party libraries

When the system installs Python 3.6 by default, its built-in pip is also pip 3 (if there is no pip, use the apt install pip3 command to install it). Because errors always occur when using pip for installation, it is recommended to download the installation package from the official website and install it yourself.

Here are some examples:

After downloading the file, go directly to this directory:

Just install it!

pip install PyQt... #done
