在augeas中发生parse_failed错误，为什么会出现此错误以及如何解决此问题？

Question

我想编辑文件＆＃34; myfileDB.properties＆＃34;使用augeas。所以使用了Properties.lns。 但它犯了错误＆＃34; parse_failed＆＃34;而且有些时间＆＃34; parse_skel_failed＆＃34;。解释此错误的根本原因并解决此问题。

 augtool> print /augeas/files/root/yog/myfileDB.properties/error/
 /augeas/files/root/yog/myfileDB.properties/error = "parse_failed"
 /augeas/files/root/yog/myfileDB.properties/error/pos = "17835"
 /augeas/files/root/yog/myfileDB.properties/error/line = "318"
 /augeas/files/root/yog/myfileDB.properties/error/char = "0"
 /augeas/files/root/yog/myfileDB.properties/error/lens = "/usr/share  /augeas/lenses/dist/properties.aug:50.25-.100:"
 /augeas/files/root/yog/myfileDB.properties/error/message = "Iterated lens matched less than it should"

   /augeas/files/root/yog/myfileDB.properties/error = "parse_skel_failed"
   /augeas/files/root/yog/myfileDB.properties/error/pos = "4844943"
   /augeas/files/root/yog/myfileDB.properties/error/line = "53707"
   /augeas/files/root/yog/myfileDB.properties/error/char = "0"
   /augeas/files/root/yog/myfileDB.properties/error/lens = "/usr/share/augeas/lenses/dist/simplevars.aug:34.10-.46:"
   /augeas/files/root/yog/myfileDB.properties/error/message = "Iterated lens matched less than it should"
