I have installed the oct2py package using the pip command pip install oct2py, set the environement path of python, pip and octave as in the following picture:
However, whenever I try to import it in my python script, I get the following error:
I checked whether the package is installed, it says: Requirement satisfied.
Any ideas of what I could possibly be doing wrong?
I am trying to install to oct2py package to import in my python script. However whenever I run the command pip install oct2py I get the following error:
Fatal error in launcher: Unable to create process using '"c:\python37\python.exe" "C:\Program Files\Python37\Scripts\pip.exe" ': file cannot be found.
How can I install oct2py?
Found the answer
Deinstalled python and reinstalled it. I checked the environment variable and changed it from this one : 'C:\Program Files\Python39' to this one 'C:\Users\lsee\AppData\Local\Programs\Python\Python39'.
Is unable to locate your pip installer, easy fix is unusually to either upgrade or test pip :
# to upgrade your pip
python -m pip install --upgrade pip
pip --version
# test you have pip in your machine
If your pip version is showing that means you have it installed, it could be a problem activating your virtual environnement, or your path.
It says the file cannot be locate, are you sure your path for Python and pip is correct ?
Try:
python -m pip install oct2py
This should work (as python -m pip install gave not errors)
I have installed pip for python 3.6 on Ubuntu 14. After I run
sudo apt-get install python3-pip
to install pip3, it works very well. However, after installation, when I am trying to run
pip3 install packagename
to install a new package, something strange occurs:
File "/usr/lib/python3/dist-packages/pkg_resources.py", line 1479, in <module>
register_loader-type(importlib_bootstrap.SourceFileLoader, DefaultProvider)
AttributeError: module "importlib._bootstrap" has no attribute "SourceFileLoader"
It seems that I did nothing wrong, and I really cannot figure out the reason.
If you're getting this error running pip install dotenv, this is because the package is called python-dotenv not dotenv.
This worked for me:
sudo pip install python-dotenv
Faced the same problem. I think this is because python3.6 and pip3 were installed from different sources.
I suggest using python's inbuilt facility to install pip i.e
python3 -m ensurepip --upgrade
This should install pip3 and pip3.x where x in python3.x.
Same works for python2 also.
Tried to install Tensorflow in venv on Windows 10 machine with python 3.8 and got the same issue.
What helped for me was:
pip install setuptools --upgrade
I had the same problem on my ubuntu 18.04 with python 3.6. None of the above methods helped, but this one solved the problem:
pip3 uninstall setuptools
I had the same error whatever I asked to pip. I gave a look to this page: https://packaging.python.org/tutorials/installing-packages/
That line is the one that solved my problem:
python3 -m pip install --upgrade pip setuptools wheel
pip install setuptools --upgrade
This command solved my issue. It fixed my problem.
When updating from python3.4 to python3.6 on ubuntu 14.04. The following solved me:
wget https://bootstrap.pypa.io/ez_setup.py -O - | python3
If you face this issue in anaconda environment, simply upgrade setuptools using the following:
conda install -c conda-forge setuptools
That's because you are using an old version of setuptools, check up this issue.
I met the same problem, this is the key:
curl -sS https://bootstrap.pypa.io/get-pip.py | sudo python3
I had faced the same issue on Ubuntu 19.10 and now I upgraded to Ubuntu 20.04 and faced the issue again. This issue is due to broken pip3. So whenever you enter pip3 and hit enter it will show the same error. So instead of using "pip3 uninstall setuptools" use the below code
python3 -m pip uninstall setuptools
It resolved my issue 3rd time
I am facing the same problem, which is solved by downloading the source files of the setuptools and installing the module manually.
The setuptools can be downloaded here:
https://pypi.org/project/setuptools/
After downloading, unzip the package first, then cd to the directory and run
python setup.py install --user
For me the error happened while trying to create a virtual env with python 3.8:
sudo virtualenv venv -ppython3.8
And after trying all the answers here, finally the problem solved by installing the new version of virtualenv (20.0.7):
sudo pip3 install virtualenv
I encountered this error message triggered by a slightly different situation which I'll mention here for anyone who finds this.
This same error also occurs when installing the distribute Python package (which is currently just a compatibility layer in front of setuptools) in Python 3.6 or newer.
In my specific situation I discovered this as I was using pyzmail which has been somewhat abandoned and depends on distribute.

