Question

我尝试将应用程序部署到Heroku。应用程序仅在更改引擎版本后才能成功部署。如果我尝试部署而没有修改＆＃34;引擎＆＃34;部分，部署失败并显示以下错误：

remote:        ERROR in ./resources/assets/sass/app.scss
remote:        Module build failed: ModuleBuildError: Module build failed: Error: ENOENT: no such file or directory, scandir '/tmp/build_7b88e5ab3110a2273bdb09b2d4f7c673/node_modules/node-sass/vendor'

这是我的package.json

  }
}

也许你有任何解决方案，除了更改引擎版本？

Answer 1

我在Heroku上找到了解决方案 - 已禁用的节点模块缓存：

#include <PS2X_lib.h>  //for v1.6
#include "Joystick.h"
#include<SoftwareSerial.h>


Joystick_ Joystick(JOYSTICK_DEFAULT_REPORT_ID, JOYSTICK_TYPE_GAMEPAD,
    12, 2, // Button Count, Hat Switch Count
    true, true, true, // X and Y, but no Z Axis
    false, false, true, // No Rx, Ry, or Rz
    false, false, // No rudder or throttle
    false, false, false);  // No accelerator, brake, or steering

#define PS2_DAT        3  //14    
#define PS2_CMD        2  //15
#define PS2_SEL        12  //16
#define PS2_CLK        13  //17

//#define pressures true
#define pressures false
//#define rumble true
#define rumble false

const bool testAutoSendMode = false;
SoftwareSerial BTSerial(11, 10);
PS2X ps2x;

int error = 0;
byte type = 0;
byte vibrate = 0;

void setup() {
  SoftwareSerial BTSerial(11, 10);
  BTSerial.begin(57600);
  Serial.begin(57600);
  delay(300);
  Joystick.begin();
  //setup pins and settings: GamePad(clock, command, attention, data, Pressures?, Rumble?) check for error
  error = ps2x.config_gamepad(PS2_CLK, PS2_CMD, PS2_SEL, PS2_DAT, true, false);
  type = ps2x.readType();
  Joystick.setXAxisRange(0, 255);
  Joystick.setZAxisRange(0, 255);
  Joystick.setYAxisRange(0, 255);
  Joystick.setRzAxisRange(0, 255);
}

byte ReadOneByte() {
  int ByteRead;
  while (!BTSerial.available());
  ByteRead = BTSerial.read();
  return ByteRead;
}

void loop() {
  ReadOneByte() ;
  // Always be getting fresh data
  if (error == 1) //skip loop if no controller found
    return;
  error = ps2x.config_gamepad(PS2_CLK, PS2_CMD, PS2_SEL, PS2_DAT, pressures, rumble);
  ps2x.read_gamepad(false, 0);
  Joystick.setButton(0, ps2x.Button(PSB_TRIANGLE));
  Joystick.setButton(1, ps2x.Button(PSB_CIRCLE));
  Joystick.setButton(2, ps2x.Button(PSB_CROSS));
  Joystick.setButton(3, ps2x.Button(PSB_SQUARE));
  Joystick.setButton(4, ps2x.Button(PSB_L2));
  Joystick.setButton(5, ps2x.Button(PSB_R2));
  Joystick.setButton(6, ps2x.Button(PSB_L1));
  Joystick.setButton(7, ps2x.Button(PSB_R1));
  Joystick.setButton(8, ps2x.Button(PSB_SELECT));
  Joystick.setButton(9, ps2x.Button(PSB_START));
  Joystick.setButton(10, ps2x.Button(PSB_L3));
  Joystick.setButton(11, ps2x.Button(PSB_R3));
  Joystick.setXAxis(ps2x.Analog(PSS_LX));
  Joystick.setYAxis(ps2x.Analog(PSS_LY));
  Joystick.setZAxis(ps2x.Analog(PSS_RY));
  Joystick.setRzAxis(ps2x.Analog(PSS_RX));
  if (ps2x.Button(PSB_PAD_UP)) { //will be TRUE as long as button is pressed
    Joystick.setYAxis(0);
  }
  if (ps2x.Button(PSB_PAD_RIGHT)) {
    Joystick.setXAxis(255);
  }
  if (ps2x.Button(PSB_PAD_LEFT)) {
    Joystick.setXAxis(0);
  }
  if (ps2x.Button(PSB_PAD_DOWN)) {
    Joystick.setYAxis(255);
  }
}

Answer 2

这是解决此问题的解决方案：

pandas.cut

或者，对于"scripts": { "heroku-postbuild": "yarn add --force node-sass" }：

npm
