OpenHarmony轻量系统开发【2】源码下载和开发环境-开源基础软件社区-51CTO.COM

跟着上述链接安装OpenHarmony环境，执行到第四步：安装hb
在源码根目录下载运行如下命令安装hb

python3 -m pip install build/lite

(1) 问题

出现如下错误：

 （2） 找原因

Processing ./build/lite
  Preparing metadata (setup.py) ... error
  error: subprocess-exited-with-error
  
  × python setup.py egg_info did not run successfully.
  │ exit code: 1
  ╰─> [6 lines of output]
      Traceback (most recent call last):

        File "", line 34, in <module>
        File "/home/xx/OpenHarmony/code/master/master0729/build/lite/setup.py", line 22, in <module>
          from hb.__main__ import VERSION
      ImportError: cannot import name 'VERSION' from 'hb.__main__' (/home/xx/OpenHarmony/code/master/master0729/build/lite/hb/__main__.py)
      [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.

× Encountered error while generating package metadata.

 其中倒数第二句：

note: This is an issue with the package mentioned above, not pip.

表示不是pip的问题；

问题出在这里：

File "/home/xx/OpenHarmony/code/master/master0729/build/lite/setup.py", line 22, in <module>
          from hb.__main__ import VERSION
      ImportError: cannot import name 'VERSION' from 'hb.__main__' (/home/xx/OpenHarmony/code/master/master0729/build/lite/hb/__main__.py)

即：从gitee上 下载的源码，/build/lite/hb 目录下的__main__.py文件没有导入VERSION，而/build/lite/hb目录下setup.py有 

（3）解决问题

 于是选择直接去官网下载源码：OpenHarmony鸿蒙开源项目 | 鸿蒙学堂 (hmxt.org)

 

查看从官网下载下来的源码：

/build/lite/hb 目录下的__main__.py文件导入了VERSION

为了安全起见，我将官网下载下来的lite文件夹直接替换从gitee上下载的lite文件夹

之后，重新执行

python3 -m pip install build/lite

最后，成功了^ ^
