Greenplum源码编译安装ORCA握手失败解决 - Caused by SSLError(SSLError("bad handshake: ...)

简介:

场景:

Greenplum在Mac上源码编译安装的时候,首先需要安装ORCA,安装ORCA的过程中,报错了。

报错内容:

ChrisdeMacBook-Pro:depends chris$ make
CONAN_USER_HOME=/Users/chris/git/gpdb/depends conan install --build=missing conanfile_orca.txt
orca/v2.56.0@gpdb/stable: Not found in local cache, looking in remotes...
orca/v2.56.0@gpdb/stable: Trying with 'conan-center'...
From cffi callback <function _verify_callback at 0x10f613a28>:
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/site-packages/OpenSSL/SSL.py", line 313, in wrapper
    _lib.X509_up_ref(x509)
AttributeError: 'module' object has no attribute 'X509_up_ref'
ERROR: HTTPSConnectionPool(host='conan.bintray.com', port=443): Max retries exceeded with url: /v1/conans/orca/v2.56.0/gpdb/stable/download_urls (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')],)",),))

Unable to connect to conan-center=https://conan.bintray.com
make: *** [orca] Error 1

报错原因:

复查前面的步骤,发现有一步python库冲突:

pyopenssl 17.5.0 has requirement cryptography>=2.1.4, but you'll have cryptography 1.9 which is incompatible.

解决方法:

卸载冲突库后重新make编译即可。

ChrisdeMacBook-Pro:depends chris$ pip2 uninstall cryptography
Uninstalling cryptography-1.9:
  Would remove:
    /usr/local/lib/python2.7/site-packages/cryptography-1.9.dist-info/*
    /usr/local/lib/python2.7/site-packages/cryptography/*
Proceed (y/n)? y

  Successfully uninstalled cryptography-1.9
