无法在firebase功能中使用pandas

Question

我想在我的 google cloud-firebase 功能中使用 pandas，我使用以下方法安装它：

python3 pip install pandas

并将其导入到我的函数中：

import pandas as pd

但是，在 firebase 模拟器中我遇到了这个错误：

[2023-09-26 00:04:58,056] ERROR in app: Exception on /__/functions.yaml [GET]

import pandas as pd ModuleNotFoundError: No module named 'pandas' 

我检查了pandas是否安装正确，在jupyter笔记本中测试了这个简单的代码：

import pandas as pd
df = pd.DataFrame(
    {
            "Name": [
                "Braund, Mr. Owen Harris",
                "Allen, Mr. William Henry",
                "Bonnell, Miss. Elizabeth",
            ],
            "Age": [22, 35, 58],
            "Sex": ["male", "male", "female"],
        }
)
print(df.head(2))

看起来还不错：

还在“requirements.txt”的依赖中添加pandas，但错误仍然相同

# version 1, didn't work
firebase_functions~=0.1.0
pandas~=2.0.0

# version 2, also didn't work
firebase_functions~=0.1.0
pandas

我用谷歌搜索了几个小时，但找不到我丢失的内容或我应该做什么来修复它。

请有人寄给我一个救生员。

谢谢！！

Answer 1

安装步骤。

首先在终端中进入 de 文件夹

cd functions/venv/Scripts

现在输入您要安装的库

python.exe -m pip install pandas

我录制了一个视频可以帮助您，因为这是相同的过程。就我而言，效果很好。确保将它们也添加到requirement.txt中
