我使用 pyqt5 行编辑框作为输入框。我想从输入框中获取输入并将其从字符串转换为十六进制以发送到串行捕获。例如我这样做了但没有成功：
a = hex(self.slave1.text())
b = hex(self.function1.text())
c = hex(self.address_msb1.text())
d = hex(self.address_lsb1.text())
e = hex(self.register_msb1.text())
f = hex(self.register_lsb1.text())
g = hex(self.crc_lsb1.text())
h = hex(self.crc_msb1.text())
hexConvert = [a,b,c,d,e,f,g,h]
想象：
a = "01"
b = "03"
c = "00"
d = "0A"
e = "00"
f = "04"
g = "64"
h = "0B"
我的预期输出是
[0x01, 0x03, 0x00, 0x0A, 0x04, 0x64, 0x0B]
我有一个使用 ruby 版本 2.6.6 的现有项目。但我的机器ruby版本是3.0.2。因此，当我尝试在我的计算机上运行我的项目时，它会显示此错误。
Your Ruby version is 3.0.2, but your Gemfile specified 2.6.6
所以我也尝试使用 rbenv 环境安装 ruby 2.6.6
rbenv install 2.6.6