I had the same issue when I tried to install the Slate package in Windows 10, Python 3.7.4 version:
AttributeError: module 'importlib._bootstrap' has no attribute 'SourceFileLoader'
The instruction that generated the error:
C:\WINDOWS\system32>python -m pip install slate
The instruction that worked:
C:\WINDOWS\system32>python -m pip install https://github.com/timClicks/slate/archive/master.zip
I had the same problem with my cloud computer. If all above didn't work for you don't worry. Here's how I resolved it:
Download the pip file (pip-version.tar.gz) from:
https://pypi.org/project/pip/#files
For cloud, use this
curl https://files.pythonhosted.org/packages/8e/76/66066b7bc71817238924c7e4b448abdb17eb0c92d645769c223f9ace478f/pip-20.0.2.tar.gz --output pip.tar.gz
Extract the content of the file and cd into the directory.
Run the following in the directory
python3 setup.py install --user
You should have pip3 working without errors.
pip3 install setuptools --upgrade
This also cured the issue on Python 3.9 running on Windows 10 and even on a custom Docker image.
I was having the same issue while using docker-compose. This exact error can be caused by not being the root user. Running the same commands with sudo fixed it for me. I don't not have setup-tools installed, and I'm running pip3. My issue was that IntelliJ didn't have sudo rights, so i had to do it from the terminal.
Above solutions were not working in my case for Ubuntu 20
If you run the following command:
sudo apt install python3-setuptools
Then you might get the result:
Reading package lists... Done
Building dependency tree
Reading state information... Done
python3-setuptools is already the newest version (45.2.0-1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
But to actually solve it and re-install setuptools try following commands:
sudo apt download python3-setuptools
sudo dpkg -i python3-setuptools_45.2.0-1_all.deb
Note: Change the version of the python package that is downloaded

Mine looked pretty similar, but for some reason I had a python installation in my home directory .local folder.
I did some of the other answers in this thread to ensure I had good local copy of python, then did:
rm -rf ~/.local
Just go inside the /usr/lib/python3/dist-packages/, first copy setuptools file somewhere and then delete the setuptools. Everything will be okay for deleting you can use:
sudo rm -r setuptools
for copying
sudo cp -r setuptools /...Desktop/
After that if it gives errors just:
sudo pip3 install setuptools==3.8.1
to download again.
I was trying to install spyder on windows 10 with the python version 3.6+. But it was not working. It was giving me the following error. Seriously, i don't know what these error means. Error:

I just deleted all the previous version of the python from the C drive manually.
then, install the python 3.6.5(latest stable version available) at the time of posting.
Sometimes i faced issues in installing python and access it through windows cmd.
To resolve this, during the installation of python 3.6.5, opt for customized installation and when it ask for the folder in which to install it.
just create a folder in C drive with name Python36 and install python in this folder. Means install python in C:\Python36
and add two paths to the Path variable using the following commands.
setx path "%path%;C:\Python36;"
setx path "%path%;C:\Python36\Scripts;"
and then, try python.
To check, just type python --version
if it is working, python is ready to use
Then, i tried to install SIP package from pip. but pip was not working.
then, i manually install and upgrade the pip on my system using the following commands windows command line,
python -m pip install pip==9.0.0 # will install pip
pip install -U pip # will upgrade pip
pip got installed successfully and the version i checked was
pip 9.0.3 using the following command on windows command line:
pip --version
After that just run the following commands from cmd:
pip3 install SIP
pip3 install PyQt5
pip install spyder
Then, to check either spyder is working or not, just go the directory in which python is installed. e.g. on my sysytem, directory is C:\Python36\Scripts. search for spyder3app and click on it. and create a shortcut for it.
Versions:
PyQt5 (5.9.2)
sip (4.19.8)
Install the spyder using pip:
pip install spyder
I have created a virtual environment for python3
virtualenv -p /usr/bin/python3 myenv
Everything works ok and pip installs python3 packages. Then I need to upgrade my python3.2 to python3.3. I am using ubuntu 12.04, so I need to do what Luper Rouch suggests here through ppa
I copy /usr/bin/python3.3 into myenv/bin/python3, thus (inside myenv):
python --version
returns Python 3.3.5. But then pip stops working failing with
pip install urllib3
Traceback (most recent call last):
File "mypathtoevn/bin/pip", line 7, in <module>
from pip import main
ImportError: No module named 'pip'
Then I understand that I have to use
pip3.3 install <package_name>
but I can't find any other pip*.* version either globally or inside virtualenv in my system.
How can I get pip3.3 or any other pip version?
Thanks
The ppa you have installed does not contain pip. The python package installer is itself installed with easy_install. On the question you linked to follow the later parts of this answer
Basically, calling
wget http://python-distribute.org/distribute_setup.py
python distribute_setup.py
easy_install pip
should be sufficient. You should use the easy_install command of your Python3.3 install.
Check with
which python
where your python comes from, and search for easy_install in that path. In your case you know where it resides: Your virtualenv.
