I downloaded the newest Cython release from https://pypi.python.org/pypi/Cython/#downloads. I'm working in Python 3.5.1 on a Mac so I downloaded
Cython-0.26.1-cp35-cp35m-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.macosx_10_10_intel.macosx_10_10_x86_64.whl
I unzipped it and entered the /Cython directory, but there is no setup.py in the directory. When I try to run python3 setup.py install anyway I get the following error:
/usr/local/Cellar/python3/3.5.1/Frameworks/Python.framework/Versions/3.5/Resources/Python.app/Contents/MacOS/Python: can't open file 'setup.py': [Errno 2] No such file or directory
It doesn't seem to be looking in the /Cython directory I am in, but there is also no setup.py in that directory.
Not sure what's going on, I can't seem to find anyone else having this issue.
I've install python3 using homebrew.
The file you downloaded is a wheel file that should be installed using pip. The wheel file does not include the setup.py script which is required to build the package but is not used when installing wheels. First check you are using correct pip command (you need one for python 3.5), this is usually pip3.5 or pip3 command:
$ pip3 -V
pip 9.0.1 from /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages (python 3.5)
To install cython from the downloaded wheel, issue
$ pip3 install path/to/downloaded.whl
Or simply issue
$ pip3 install cython
as pip will download the latest package wheel for you. Since you installed python 3.5 via Homebrew, you probably have to switch to the user you use to install packages with Homebrew or the installation with pip will fail.
Note that, although suggested in the comments, it is not advised to install cython package via brew install:
$ brew info cython
...
==> Caveats
This formula is keg-only, which means it was not symlinked into
/usr/local,
because this formula is mainly used internally by other formulae.
Users are advised to use `pip` to install cython.
I tried to install a python package using setup.py but failed.
Any idea about that? I am on Ubuntu 14.04.
pip install setup.py
You just mixed up something.Have a look at pip install usage and Installing Python Modules.
If you want to download a module source distribution and install it, you should unpack the archive into a similarly-named directory: foo-1.0. Additionally, the distribution will contain a setup script setup.py,and then run this command from a terminal:
python setup.py install
You can use pip install if you want to install packages from:
PyPI (and other indexes) using requirement specifiers.
VCS project urls.
Local project directories.
Local or remote source archives.
Hope this helps.
Use the following:
python setup.py install
Try this python setup.py install
Navigate to the folder containing the package
eg: cd /Desktop/packages/foo-1.0/
you can install the package either by
python setup.py install
or by
pip install ./
in Linux use
sudo python3 setup.py install
I'm new to virtualenv (on windows). I'm trying to use pip (1.5) install a local wheel file, but it is failing.
The command is:
pip install --no-index -f C:/Users/<User>/Download openpyxl
In the pip.log, I can see where it finds the correct file, but then doesn't try to install it:
Skipping link file:///C:/Users/<User>/Download/openpyxl-1.7.0-py2.py3-none-any.whl; unknown archive format: .whl
I have wheel (version 0.22) install globally as well as in the virtual environment. Any idea how I can get .whl to be a recognized format?
It appears wheel support is disabled.
Make sure that you have setuptools version 0.8 or newer installed, and that the use-wheel option is not set to false in $HOME/.pip/pip.conf.
Upgrading setuptools is easy enough if pip is already working:
pip install --upgrade setuptools
but note that older virtualenv versions can depend on older setuptools versions; you'll need to make sure that virtualenv is also up to date.
I have bumped into the same problem with wheel when downloaded requirements with:
pip install --download /pip_mirror six django_debug_toolbar
dir2pi /pip_mirror/
and tried to install them with:
pip install six-1.7.3-py2.py3-none-any.whl
Even though there is no any config at $HOME/.pip/pip.conf and
$ easy_install --version
setuptools 5.4.1
I still get:
unknown archive format: .whl
I have managed to avoid the problem by adding --no-use-wheel like this, so got only tar.gz files (instead of .whl)
pip install --no-use-wheel --download /pip_mirror six django_debug_toolbar
dir2pi /pip_mirror/
After this pip install --index-url=file:///pip_mirror/simple/ six went without any problems
I'm having troubles with installing packages in Python 3.
