Problem with installing Python in external drive

I am a beginner in Python and PyCharm. I had installed both Python and PyCharm in my D drive, instead of C. But then, I was facing some issues, so had to uninstall and reinstall them in my C drive. Now, when I use the pip command in CMD, it says
Fatal error in launcher: Unable to create process using '"D:\Program Files\Python\python.exe" "C:\Users\USERNAME\AppData\Local\Programs\Python\Python39\Scripts\pip.exe" ': The system cannot find the file specified.
I tried looking for solutions but have given up. Does anyone have any suggestions?

This is because your path file is still leading to the pip in D: Go to path and change that to your C: directory for pip

Try to install via Python website it could fix your terminal issues.
In PyCharm settings you can change your Python environnement (tutorial here).

I also had the same problem and I tried the following steps:
Open CMD as an administrator.
Write 'python -m pip install -U --force pip' in the CMD.
Restart your PC/laptop.
Try the pip command now.

How to create an executable with a pycharm python file though pyinstaller?

I have been trying to install pyinstaller in order to create an executable of a python project I have been working on, but my pip command simply doesn't work. This is the error I would get "'pip' is not recognized as an internal or external command, operable program or batch file". I have already checked the interpreter of my pycharm project, and it shows that it has pip already installed. I tried to look this up online, and I found out that a problem could be that the environment variable Path just needs to have the directory of my python version, but even after doing this, it still would not work. For additional information, I already tried to find the directory by using the command "where python" in the command prompt, but that path didn't work, and I'm using windows 10.

Usually for most of users, there would be a problem as you mention above. In such situation, you just need to install pip again with command like
python -m pip3 install -U pip
and remember next time, if pip reminds you to upgrade it, do not just use
pip install -U pip

Unable to do pip install pandas-profiling

I've tried severally to install Pandas-Profiling on my windows 10 cmd using "pip install pandas-profiling" but it doesn't work. I've also tried installing it on conda but its the same story. I need help installing this please.

I also had the same problem. It didn't work with a normal pip install. I fixed it by running the following command in anaconda prompt:
conda install -c anaconda pandas-profiling
You can find the full documentation here.
Hope it helps :)

if you don't provide the error message, we can't help you.
If you have the following error message:
'pip' is not recognized as an internal or external command,
operable program or batch file.
It means that Python is not added to your Path environment variable. How to fix it:
First solution: Adding Python to the Path by going in your environment variables, in System Variables click on Path then Edit, and in the grid, add your Python's path (which may be C:\Users\<user>\AppData\Local\Programs\Python\Python<version>\). You can also add Python yo the Path by uninstall it and install it again and in the installer, make sure you check "Add Python to PATH"
Second solution: You can run pip by putting python3 -m before you pip command, like that: python3 -m pip install pandas-profiling.

I have been able to find a solution to the error message. I had to install the Microsoft C++ Build Tools, then I launched it and did the installation through it using ‘pip install pandas-profiling’ you can download using the link https://visualstudio.microsoft.com/visual-cpp-build-tools/

For me it only works also if putting "py"
so:
py -m pip install pandas-profiling
In the command prompt.

How do I use pip install?

When I look up tutorials on Python almost every one starts with "Start of with pip install bs4" but they never tell me about how. Because when I write "pip install bs4" in my cmd the answer I get is only
'pip' is not recognized as an internal or external command,
operable program or batch file.
I've tried running "pip install bs4" in PyCharm as well but nothing works.
I am a totally a beginner, which you probably already noticed, and just want to get beautifulsoup.

I'm going to assume you're on Windows since your error message contains "batch file". Try:
py -m pip install bs4
The -m flag will import the pip module, and allow you to run the install command. If running py doesn't work, try the absolute path to your python.exe.

This is the official site that shows you how to download and install python pip
pretty much just download the file, open up the command prompt, cd to file directory and run it with:
python get-pip.py

how to set pip environment path?

I ran:
python -m pip --version
And it returned:
pip 8.1.2 from C:\Users\myonl\AppData\Local\Programs\Python\Python35-32\lib\site-packages (python 3.5)
So I set my path to the above, but when I try to actually use pip I get:
pip install PyQt4
'pip' is not recognised as an internal or external command, operable program or batch file.
What am I doing wrong?

The first time you do python -m pip, the second time you do pip.
pip is not on your PATH, but python is. You can fix that, or you can call it using python -m pip.
Also possible is that you simply need to refresh your console window so it picks up the change you've made to PATH. Try closing your terminal and re-opening it and seeing if you have the same problem.
