我有一个Python包,使用PyInstaller将其打包为单个可执行文件。

我使用
logging
模块与基于文件的配置相结合。为了实现集中化、基于云的日志记录,我决定使用模块loggly-python-handler和python-json-logger将日志信息发送到Loggly。后者将日志消息转换为JSON格式,前者使用HTTP(S)调用发送(JSON)日志消息到Loggly。以下是我的日志配置摘录(当然,实际的
TOKEN
值已被删除):[handler_loggly]
class=loggly.handlers.HTTPSHandler
formatter=json
args=('https://logs-01.loggly.com/inputs/TOKEN/tag/test','POST')
level=CRITICAL
[formatter_json]
format= %(name)s %(asctime)s %(filename)s %(created)f %(funcName)s %(levelno)s %(lineno)d %(msecs)d %(levelname)s %(message)s
class=pythonjsonlogger.jsonlogger.JsonFormatter
当在已安装Python及必要库的计算机上运行时,此方法可正常工作。然而,由PyInstaller生成的可执行文件似乎缺少所需的日志记录模块(因为它们没有被引用到源代码中,只在日志配置中被调用)。
运行可执行文件时出现错误输出:
Traceback (most recent call last):
File "c:\python35\lib\logging\config.py", line 98, in _resolve
AttributeError: module 'pythonjsonlogger' has no attribute 'jsonlogger'
During handling of the above exception, another exception occurred:

我尝试使用 PyInstaller 的隐藏导入功能来引用这两个模块:
pyinstaller \
--log-level=DEBUG \
--onefile \
--hidden-import=loggly \
--hidden-import=pythonjsonlogger main.py
日志文件输出:
3463 DEBUG: Hidden import: loggly
3463 INFO: Analyzing hidden import 'loggly'
3463 DEBUG: Hidden import: pythonjsonlogger
3478 INFO: Analyzing hidden import 'pythonjsonlogger'
尝试2
在PyInstaller的spec文件中指定导入项(代码片段如下):
a = Analysis(['main.py'],
pathex=['C:\\Dev\\pyWebiExport'],
binaries=None,
datas=None,
hiddenimports=['loggly.handlers.*', 'pythonjsonlogger.jsonlogger.*'],
hookspath=None,
…
日志文件输出:
3510 DEBUG: Hidden import: loggly.handlers.*
3510 INFO: Analyzing hidden import 'loggly.handlers.*'
5694 ERROR: Hidden import 'loggly.handlers.*' not found
5694 DEBUG: Hidden import: pythonjsonlogger.jsonlogger.*
