Here is the write-up I posted over on the pyenv issues page:
This is apparently a behavior issue in the way venv works. Not only does this
impact 3.6.x, I also confirmed that the same issue occurs with venv in general
using the stock 3.5 Python that comes with Ubuntu 16.04.
The trouble is at 3.6/Lib/venv/__init__.py:111. Starting at line 111:
if sys.platform == 'darwin' and '__PYVENV_LAUNCHER__' in env:
executable = os.environ['__PYVENV_LAUNCHER__']
else:
executable = sys.executable
dirname, exename = os.path.split(os.path.abspath(executable))
context.executable = executable
This carries down to the setup_python method starting at line 187
(3.6/Lib/venv/__init__.py:187). It takes whatever executable that is called as
the source, and then creates the others based on a hard coded list (e.g. python
and python3).
def setup_python(self, context):
"""
Set up a Python executable in the environment.
:param context: The information for the environment creation request
being processed.
"""
binpath = context.bin_path
path = context.env_exe
copier = self.symlink_or_copy
copier(context.executable, path)
dirname = context.python_dir
if os.name != 'nt':
if not os.path.islink(path):
os.chmod(path, 0o755)
for suffix in ('python', 'python3'):
path = os.path.join(binpath, suffix)
if not os.path.exists(path):
# Issue 18807: make copies if
# symlinks are not wanted
copier(context.env_exe, path, relative_symlinks_ok=True)
if not os.path.islink(path):
os.chmod(path, 0o755)
else:
subdir = 'DLLs'
include = self.include_binary
files = [f for f in os.listdir(dirname) if include(f)]
for f in files:
src = os.path.join(dirname, f)
dst = os.path.join(binpath, f)
if dst != context.env_exe: # already done, above
copier(src, dst)
dirname = os.path.join(dirname, subdir)
if os.path.isdir(dirname):
files = [f for f in os.listdir(dirname) if include(f)]
for f in files:
src = os.path.join(dirname, f)
dst = os.path.join(binpath, f)
copier(src, dst)
# copy init.tcl over
for root, dirs, files in os.walk(context.python_dir):
if 'init.tcl' in files:
tcldir = os.path.basename(root)
tcldir = os.path.join(context.env_dir, 'Lib', tcldir)
if not os.path.exists(tcldir):
os.makedirs(tcldir)
src = os.path.join(root, 'init.tcl')
dst = os.path.join(tcldir, 'init.tcl')
shutil.copyfile(src, dst)
break
If you don't call -m venv as python3.X, you will never get that binary in the
bin directory.
