每当我在Octave中使用help命令时，我都会收到以下错误：
octave 1:> help plot
error: system: unable to start subprocess for '"makeinfo --no-headers --no-warn --force --no-validate --output=- C:\Users\shashank\AppData\Local\Temp\octave-help-rqFGAY"'
error: called from __makeinfo__ at line 140 column 20 help at line 102 column 22
如何纠正它。
octave:2> help help
error: system: unable to start subprocess for '"makeinfo --no-headers --no-warn --force --no-validate --output=- C:\Users\shashank\AppData\Local\Temp\octave-help-U1Yzip"'
error: called from __makeinfo__ at line 140 column 20 help at line 102 column 22
如何纠正？
