ubuntu-20.04.3 hb 安装失败

master3@master3-pc:~$ hb -h
Traceback (most recent call last):

解决方案：

首先，安装之后还需要在环境变量中配置才会生效；

其次，可能和hb的版本有关，你可以先当前的hb先卸载，然后在源码根目录下重新安装

# 首先需要cd到源码根目录
pip3 uninstall ohos-build
pip3 install build/lite

master3@master3-pc:~$
master3@master3-pc:~$ pip3 uninstall ohos-build
Found existing installation: ohos-build 0.4.6

Proceed (Y/n)? y
