Q1: Installation of the DolphinDB Python API failed; Import of the dolphindb package failed even though it is successfully installed.
It is recommended to install the .whl package (again) by following the steps below:
(1) Search for the dolphindb wheel that runs on your current operating system (e.g., Linux ARM, Mac ARM, etc.) on PyPI. Download the wheel (.whl file) to your local system. (2) Enter the following command in the terminal:
pip debug --verboseThe Compatible tags section indicates which distributions are compatible with your system.
(3) Rename the downloaded dolphindb wheel according to the compatibility tags. For example, the file name for Mac(x86_64) is "dolphindb-1.30.19.2-cp37-cp37m-macosx_10_16_x86_64.whl". If the compatibility tags show that the system version supported by pip is 10.13, then replace the "10_16" in the original filename with "10_13".
(4) Install the renamed wheel.
If the installation or import still fails, please post your question on StackOverflow with the "dolphindb" tag. We will get back to you soon.
