aos-cube常见问题_FAQ_AliOS Things 文档_IoT物联网操作系统-阿里云

aos-cube已经安装成功，但是还是无法运行aos指令（找不到aos）

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：

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。

ModuleNotFoundError: No module named 'constant'

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。

请依次尝试以下方法：

更新scons：pip install scons -U

卸载scons然后重新安装：pip uninstall scons； pip install scons。

请使用虚拟环境安装aos-cube，参考链接：https://github.com/alibaba/AliOS-Things/wiki/AliOS-Things-Linux-Environment-Setup#安装python和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。
