PyInstaller无法在linux中构建“Firebase Firestore python文件”

Question

当我尝试构建linux可执行文件时，它会成功构建，但当我尝试运行可执行文件时，它会显示此错误

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效

您需要为依赖于setuptools'get_distribution（）的包创建pyinstaller钩子，以获取有关包的元数据信息

在一些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： 创建两个钩子文件：

• hook-gcloud.py

• hook-grpc.py

在hook gcloud.py中编写以下代码并保存：

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

在hook grpc.py中编写以下代码并保存：

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
