在输入pip install sklearn后，出现如下提示：
python
pip install sklearnCollecting sklearn Using cached sklearn-0.0.post12.tar.gz (2.6 kB) Installing build dependencies ... done Getting requirements to build wheel ... error error: subprocess-exited-with-error × Getting requirements to build wheel did not run successfully.
│ exit code: 1 ╰─> [15 lines of output] The 'sklearn' PyPI package is deprecated, use 'scikit-learn' rather than 'sklearn' for pip commands. Here is how to fix this error in the main use cases: - use 'pip install scikit-learn' rather than 'pip install sklearn' - replace 'sklearn' by 'scikit-learn' in your pip requirements files (requirements.txt, setup.py, setup.cfg, Pipfile, etc ...) - if the 'sklearn' package is used by one of your dependencies, it would be great if you take some time to track which package uses 'sklearn' instead of 'scikit-learn' and report it to their issue tracker - as a last resort, set the environment variable SKLEARN_ALLOW_DEPRECATED_SKLEARN_PACKAGE_INSTALL=True to avoid this error More information is available at https://github.com/scikit-learn/sklearn-pypi-package [end of output]
在翻译原文后，得出：
收集 sklearn
正在使用缓存的 sklearn-0.0.post12.tar.gz (2.6 kB)
正在安装构建依赖项... 完成
获取构建轮子的需求... 出错
错误：子进程退出并出现错误
× 获取构建轮子的需求未成功运行。
│ 退出代码：1
╰─> [15 行输出]
PyPI 上的 'sklearn' 包已被弃用，请使用 'scikit-learn'
而不是 'sklearn' 来执行 pip 命令。
便使用如下代码继续尝试：
python
pip install scikit-learn结束！！！
