I get the following error message when trying to set up a virtual environment with virtualenv 15.0.2 but receive OSError setuptools pip wheel failed with error code 1.

You can get virtualenv to work with conda if you downgrade python to 2.7.9:

$pip install python=2.7.9

You can see the status of this issue on conda's github: https://github.com/conda/conda/issues/1367

I tried for hours, read lots of posts and finally find a way out.

pip uninstall virtualenv conda install virtualenv

The reason is the virtualenv installed by pip is not compatible with conda. I don't know more details, but it works for me.

I had this same issue while installing requirements from requirements.txt.

This was what solved the problem for me.

  1. pip install --upgrade virtualenv

  2. pip install --upgrade pip

  3. After doing this, if you ever get errors while trying to install a dependency like below

THESE PACKAGES DO NOT MATCH THE HASHES FROM THE REQUIREMENTS FILE. If you have updated the package versions, please update the hashes. Otherwise, examine the package contents carefully; someone may have tampered with them. pbr==3.1.1 from https://pypi.python.org/packages/0c/5d/b077dbf309993d52c1d71e6bf6fe443a8029ea215135ebbe0b1b10e7aefc/pbr-3.1.1-py2.py3-none-any.whl#md5=75a0f55856bfc9220af0d01244afec43 (from -r requirements-test.txt (line 52)):

Got b11776d9eb0e7b3988bb7bdef4e2d40cf8c168214374d12d1c4495c1346ac10b

ERROR: could not install deps [-rrequirements-test.txt]; v = InvocationError('/app/.tox/py27/bin/pip install -rrequirements-test.txt (see /app/.tox/py27/log/py27-1.log)', 1)

Then use pip --no-cache-dir install <package-name> to install the package; where <package-name> is the name of the package you want to install.

e.g pip --no-cache-dir install pbr

I got this error while having several python versions installed on my mac. Specifying which python version to be used for your new virtual environment solves the issue. For example if you want to use python 2.7:

virtualenv -p /usr/bin/python2.7 venv

Anaconda does seem to sometimes mess up with virtualenv.

Specifying the python system version /usr/bin/python3.5 instead of the conda one solved the issue.
