IOError: [Errno 62] Too many levels of symbolic links

I cant create a venv with the name PYTHON_27 (with underscore)

> mkvirtualenv PYTHON_27 -p Python2.7
Running virtualenv with interpreter /usr/local/bin/Python2.7

    with open(dst, 'wb') as fdst:

But no problem with name PYTHON-27

Works on Sierra

$ python2.7 -m virtualenv PYTHON_27
New python executable in /Users/yen/PYTHON_27/bin/python

Could you paste the output of direct virtualenv invocations?

[Tset-Noitamotua]

Indeed ... virtualenv PYTHON_27 worked.

So then it may be an issue of virtualenvwrapper?

Most likely that's it.

[Tset-Noitamotua]

I've posted it on virtualenvwrapper's issue tracker on bitbucket. So let's close this one.

for the curious, the virtualenvwrapper ticket is this one: https://bitbucket.org/virtualenvwrapper/virtualenvwrapper/issues/288/ioerror-errno-62-too-many-levels-of (still open as of this moment).
