编译出现错误[OHOS ERROR] ohos-sdk build failed! You can try to use '--no-prebuilt-sdk' to skip the build of ohos-sdk. 请问是什么原因呢？

1. 下载代码，执行bash build/prebuilts_download.sh， 执行./build.sh --product-name rk3568 --ccache
2. 过程中提示： [OHOS INFO] The OHOS-SDK was not detected, so the SDK compilation will be prioritized automatically. You can also control whether to execute this process by using '--no-prebuilt-sdk' and '--prebuilt-sdk'.
3. 编译报错： [OHOS ERROR] ohos-sdk build failed! You can try to use '--no-prebuilt-sdk' to skip the build of ohos-sdk.

注：ubuntu 是 20.04

那句话意思就是编ohos-sdk 错了，你可以在命令里加 --no-prebuilt-sdk 这个跳过编sdk的步骤

回复 深开鸿_王石: 这是字面的意思，
实际上是一些编译环境工具没有安装成功，重新sudo install一遍就解决了
