Mac系统conda环境下Poetry无法安装psutil 5.9.4问题咨询

问题现象 #

在Mac系统的conda虚拟环境中，使用Poetry工具安装psutil包时，5.9.2和5.9.3版本均可正常完成安装，但尝试安装最新版本5.9.4时失败。

命令执行及报错详情 #

poetry add psutil=="5.9.2"

排查结论 #

该问题与部分已知的psutil安装问题不同，经详细日志排查，根源在于Poetry校验psutil 5.9.4的安装包时，发现多个包的SHA256校验值与预期不符，包括适配Mac ARM64的psutil-5.9.4-cp38-abi3-macosx_11_0_arm64.whl以及源码包psutil-5.9.4.tar.gz，导致所有适配当前环境的包都被跳过，最终抛出找不到安装候选的错误。

可行解决建议 #

• 清除Poetry缓存：缓存中的校验值可能过期，执行以下命令清除后重新尝试安装：

  poetry cache clear pypi --all
  

• 升级Poetry版本：旧版本Poetry可能存在校验逻辑问题，升级到最新版后重试：

  poetry self update
  

• 手动指定安装包：从PyPI下载对应版本的正确whl包，使用本地安装方式：

  poetry add ./psutil-5.9.4-cp38-abi3-macosx_11_0_arm64.whl
  

• 临时切换到pip安装：如果上述方法无效，可临时用pip在conda环境中安装，之后再同步到Poetry：

  pip install psutil==5.9.4
  poetry lock --no-update
