安装PyCaret时遭遇subprocess-exited-with-error报错求助

报错现象 #

执行!pip install pycaret时触发以下错误：

error: subprocess-exited-with-error
pip subprocess to install build dependencies did not run successfully.
exit code: 1
note: This error originates from a subprocess, and is likely not a problem with pip.
error: legacy-install-failure
Encountered error while trying to install package.
numpy
note: This is an issue with the package mentioned above, not pip.

解决方案 #

• 先升级pip、setuptools和wheel，确保构建工具为最新版本：

  !pip install --upgrade pip setuptools wheel
  

• 单独安装稳定兼容版本的numpy，再安装PyCaret：

  !pip install numpy==1.26.4
  !pip install pycaret
  

• 检查Python版本兼容性：PyCaret要求Python 3.8-3.11版本，若当前环境版本不在此范围，切换到符合要求的Python环境后再尝试安装。
• 若有conda环境，可优先用conda安装预编译的numpy包（避免构建问题），再安装PyCaret：

  !conda install numpy -y
  !pip install pycaret
