aos-cube已经安装成功,但是还是无法运行aos指令(找不到aos)
这种情况请安装如下操作进行确认:
第一步:
可以试试重启终端或者vscode,然后再运行aos指令。如果还是不行的话,请参考第二步。
第二步:
- 请确认aos-cube安装在哪个目录:
win10:/d/workspace/github/AliOS-Things$ python -m site
sys.path = [
'D:\\workspace\\github\\AliOS-Things',
'C:\\windows\\SYSTEM32\\python27.zip',
'C:\\Python27\\DLLs',
'C:\\Python27\\lib',
'C:\\Python27\\lib\\plat-win',
'C:\\Python27\\lib\\lib-tk',
'C:\\Python27',
'C:\\Users\\xxxx\\AppData\\Roaming\\Python\\Python27\\site-packages',
'C:\\Python27\\lib\\site-packages',
]
USER_BASE: 'C:\\Users\\xxxx\\AppData\\Roaming\\Python' (exists)
USER_SITE: 'C:\\Users\\xxxx\\AppData\\Roaming\\Python\\Python27\\site-packages' (exists)
ENABLE_USER_SITE: True
其中USER_BASE
就是python用户安装目录,查看该用户安装目录下的Scripts
中是否存在aos指令,如果存在的话,把该目录(C:\Users\chenan.xxw\AppData\Roaming\Python\Scripts
)添加到Path环境变量中即可。
如果还是有问题的话,请提问题到github issues,或者可以参考使用我们提供的docker镜像。
aos-cube升级到新版本无法正常工作
aos-cube升级到0.3.x版本,运行aos提示“from aos.main import main”失败,本地Python模块路径未更新,可尝试先卸载再安装:
# 首先卸载已安装的aos-cube
$ pip uninstall aos-cube
# 重新安装aos-cube
$ pip install aos-cube
linux系统上串口、usb没有权限
Linux 操作串口及 j-link 会有root权限要求,尤其在使用 AliOS Studio时候。可以复制60-openocd.rules(来自 Arduino
github project)文件到 /etc/udev/rules.d
目录下,然后运行如下命令生效:
sudo udevadm control --reload-rules
或者你也可以手动对串口及 j-link 的权限做配置:
$ sudo usermod -a -G dialout $(whoami)
,添加当前用户到 dialout 组,提供直接使用串口能力。
$lsubs
找到 j-link 厂商ID。如:Bus 002 Device 008: ID 1366:0105 SEGGER
,厂商ID为1366,新建/etc/udev/rules.d/99-stlink-v2.rules
文件,在文件里面添加规则:SUBSYSTEM=="usb", ATTR{idVendor}=="1366", MODE="666", GROUP="plugdev"
。
配置操作串口及 j-link权限后,重启系统生效。

aos-cube 0.3.11之前版本只支持python2.7,当前环境如果是python3的话,运行aos-cube就会导致冲突,请更新aos-cube。

UnicodeDecoderError:‘utf8’ codec can't decode byte xxx in position xxx
文件路径里包含中文等其它特殊字符;或者源代码文件是非ascii和utf8编码的,且包含中文等特殊字符。
需要将AliOS-Things的代码放在不包含特殊字符的路径下,并且创建工程目录时,也需要确保路径中不包含特殊字符;
对于非ascii编码和utf8编码的文件,需要使用vs code等编辑器将其转为utf8编码。同时需要更新文中包含的特殊字符,否则会显示乱码。
