python - 需要帮助使用 pip 安装特定的 python 包

Question

我看到了与我的问题相关的问题，但这些答案对我不起作用。我正在尝试安装 xgboost 包，但出现此错误:

*No files/directories in C:\Users\Fatemeh\AppData\Local\Temp\pip-build-57cpr7io\xgboost\pip-egg-info (from PKG-INFO)*

我已经尝试了几乎所有选项，例如--no-cache-dir、--no-clean，但都出现了同样的错误。

如果你能帮我解决这个问题，我将不胜感激。我尝试从 Github 安装并尝试其他方法(使用 cmd 和 setup.py 脚本)，但他们没有安装整个包，并且一些 xgboost 命令不起作用。

我对使用 pip 安装其他软件包没有任何问题，xgboost 是唯一一个我在安装时遇到问题的软件包。

这是我使用的脚本以及我得到的输出(我已经从所有链接中删除了 https://):

Answer 1

我觉得可以

1. 首先从给定的链接下载 Wheel 文件 xgboost 0.90

2. 然后通过键入以下命令从下载文件夹安装此库

    python -m pip install downloads/package-name.whl

将包名替换为 wheel 文件名
