php - Laravel 到 Python RuntimeError：无法确定主目录

问题描述

在我的 Laravel (php) 产品中，我们调用了 python 脚本。当我在命令提示符下运行此脚本时，它工作正常。但是从 Laravel 控制器它引发了一个错误。

错误输出：

Traceback (most recent call last):

    raise RuntimeError("Can't determine home directory")
RuntimeError: Can't determine home directory
"""

我们正在使用 laravel 进程特性来执行这个 python 脚本。

请让我知道如何解决此问题。

解决方案

我遇到了和你一样的问题，我可以通过手动设置变量来解决它，因为问题是

os.environ['HOME']

没有，这导致了问题

因此，您可以使用此代码手动设置它

os.environ['HOME'] = 'C:/Python'

设置时检查你使用的是“/”而不是“\”，否则会报错。

它解决了我的问题。我也在使用 Apache 并调用 Python 脚本，并确保您的代码在脚本顶部有 python 的路径

#!C:\Python\python.exe
