PyInstaller 无法在 linux 中构建 'Firebase Firestore python file'

Question

当我试图构建一个 linux 可执行文件时它构建成功但是当我尝试运行可执行文件时它显示这个错误

Traceback (most recent call last):
  File "pkgutil.py", line 637, in get_data
  File "/home/user/.local/lib/python3.8/site-packages/PyInstaller/loader/pyimod03_importers.py", line 341, in get_data

python 文件 main.py

import firebase_admin
from firebase_admin import credentials
from firebase_admin import db, firestore

# firebase app setup
cred = credentials.Certificate({ 
"type": "service_account",
"project_id": "project-216t8",

})
firebase_admin.initialize_app(cred)


def fetch_data():
    doc_ref = DocCollection_ref   
    docs= doc_ref.get()
    if docs.exists:
         docs = docs.to_dict()   
         print(f'Document data: {docs.to_dict()}')
    else:
     print(u'No such document!')

fetch_data()

这个解决方案对我有用。

您将需要为依赖于 setuptools' get_distribution() 的包创建一个 pyinstaller 挂钩，以获取有关包的元数据信息。

在某个hooks 目录中创建一个hook 文件。文件名应为 hook-<modulename>.py 以便 pyinstaller 正确找到它（即 hook-gcloud.py）。

解决方案： 创建两个 hook 文件：

勾-gcloud.py
勾-grpc.py

在hook-gcloud.py中写下代码并保存：

from PyInstaller.utils.hooks import copy_metadata
datas = copy_metadata('gcloud')

在hook-grpc.py中写下代码并保存：

from PyInstaller.utils.hooks import collect_data_files
datas = collect_data_files ( 'grpc' )

现在将这两个文件复制并粘贴到 /lib/python3.8/site-packages/PyInstaller/hooks/ 目录。
