[Python-ideas] Policy for altering sys.path

[Thomas Güttler]

Hi,

for this case, the sys.path modification was solved like this:


-sys.path = glob.glob(os.path.join(WHEEL_DIR, "*.whl")) + sys.path
+sys.path[:] = glob.glob(os.path.join(WHEEL_DIR, "*.whl")) + sys.path

See https://github.com/pypa/pip/issues/2759
