Uploading code to ESP

Development Tools Uploading
1

Hello! I have ESP8266 Lolin NodeMCU board, and I use PlatformIO to upload the code. I faced to a problem with uploading. Also it doesn't has boot button - only flash and rst. Can someone help me?

This is platform.ini code:

[env:nodemcuv2]

platform = espressif8266

board = nodemcuv2

framework = arduino

monitor_speed = 9600

upload_port = /dev/ttyUSB0

Here's the message:
