Python pip wheel failed with error

Cannot create virtual environment with «setuptools pip wheel failed with error code 1»

I’m using Windows 10 with Python 3.5 64bit. And installed virtualenv from pip. When trying to create a new virtual environment, it tends to fail with the following logging:

What is the meaning of «Failed building wheel for X» in pip install?

This is a truly popular question here at SO, but none of the many answers I have looked at, clearly explain what this error really mean, and why it occurs. One source of confusion, is that when (for example) you do pip install pycparser , you first get the error: Failed building wheel for pycparser which is then followed by the message that the package was: Successfully installed pycparser-2.19 .

# pip3 install pycparser Collecting pycparser Using cached https://files.pythonhosted.org/packages/68/9e/49196946aee219aead1290e00d1e7fdeab8567783e83e1b9ab5585e6206a/pycparser-2.19.tar.gz Building wheels for collected packages: pycparser Running setup.py bdist_wheel for pycparser . error Complete output from command /usr/bin/python3 -u -c "import setuptools, tokenize;__file__='/tmp/pip-install-g_v28hpp/pycparser/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" bdist_wheel -d /tmp/pip-wheel-__w_f6p0 --python-tag cp36: Traceback (most recent call last): File "", line 1, in .

What is going on here? (I would like to understand how something can fail but still get installed and whether you can trust this package functioning correctly?) So far the best partial explanation I have found is this.

Could not build wheels for _ which use PEP 517 and cannot be installed directly — Easy Solution

I am trying to install a package which uses PEP 517. The newest version of Pip won’t allow me to install due to an error involving wheel building for 517. In the past, I’ve solved this issue by downgrading Pip, installing the package and Upgrading Pip back to the latest version. However, after I downgrade pip in my virtualenv, if I try to run ‘Pip install black’ I get the No module named ‘pip._internal.cli.main’ error. How can I solve this?

I had similar issues installing pytype on windows. The solution was to use an older version of the lib. see github issue

There are system dependencies for the package pypi.org/project/pypotrace (scroll down). As o0lemon_pie0o answered, check what libraries/packages you are missing with the verbose flag. (I’m using OSX and missing libagg library)

The easiest solution to deal with the error

"Could not build wheels for ____ which use PEP 517 and cannot be installed directly" 

sudo pip3 install _____ --no-binary :all: 

Where ____ is obviously the name of the library you want to install.

RROR: Command errored out with exit status 1: /usr/bin/python3 /usr/local/lib/python3.6/dist-packages/pip install —ignore-installed —no-user —prefix /tmp/pip-build-env-ereh_rp4/normal —no-warn-script-location -v —no-binary :all: —only-binary :none: -i pypi.org/simple — ‘cffi>=1.0.0’ Check the logs for full command output. i got this error now

Does not work for me. A comment would help why you think this suggestion would help. Also installing pip using sudo isn’t a good idea. The OP obviously uses a virtual environment.

Your self-answer didn’t work for me, i got the same error as @SandrinJoy while running in msys shell in a windows 7 vm.

This error came up for the h5py library during the installation of Tensorflow. I checked the h5py documentation to make sure I had the right versions of pip and setuptools, https://pip.pypa.io/en/stable/reference/pip/.

pip install --upgrade pip setuptools wheel 

I then checked the error log to identify what has caused h5py to fail while installing backend dependencies. I identified it was the libhdf5.so, where it says «error: libhdf5.so cannot open shared object file: No such file or directory». I installed the library by running:

sudo apt-get install libhdf5-dev 

After this, the h5py installed successfully alongside TensorFlow. I’ve come across similar PEP 517 errors caused by missing dependencies:
