注册码云账户，配置SSH公钥，配置Git，这些步骤以前做过，不再描述，可以看官方教程。
1 安装repo
curl https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 > /usr/local/bin/repo
chmod a+x /usr/local/bin/repo
pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple requests
2 下载源码
mkdir openharmony
cd openharmony
repo init -u https://gitee.com/openharmony/manifest.git -b master --no-repo-verify
repo sync -c -j2
我用1.0版本
repo init -u https://gitee.com/openharmony/manifest.git -b OpenHarmony-1.0
10分钟左右下完。1.64GB。
报错
- Mac拉取源码，报错
repo init -u https://gitee.com/openharmony/manifest.git -b master --no-repo-verify
Downloading Repo source from https://gitee.com/oschina/repo.git
fatal: Cannot get https://gitee.com/oschina/repo.git/clone.bundle
fatal: error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:777)
fatal: cloning the git-repo repository failed, will remove '.repo/repo'
原因是mac的python3.6使用自带的openssl，需要安装证书。
解：
open /Applications/Python\ 3.6/Install\ Certificates.command

- 用清华的repo会有一些错误，要改用gitee的repo。
