Windows Gitbash下pip22.3安装compressai遇subprocess-exited-with-error求助

问题背景 #

Windows系统，通过Gitbash执行命令，已将pip升级至22.3版本，执行pip install compressai时触发subprocess-exited-with-error错误。此前尝试降级pip无效，因compressai要求使用最新版本pip。

具体报错信息 #

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: subprocess-exited-with-error

解决方案 #

报错核心是源码包的manifest文件中包含了CI构建环境的绝对路径，导致本地构建失败，以下两种方法解决：

方法1：安装预编译wheel包（推荐，避免编译） #

• 强制pip使用预编译的二进制包执行安装：

  pip install --only-binary :all: compressai
  

• 如果上述命令找不到对应版本的wheel，可手动获取适配自身Python版本和系统的wheel文件，执行本地安装：

  pip install /path/to/compressai-xxx.whl
  

方法2：修改源码后本地编译安装 #

• 克隆compressai官方仓库到本地
• 进入仓库目录，找到并修改MANIFEST.in或相关配置文件，将其中的绝对路径/home/runner/work/CompressAI/CompressAI/替换为相对路径（直接保留compressai/cpp_exts/ops/ops.cpp这类相对路径即可）
• 执行本地安装：

  pip install .
