Conan installation of ORCA fails: Unable to connect to conan-center=https://conan.bintray.com about gporca HOT 8 CLOSED

Here's my progress so far. Hypothesis 1: I'm using the wrong version of conan.

I noticed that conan --version was causing an error. I was on 1.2.3.

Partial solution was to brew uninstall conan and then pip install conan

Now conan --version says 1.3.3

cd depends
./configure
make
make install_local
cd ..

The error for installing orca changes...

ERROR: HTTPSConnectionPool(host='conan.bintray.com', port=443): Max retries exceeded with url: /v1/conans/orca/v2.59.0/gpdb/stable/download_urls (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')],)",),))

This is where it should be looking: https://api.bintray.com/conan/greenplum-db/gpdb-oss

To configure Conan client to work with Bintray, you will need to add Bintray repository to the list of remotes. To add Bintray conan repository, use the following command:
conan remote add <REMOTE> https://api.bintray.com/conan/conan/conan-center 
And replace <REMOTE> with a name that identifies the repository (for example: "my-conan-repo"). 

To login use the conan user command:
conan user -p <APIKEY> -r <REMOTE> <USERNAME>
And provide your Bintray username and API key.

It looks like it's still looking in the right location based on the output above:

CONAN_USER_HOME=/Users/pivotal/workspace/gpdb/depends conan remote add gpdb-oss https://api.bintray.com/conan/greenplum-db/gpdb-oss;
...

Now, do you solve the problem? I have the same error when I issue the make command.

Hi @dayuebai
Could you please provide the conan version on your system conan --version ?
Also what is the exact error you see when you run make ?

from gporca.

Previously with gpdb latest version (5.10.2), after I run make, error message:

ERROR: orca/v2.57.0@gpdb/stable: Error in build_requirements() method, line 35
if int(vers.split("."[0]) < 3: TypeError: a bytes-like object is required, not str
make: *** [orca] Error 1

Then I tried the solution above by brew uninstall conan and pip install conan.
And I try installing gpdb 5.5.0

Now, my conan version: Conan version 1.6.1

After I run make, I get a new error message:

from gporca.

It looks like I got the same new error as mentioned in the solution above.

By the way, I use mac os high sierra.

I create a new issue related to the problem stated above under gpdb Github repository. For users who have similar problem on macOS, please refer to the new issue: greenplum-db/gpdb#5579