I have always installed packages with setup.py install. But now, when I try to install the ansicolors package I get:
importerror "No Module named Setuptools"
I have no idea what to do because I didn't have setuptools installed in the past. Still, I was able to install many packages with setup.py install without setuptools. Why should I get setuptools now?
I can't even install setuptools because I have Python 3.3 and setuptools doesn't support Python 3.
Why doesn't my install command work anymore?
Your setup.py file needs setuptools. Some Python packages used to use distutils for distribution, but most now use setuptools, a more complete package. Here is a question about the differences between them.
To install setuptools on Debian:
sudo apt-get install python3-setuptools
For an older version of Python (Python 2.x):
sudo apt-get install python-setuptools
EDIT: Official setuptools dox page:
If you have Python 2 >=2.7.9 or Python 3 >=3.4 installed from
python.org, you will already have pip and setuptools, but will need to
upgrade to the latest version:
On Linux or OS X:
pip install -U pip setuptools
On Windows:
python -m pip install -U pip setuptools
Therefore the rest of this post related to Distribute is obsolete (e.g. some links don't work).
EDIT 2022-02-04
From Python 3.10 Distutils is deprecated and will be removed in Python 3.12 - use setuptools:
The entire distutils package is deprecated, to be removed in Python 3.12. Its functionality
for specifying package builds has already been completely replaced by
third-party packages setuptools and packaging ...
Distribute (deprecated)
Distribute - is a setuptools fork which "offers Python 3 support". Installation instructions for distribute(setuptools) + pip:
curl -O http://python-distribute.org/distribute_setup.py
python distribute_setup.py
easy_install pip
Similar issue here.
UPDATE: Distribute seems to be obsolete, i.e. merged into Setuptools: Distribute is a deprecated fork of the Setuptools project. Since the Setuptools 0.7 release, Setuptools and Distribute have merged and Distribute is no longer being maintained. All ongoing effort should reference the Setuptools project and the Setuptools documentation.
You may try with instructions found on setuptools pypi page (I haven't tested this, sorry :( ):
wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | python
easy_install pip
Make sure you are running the latest version of pip
I tried to install Ansible and it failed with
ModuleNotFoundError: No module named 'setuptools_rust'
python3-setuptools was already in place, so upgrading pip solved it.
pip3 install -U pip
I was doing this inside a virtualenv on Oracle Linux 6.4 using Python 2.6, so the apt-based solutions weren't an option for me, nor were the Python 2.7 ideas. My fix was to upgrade my version of setuptools that had been installed by virtualenv:
pip install --upgrade setuptools
After that, I was able to install packages into the virtualenv.
The solution which worked for me was to upgrade my setuptools:
python3 -m pip install --upgrade pip setuptools wheel
For others with the same issue due to a different reason: This can also happen when there's a pyproject.toml in the same directory as the setup.py, even when setuptools is available.
Removing pyproject.toml fixed the issue for me.
pip uninstall setuptools
and then:
pip install setuptools
This works for me and fixes my issue.
When there's a pyproject.toml in the same directory as the setup.py, it can be the cause of the issue. I renamed that file, but it didn't solve the issue, so I restablished the original file name, and did the following change.
Under the [build-system] section, I added "setuptools" to the requires= list, and it worked.
First step #1
You have to install setuptools
On Linux:
pip install -U pip setuptools
On Mac OS:
pip install -U pip setuptools
On Windows:
python -m pip install -U pip setuptools
Second step #2
Make sure you have made it accessible (make it available in environmental variables)
On Linux
export PATH="INSTALLATIONDIRECTORY:$PATH"
On Mac OS
Sorry, I don't know.
