Solve the following python programming problem given the following code:
def build_js() : 
    print ('Building BokehJS... ', end = '') 
    sys.stdout.flush () 
    os.chdir ('bokehjs') 
    if (sys.platform != 'win32') : 
        cmd = [join ('node_modules', '.bin', 'gulp'), 'build'] 
else : 
        cmd = [join ('node_modules', '.bin', 'gulp.cmd'), 'build'] 
t0 = time.time () 
    try : 
        proc = subprocess.Popen (cmd, stdout = subprocess.PIPE, stderr = subprocess.PIPE) 
except OSError as e : 
        print ((BUILD_EXEC_FAIL_MSG % (cmd, e))) 
        sys.exit (1) 
finally : 
        os.chdir ('..') 
result = proc.wait () 
    t1 = time.time () 
    if (result != 0) : 
        indented_msg = '' 
        outmsg = proc.stdout.read ().decode ('ascii', errors = 'ignore') 
        outmsg = '

        errmsg = proc.stderr.read ().decode ('ascii', errors = 'ignore') 
        errmsg = '
'.join ([('    ' + x) for x in errmsg.split ('
')]) 
        print ((BUILD_FAIL_MSG % (red (outmsg), red (errmsg)))) 
        sys.exit (1) 
indented_msg = '' 
    msg = proc.stdout.read ().decode ('ascii', errors = 'ignore') 
    pat = re.compile ('(\\[.*\\]) (.*)', re.DOTALL) 
    for line in msg.strip ().split ('

        m = pat.match (line) 
        if (not m) : 
            continue 
(stamp, txt) = m.groups () 
        indented_msg += (((('   ' + dim (green (stamp))) + ' ') + dim (txt)) + '

msg = '

    print ((BUILD_SUCCESS_MSG % e)) 
    print (('Build time: %s' % bright (yellow (('%0.1f seconds' % (t1 - t0))))))

        def size(* path) : 
            return (os.stat (join ('bokehjs', 'build', * path)).st_size / (2 ** 10)) 
print (('  - bokeh.js              : %6.1f KB' % size ('js', 'bokeh.js'))) 
        print (('  - bokeh.css             : %6.1f KB' % size ('css', 'bokeh.css'))) 
        print (('  - bokeh.min.js          : %6.1f KB' % size ('js', 'bokeh.min.js'))) 
        print (('  - bokeh.min.css         : %6.1f...
