ModuleNotFoundError: No module named 'distutils.cmd' // 🔴 not good


🟠 If that failed, then try this:

  • 1) Install pip using apt (if available)

  • If apt is giving you trouble, you might try installing pip via the Ubuntu package manager directly, although this method may not always yield the most recent version of pip: sudo apt install python3-pip

// OUTPUT
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package python3-pip is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'python3-pip' has no installation candidate
// 🔴 NOT GOOD
  • 2) Type this sudo apt update to update everything (just to be sure)
// output
// ...
Reading package lists... Done
Building dependency tree
Reading state information... Done
21 packages can be upgraded. Run 'apt list --upgradable' to see them.

  • 3) ✋ Since this is the module 'distutils.cmd' that is causing the issue, i will install it:
sudo apt install python3-distutils

once installed

  • read the last 5 lines, if there is nothing wrong (like missing package etc...) then it worked!, i go this:
Selecting previously unselected package python3-distutils.
(Reading database ... 226770 files and directories currently installed.)
Preparing to unpack .../python3-distutils_3.8.10-0ubuntu1~20.04_all.deb ...
Unpacking python3-distutils (3.8.10-0ubuntu1~20.04) ...
Setting up python3-distutils (3.8.10-0ubuntu1~20.04) ...


TYpe this again:

  • 1 wget https://bootstrap.pypa.io/get-pip.py

  • 2 then this python3 get-pip.py

// output of step 2
Successfully installed pip-24.1 setuptools-70.1.0 wheel-0.43.0


🌈 Now TRY to install the requests again, type the following: python -m pip install requests

 // OUTPUT
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: requests in /usr/lib/python3/dist-packages (2.22.0)

then check if you get the LIST (as that is what i want to obtain), type this to verify the whole process worked: python -m pip list

// ✅ GOOD!! it works. 🌈

requests               2.22.0 ✋

// in my machine: python -m pip install requests==2.30.0
py -m pip install requests==2.30.0
// OUTPUT
  WARNING: The script normalizer is installed in '/home/myComp/.local/bin' which is not on PATH. // 🔴 i will be solving this later
  Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
  // 🌈 success!!