On Windows
Open the Start Search, type in “env”, and choose “Edit the system environment variables”
Click the “Environment Variable” button.
Set the environment variables as needed. The New button adds an additional variable.
Dismiss all of the dialogs by choosing “OK”. Your changes are saved!
The distribute package provides a Python 3-compatible version of setuptools: http://pypi.python.org/pypi/distribute
Also, use pip to install the modules. It automatically finds dependencies and installs them for you.
It works just fine for me with your package:
[~] pip --version
pip 1.2.1 from /usr/lib/python3.3/site-packages (python 3.3)
[~] sudo pip install ansicolors
Downloading/unpacking ansicolors
Downloading ansicolors-1.0.2.tar.gz
Running setup.py egg_info for package ansicolors
Installing collected packages: ansicolors
Running setup.py install for ansicolors
Successfully installed ansicolors
Cleaning up...

this is how my problem was solved => pip3 install setuptools-rust
If you want to check your list => pip3 list
i faced this problem while trying to install elastalert2
System informations
CentOS Linux release 7.9.2009 (Core)
Python 3.6.8
pip 21.3.1 from /usr/local/lib/python3.6/site-packages/pip (python 3.6)
I ran into this problem when my pip requirements.txt file contained an editable library that was built using poetry and contained a pyproject.toml file. Following the documentation for setuptools, my solution was to add setuptools to the build-system requirements in the pyproject.toml file as follows:
[build-system]
requires = ["poetry-core>=1.0.0", "setuptools"]
build-backend = "poetry.core.masonry.api"
If pip isn't installed, like for example if it's coming from the Deadsnakes PPA, or a Docker environment, the best way to fix this error is by bootstrapping it by running
python -m ensurepip
Windows 7:
I have given a complete solution here for Python Selenium WebDriver:
Setup easy install (Windows - simplified)
download ez.setup.py (https://bootstrap.pypa.io/ez_setup.py) from 'https://pypi.python.org/pypi/setuptools'
move ez.setup.py to C:\Python27\
open cmd prompt
cd C:\Python27\
C:\Python27\python.exe ez.setup.py install
I ran sudo python setup.py build_ext -i and it failed with No module named setuptools.
I solved it with this command:
<i>sudo apt-get install python-setuptools</i>
A few years ago I inherited a Python (2.7.1) project running under Django-1.2.3 and now was asked to enhance it with QR possibilities. I got the same problem and did not find pip or apt-get either. So I solved it in a totally different, but easy way.
I /bin/vi-ed the setup.py and changed the line
"from setuptools import setup"
into:
"from distutils.core import setup"
The PyPA recommended tool for installing and managing Python packages is pip. pip is included with Python 3.4 (PEP 453), but for older versions here's how to install it (on Windows):
Download https://bootstrap.pypa.io/get-pip.py
>c:\Python33\python.exe get-pip.py
Downloading/unpacking pip
Downloading/unpacking setuptools
Installing collected packages: pip, setuptools
Successfully installed pip setuptools
Cleaning up...
>c:\Python33\Scripts\pip.exe install pymysql
Downloading/unpacking pymysql
Installing collected packages: pymysql
Successfully installed pymysql
Cleaning up...
On macOS, if you have homebrew installed, simply run:
brew install rust
If you still find this issue, try this:
python3 -m pip install scrapy --upgrade --force --user
While trying to install socketIO I had the same issue. At my system (Windows 11) setupTools were there twice. At C:\Program Files\Python310\Lib\site-packages\ and at C:\Users\user\AppData\Roaming\Python\Python310\site-packages\
Had to uninstall one of them.
Working on Debian, sometime it can be because of older pip version. Therefore, update pip>
python -m pip install -U pip
I had such a problem to install pyunicorn. I wanted to install it on Google Colab. I tried installing pyunicorn directly from Github and it worked for me. For example in my case it was like this:
pip install git+https://github.com/pik-copan/pyunicorn.git#egg=pyunicorn
