Hi All, I'm seeing this exception when running a particular buildout on Windows: C:\Jenkins\workspace\checker-buildout\aeb5917b>bin\buildout Develop: 'C:\\Jenkins\\workspace\\checker-buildout\\aeb5917b\\.' Installing py. Generated script 'C:\\Jenkins\\workspace\\checker-buildout\\aeb5917b\\bin\\checker'. Generated script 'C:\\Jenkins\\workspace\\checker-buildout\\aeb5917b\\bin\\tox'. Generated script 'C:\\Jenkins\\workspace\\checker-buildout\\aeb5917b\\bin\\tox-quickstart'. While: Installing py. An internal error occurred due to a bug in either zc.buildout or in a recipe being used: Traceback (most recent call last): File "c:\users\jenkins\.buildout\eggs\zc.buildout-1.7.1-py2.7.egg\zc\buildout\buildout.py", line 1866, in main getattr(buildout, command)(args) File "c:\users\jenkins\.buildout\eggs\zc.buildout-1.7.1-py2.7.egg\zc\buildout\buildout.py", line 625, in install installed_files = self[part]._call(recipe.install) File "c:\users\jenkins\.buildout\eggs\zc.buildout-1.7.1-py2.7.egg\zc\buildout\buildout.py", line 1345, in _call return f() File "c:\users\jenkins\.buildout\eggs\zc.recipe.egg-1.3.2-py2.7.egg\zc\recipe\egg\egg.py", line 173, in install return self._install(reqs, ws, scripts) File "c:\users\jenkins\.buildout\eggs\zc.recipe.egg-1.3.2-py2.7.egg\zc\recipe\egg\egg.py", line 195, in _install relative_paths=self._relative_paths File "c:\users\jenkins\.buildout\eggs\zc.buildout-1.7.1-py2.7.egg\zc\buildout\easy_install.py", line 1223, in scripts initialization, executable, arguments) File "c:\users\jenkins\.buildout\eggs\zc.buildout-1.7.1-py2.7.egg\zc\buildout\easy_install.py", line 1350, in _generate_scripts module_name, attrs, arguments, block_site=block_site)) File "c:\users\jenkins\.buildout\eggs\zc.buildout-1.7.1-py2.7.egg\zc\buildout\easy_install.py", line 1498, in _script return _write_script(dest, contents, 'script') File "c:\users\jenkins\.buildout\eggs\zc.buildout-1.7.1-py2.7.egg\zc\buildout\easy_install.py", line 1463, in _write_script open(exe, 'wb').write(new_data) IOError: [Errno 13] Permission denied: 'C:\\Jenkins\\workspace\\checker-buildout\\aeb5917b\\bin\\buildout.exe' This happens every time, on Python 2.5, 2.6 and 2.7. I've tried blowing the workspace away, makes no difference: http://jenkins.simplistix.co.uk/job/checker-buildout/114/PYTHON=2.7,label=wi... http://jenkins.simplistix.co.uk/job/checker-buildout/114/PYTHON=2.6,label=wi... http://jenkins.simplistix.co.uk/job/checker-buildout/114/PYTHON=2.5,label=wi... Any idea what's going on here and how I can fix it? cheers, Chris -- Simplistix - Content Management, Batch Processing & Python Consulting - http://www.simplistix.co.uk
