meson-python：错误：安装pandas时找不到版本1.8.2或更新的ninja

Question

我正在通过 Namecheap 的共享主机部署我的 Django 应用，使用的是 cPanel 的终端。我的项目有一些依赖项在 requirements.txt 文件里。我在终端中安装这些依赖，但在安装 numpy 或 pandas 时遇到了错误。问题是我已经安装了 ninja 版本 1.11.1，而需要的版本是 1.8.2 或更新的版本，所以系统根本没有检测到 ninja。我也尝试过降级 ninja 的版本和不同的组合，但都没有成功。希望能得到一些帮助。

我尝试通过 GitHub 下载并克隆代码库，但仍然没有成功。

使用venv或virtualenv创建一个虚拟环境，这样可以把项目所需的库和系统自带的库分开，避免出现冲突：

python -m venv my_venv 

source my_venv/bin/activate  # Activate the virtual environment

在虚拟环境中安装pandas库：

pip install pandas

如果运行你的Django应用需要用到manage.py，记得在运行之前先激活虚拟环境：

source my_venv/bin/activate

接下来：

python manage.py runserver
