Python testing.postgresql 錯誤：initdb 需要程序“postgres”

Question

我們有一些使用 testing.posgresql 的 python 單元測試，但是我無法讓它們在我的機器（Windows 10）上為我工作。 我收到有關 initdb 需要 postgresql 但無法在同一目錄中找到它的上述錯誤。 我可以確認它們都在 PostgresSQL 安裝的 bin 目錄中，並且在該目錄中嘗試直接運行 initdb 時出現相同的錯誤。 此安裝的 bin 和 lib 目錄也在我的路徑中，並且在運行which initdb或which postgres時我得到了正確的位置，我嘗試了一些事情，包括在具有類似問題但沒有任何效果的線程中提出的所有解決方案，它適用於 macOS 和我們的 github 工作流程。 我安裝了 PostgresSQL 14 並且正在使用 cygwin（盡管在 windows cmd 中運行時會出現完全相同的錯誤），感謝您的幫助。

Output 從 Postgres 安裝的 bin 目錄運行 initdb 時：

$ ./initdb -D example
The system cannot find the path specified.
child process exited with exit code 1
initdb: error: The program "postgres" is needed by initdb but was not found in the
same directory as "C:/Program Files/PostgreSQL/14/bin/initdb.exe".
Check your installation.

但是一個簡單的 ls 顯示 postgres.exe 確實存在：

我無法評論您的帖子：但是我一直在嘗試在我的服務器上安裝 PostgreSQL 14，該服務器已經在運行 PostgreSQL 12。我看到與“radEA2DE.bat”相關的相同錯誤。 這是我的安裝日志中的相關代碼塊：

but was not the same version as initdb.
Check your installation.

我希望這有助於提供線索。
