I assume this is to avoid copying the wrong +file on systems where it is possible to find incompatible libraries by +accident. Adding "/nix/store" to the prefix fixes this problem. + +A sitecustomize.py is created in the virtualenv which makes libraries +from the python specified by the --python argument available to the +virtualenv. For example, this makes readline and sqlite3 available +when a wrapped python is specified. If no --python argument is passed, +it will only add the path to the python used when building +`virtualenv`, which is the unwrapped python, so sqlite3 won't be +available. + + +diff --git a/virtualenv.py b/virtualenv.py +index bcf3225..3530997 100755 +--- a/virtualenv.py ++++ b/virtualenv.py +@@ -1163,20 +1163,7 @@ def path_locations(home_dir, dry_run=False): + + + def change_prefix(filename, dst_prefix): +- prefixes = [sys.prefix] +- +- if IS_DARWIN: +- prefixes.extend( +- ( +- os.path.join("/Library/Python", VERSION, "site-packages"), +- os.path.join(sys.prefix, "Extras", "lib", "python"), +- os.path.join("~", "Library", "Python", VERSION, "site-packages"), +- # Python 2.6 no-frameworks +- os.path.join("~", ".local", "lib", "python", VERSION, "site-packages"), +- # System Python 2.7 on OSX Mountain Lion +- os.path.join("~", "Library", "Python", VERSION, "lib", "python", "site-packages"), +- ) +- ) ++ prefixes = ["/nix/store", sys.prefix] + + if hasattr(sys, "real_prefix"): + prefixes.append(sys.real_prefix) +@@ -1199,6 +1186,8 @@ def change_prefix(filename, dst_prefix): + if src_prefix != os.sep: # sys.prefix == "/" + assert relative_path[0] == os.sep + relative_path = relative_path[1:] ++ if src_prefix == "/nix/store": ++ relative_path = "/".join(relative_path.split("/")[1:]) + return join(dst_prefix, relative_path) + assert False, "Filename {} does not start with any of these prefixes: {}".format(filename, prefixes) + +@@ -1375,6 +1364,11 @@ def install_python(home_dir, lib_dir, inc_dir, bin_dir, site_packages, clear, sy + site_filename_dst = change_prefix(site_filename, home_dir) + site_dir = os.path.dirname(site_filename_dst) + writefile(site_filename_dst, SITE_PY) ++ wrapper_path = join(prefix, "lib", PY_VERSION, "site-packages") ++ writefile( ++ join(site_dir, 'sitecustomize.py',), ++ "import sys; sys.path.append('%s')" % wrapper_path ++ ) + writefile(join(site_dir, "orig-prefix.txt"), prefix) + site_packages_filename = join(site_dir, "no-global-site-packages.txt") + if not site_packages: |
