Arduino: error: {build.flash_flags}: No such file or directory

I tried to integrate travis-ci into my project.
.travis.yml

language: c
before_install:
  - "/sbin/start-stop-daemon --start --quiet --pidfile /tmp/custom_xvfb_1.pid --make-pidfile --background --exec /usr/bin/Xvfb -- :1 -ac -screen 0 1280x1024x16"
  - sleep 3
  - export DISPLAY=:1.0
  - wget http://downloads.arduino.cc/arduino-${IDE_VERSION}-linux64.tar.xz
  - tar xf arduino-${IDE_VERSION}-linux64.tar.xz
  - sudo mv arduino-${IDE_VERSION} /usr/local/share/arduino
  - sudo ln -s /usr/local/share/arduino/arduino /usr/local/bin/arduino

  matrix:
    - BOARD="esp8266:esp8266:generic" SOURCE="$PWD/srcs/ESP8266/ESP8266.ino"

During verifying the source code, i got this error xtensa-lx106-elf-g++: error: {build.flash_flags}: No such file or directory and the build process exited with 1 after that.
Could this problem related to the version of Arduino IDE (1.8.8) ?

Hello @thangktran, I'm having this exact same problem. How did you solve your issue?

Hello @chris24gutsch,
I checked the build log from Arduino IDE and found out that esp8266:esp8266:generic is not enough since lots of other parameters are missing. In my case i use: esp8266:esp8266:generic:xtal=80,vt=flash,exception=disabled,ResetMethod=ck,CrystalFreq=26,FlashFreq=40,FlashMode=dout,eesz=512K,led=2,ip=lm2f,dbg=Disabled,lvl=None____,wipe=none,baud=115200.

@thangktran,
That fixed it. You are an absolute life saver and I cannot thank you enough!
