Problem Setting Up A Virtualenv
django, python, virtualenv
Solution
Seems like its been a bit since you asked this. Virtualbox's file driver for the /vagrant directory cannot recognize symbolic links which virtualenv uses a lot.
This can be best demonstrated with a simple
mybox:/vagrant$ ln -s ~/.bashrc
ln: failed to create symbolic link ./.bashrc': Protocol error`
Update:
Because of vagrant's incompatibility with symbolic links & virtualenv, my vagrant boxes/instances were task/project specific ( only 1 virtualenv). So in the vagrant host side/instance folder I would keep a short script to install python & virtualenv, then do
pip install -r /vagrant/requirement
Further documentation can be found here. https://docs.vagrantup.com/v2/provisioning/basic_usage.html
with the appropriate bash `if` checks ( does python exist, does /home/vagrant/env exist ), you can provision your box once and then append a call to activate your ~/env install so that when you login, your already setup and ready to go.
Problem
I'm trying to set up a virtualenv on Ubuntu 10.04 with Python 2.6.5 but having some issues. After having installed virtualenv and virtualenv wrapper with pip, I'm running the command: virtualenv mysite-env --verbose I get the following error: ``` Creating mysite-env/lib/python2.6 Symlinking Python bootstrap modules Symlinking mysite-env/lib/python2.6/lib-dynload Symlinking mysite-env/lib/python2.6/config Symlinking mysite-env/lib/python2.6/os.py Ignoring built-in bootstrap module: posix Symlinking mysite-env/lib/python2.6/posixpath.py Cannot import bootstrap module: nt Symlinking mysite-env/lib/python2.6/ntpath.py Symlinking mysite-env/lib/python2.6/genericpath.py Symlinking mysite-env/lib/python2.6/fnmatch.py Symlinking mysite-env/lib/python2.6/locale.py Symlinking mysite-env/lib/python2.6/encodings Symlinking mysite-env/lib/python2.6/codecs.py Symlinking mysite-env/lib/python2.6/stat.py Symlinking mysite-env/lib/python2.6/UserDict.py Symlinking mysite-env/lib/python2.6/lib-dynload/readline.so Symlinking failed, copying to mysite-env/lib/python2.6/lib-dynload/readline.so Traceback (most recent call last): File "/usr/local/bin/virtualenv", line 9, in <module> load_entry_point('virtualenv==1.6.1', 'console_scripts', 'virtualenv')() File "/usr/local/lib/python2.6/dist-packages/virtualenv.py", line 795, in main never_download=options.never_download) File "/usr/local/lib/python2.6/dist-packages/virtualenv.py", line 886, in create_environment site_packages=site_packages, clear=clear)) File "/usr/local/lib/python2.6/dist-packages/virtualenv.py", line 1020, in install_python copy_required_modules(home_dir) File "/usr/local/lib/python2.6/dist-packages/virtualenv.py", line 974, in copy_required_modules copyfile(filename, dst_filename) File "/usr/local/lib/python2.6/dist-packages/virtualenv.py", line 414, in copyfile copyfileordir(src, dest) File "/usr/local/lib/python2.6/dist-packages/virtualenv.py", line 391, in copyfileordir shutil.copy2(src, dest) File "/usr/lib/python2.6/shutil.py", line 99, in copy2 copyfile(src, dst) File "/usr/lib/python2.6/shutil.py", line 53, in copyfile fdst = open(dst, 'wb') IOError: [Errno 20] Not a directory: 'mysite-env/lib/python2.6/lib-dynload/readline.so' ``` If I run it again, I get the following: ``` Directory mysite-env/lib/python2.6 already exists Symlinking Python bootstrap modules Ignoring built-in bootstrap module: posix Cannot import bootstrap module: nt Symlinking mysite-env/lib/python2.6/lib-dynload/readline.so Symlinking mysite-env/lib/python2.6/copy_reg.py Symlinking mysite-env/lib/python2.6/types.py Symlinking mysite-env/lib/python2.6/re.py Symlinking mysite-env/lib/python2.6/sre.py Symlinking mysite-env/lib/python2.6/sre_parse.py Symlinking mysite-env/lib/python2.6/sre_constants.py Symlinking mysite-env/lib/python2.6/sre_compile.py Ignoring built-in bootstrap module: zlib Symlinking mysite-env/lib/python2.6/warnings.py Symlinking mysite-env/lib/python2.6/linecache.py Symlinking mysite-env/lib/python2.6/_abcoll.py Symlinking mysite-env/lib/python2.6/abc.py Creating mysite-env/lib/python2.6/site-packages Writing mysite-env/lib/python2.6/site.py Writing mysite-env/lib/python2.6/orig-prefix.txt Creating parent directories for mysite-env/include Symlinking mysite-env/include/python2.6 Creating mysite-env/bin New python executable in mysite-env/bin/python Changed mode of mysite-env/bin/python to 0755 Testing executable with mysite-env/bin/python -c "import sys; print(sys.prefix)" ERROR: The executable mysite-env/bin/python is not functioning ERROR: It thinks sys.prefix is u'/usr' (should be '/vagrant/mysite-env') ERROR: virtualenv is not compatible with this system or executable ``` Any ideas how to fix this? Thanks!
