我是新来的:) 我买了带液晶屏的 Rapsberry Pico，我想在这个显示器上显示一些东西，但是当我导入 ssd1306 lib Thonny 时，给我发了一个问题“没有名为 ffi 的模块”，我不知道如何导入这个库。这是我的简单代码：

from machine import Pin, I2C
import ssd1306

i2c = I2C(scl=Pin(1), sda=Pin(0), freq=400000)
display = ssd1306.SSD1306_I2C(128, 64, i2c)
display.text("some text", 0, 0)
display.show()

我在 ofc 之前安装了 micropython-ssd1306 lib。

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "ssd1306.py", line 4, in <module>
  File "/lib/framebuf.py", line 2, in <module>
  File "/lib/usdl2.py", line 2, in <module>
ImportError: no module named 'ffi'

Im new here :)
I bought the Rapsberry Pico with the lcd screen, i want to display something on this display but when i import ssd1306 lib Thonny send me a problem "no module named ffi" i don't know how to import this lib.
Thats my simple code:

from machine import Pin, I2C
import ssd1306

i2c = I2C(scl=Pin(1), sda=Pin(0), freq=400000)
display = ssd1306.SSD1306_I2C(128, 64, i2c)
display.text("some text", 0, 0)
display.show()

I installed micropython-ssd1306 lib before ofc.

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "ssd1306.py", line 4, in <module>
  File "/lib/framebuf.py", line 2, in <module>
  File "/lib/usdl2.py", line 2, in <module>
ImportError: no module named 'ffi'
