Firebird嵌入式安装问题:无法确定库 [英] Firebird embedded installation issue: library could not be determined

问题描述

我一直在编写一个打开Firebird数据库的小型Python应用程序.
为了实现这一目标，我使用了64位的Firebird嵌入式2.5.7.27050.使用Python连接到数据库文件时，出现以下错误:

I've been writing a small Python application that opens a Firebird database.
To achieve this goal I'm using Firebird embedded 2.5.7.27050, 64 bit.

Although, whenever I try to connect to the DB file with Python, I get the following error:

Traceback (most recent call last):
  File "C:\Matteo\CMakeR\initApp.py", line 36, in <module>
    connection = connectToDB(path)
  File "C:\Matteo\CMakeR\initApp.py", line 10, in connectToDB
    charset='WIN1252'
  File "C:\Program Files\Python36\lib\site-packages\fdb\fbcore.py", line 682, in connect
    load_api(fb_library_name)
  File "C:\Program Files\Python36\lib\site-packages\fdb\fbcore.py", line 181, in load_api
    setattr(sys.modules[__name__],'api',fbclient_API(fb_library_name))
  File "C:\Program Files\Python36\lib\site-packages\fdb\ibase.py", line 1398, in __init__
    raise Exception("The location of Firebird Client Library could not be determined.")
Exception: The location of Firebird Client Library could not be determined.
>>> 

似乎FB Client安装不正确.
但是我非常仔细地遵循doc文件夹中的安装指南.
这是我的应用程序文件夹:

It seems that the FB Client is not installed properly.
However I followed very carefully the installation guide inside the doc folder.
Here's my app folder:

推荐答案

谢谢大家帮助我解决了这个问题.
由于Arioch'The的建议，我终于找到了解决方案.

使用 Microsoft Process Monitor ，我能够检测到我的应用程序所在的文件夹在寻找客户端库.然后我注意到它们是在PATH环境变量中指定的文件夹.
因此，我将包含Python文件的文件夹添加到PATH变量中，一切终于解决了.

Thank you all for helping me solve this issue.
I finally found a solution thanks to Arioch 'The's suggestion.

Using Microsoft Process Monitor I was able to detect the folders where my app was looking for the client library. Then I noticed that they were the same folders specified in the PATH environment variable.
So I added the folder containing my Python file to the PATH variable and everything finally worked out.
