简介

在本文中，我们将介绍如何使用命令行工具在你的设备上安装OpenHarmony操作系统。OpenHarmony是一个开源的、面向物联网（IoT）设备的操作系统，它提供了一套全面的开发框架，使得开发者可以更容易地创建和部署IoT应用。

在本次安装中，使用的电脑是基于Ubuntu22的物理机器，按照官方文档的说明，优先推荐的方式是使用 DevEco Studio 进行开发，这种方式使用Windows 做前端，Linux 虚拟机作为编译后端，对于Linux 不熟悉的新手来说比较友好，与此同时也限制了使用的环境，例如 DevEco Device Tool 目前无法在Ubuntu22 上安装成功，因为 Ubuntu22 中默认的 Python 版本是3.10，Python版本不匹配，我尝试修改 DevEco Device Tool 中的部分文件并跳过完整性检查，依然无法安装。

相比使用GUI的方式，我更习惯使用命令行进行编译，简单高效，且灵活度更高，Linux有很多的发行版本，Ubuntu 在国内普通用户使用的最多的，同时也是最受欢迎的版本，但并不是每一个人都会使用Ubuntu，想要再 Ubuntu22 或者其他Linux 系统上编译，这应该是唯一的选择，由用户自己来解决依赖的缺失问题。

安装工具链

默认情况下，Ubuntu中使用的脚本解释器是dash（终端输入ls -l /bin/sh查看链接文件指向的位置），输入如下指令选择No，需要将其替换为bash

sudo dpkg-reconfigure dash

使用如下apt-get命令安装后续操作所需的库和工具：

sudo apt-get update && sudo apt-get install binutils binutils-dev git git-lfs gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib gcc-arm-linux-gnueabi libc6-dev-i386 libc6-dev-amd64 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z1-dev ccache libgl1-mesa-dev libxml2-utils xsltproc unzip m4 bc gnutls-bin python3.10 python3-pip ruby genext2fs device-tree-compiler make libffi-dev e2fsprogs pkg-config perl openssl libssl-dev libelf-dev libdwarf-dev u-boot-tools mtd-utils cpio doxygen liblz4-tool openjdk-8-jre gcc g++ texinfo dosfstools mtools default-jre default-jdk libncurses5 apt-utils wget scons python3.10-distutils tar rsync git-core libxml2-dev lib32z-dev grsync xxd libglib2.0-dev libpixman-1-dev kmod jfsutils reiserfsprogs xfsprogs squashfs-tools pcmciautils quota ppp libtinfo-dev libtinfo5 libncurses5-dev libncursesw5 libstdc++6 gcc-arm-none-eabi vim ssh locales libxinerama-dev libxcursor-dev libxrandr-dev libxi-dev git git-lfs

将Python3.10设置为Python与Python3的默认版本

which python3.10                                    # 查看python3.10的位置

sudo update-alternatives --install /usr/bin/python python {Python 3.10 路径} 1
sudo update-alternatives --install /usr/bin/python3 python3 {Python 3.10 路径} 1

获取gitee源码

首先需要下载gitee的repo工具:

curl https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 -o repo 
chmod a+x repo
sudo mv repo /usr/bin/
pip3 install -i https://repo.huaweicloud.com/repository/pypi/simple requests

OpenHarmony主干代码获取：

repo init -u https://gitee.com/openharmony/manifest.git -b master --no-repo-verify
repo sync -c
repo forall -c 'git lfs pull'

在源码根目录下执行prebuilts脚本，安装编译器及二进制工具:

bash build/prebuilts_download.sh

安装编译工具

在源码根目录运行如下命令安装hb并更新至最新版本:

python3 -m pip install --user build/hb

设置环境变量:

echo "export PATH=~/.local/bin:\$PATH" >> ~/.bashrc
source ~/.bashrc

按照官方的说法，在源码目录执行"hb help"，界面打印以下信息即表示安装成功：

[OHOS INFO] ----------------------------------------------------------------------------------------------------

...

下面是我尝试编译时遇到的问题，找不到Mapping

[OHOS ERROR] Traceback (most recent call last):

[OHOS ERROR]

这是由于Python3.10中collections中已经不再包含Mapping，需要将 /home/lhq/.local/lib/python3.10/site-packages/prompt_toolkit/styles/from_dict.py 中的第9行进行替换：

from collections import Mapping      # 原有代码
from collections.abc import Mapping  # 替换后的代码

编译测试

设置编译路径并选择需要编译的目标

hb set

输入后系统类型选择 small
目标板选择 qemu_small_system_demo

编译

hb build

输出如下信息即代表编译成功
