I also read the issue 35 & issue 179, but my settings and project did not have same problem, the error still existed.
I want to ask what should I do in next step?
Hope and thanks for your help.

How do you know you don't have the same problem?

What other Oracle software do you have on your machine?

How did you install node-oracledb - did you copy it from another machine?

@cjbj
Followed the issue 35, I checked my instant client directory, there has oci.dll.
And the issue 179 is caused by Unicode characters, all file in my testing directory is English character.

There has no other Oracle software in my computer.
I had tried to copy to my colleagues' computer, it still did not work.

I just tried to change the version of Node.js, Oracle Instant Client, Python, from 64 bit to 32 bit.
And then it work successfully.
Thanks for your response.
But I still confuse why the 64bit did not work.

From the not yet-obvious https://github.com/oracle/node-oracledb/blob/dev-2.0/INSTALL.md#troubleshooting

Does your Node.js architecture (32-bit or 64-bit) match the Oracle client library architecture? Run node -p 'process.arch' and compare with, for example, dumpbin /headers oci.dll (on Windows), file libclntsh.dylib (macOS) or file libclntsh.so.* (Linux).

But check you are looking at the right files.
