使用 pip (python) 为 ibm_db 安装错误

Question

I have tried upgrading pip, installing/upgrading setup tools, a lot of these simple things suggested on here. Can anyone help? Thanks,

I've been able to install every other python library without issue.

Collecting ibm_db==3.0.3 Using cached ibm_db-3.0.3.tar.gz (794 kB) ERROR: Command errored out with exit status 1:

TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

Answer 1

The evidence is:

sock.connect(sa) TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

The python ibm_db module by default will try to download from IBM the tiny footprint db2cli driver. This is what is failing in your case.

This failure can be either a configuration error (on your environment, or your network), or it can be that the IBM website that hosts the db2cli package is temporarily unavailable. More suggestions here . Remember that the db2cli driver is independent of python ibm_db, and can be separately installed.

But, if you already have installed a Db2 CLI driver on your workstation, then you can tell python ibm_db to not download db2cli during pip install ibm_db by setting the IBM_DB_HOME environment variable before running the pip install ibm_db . This is documented on the python ibm_db homepage on github, which you should read. You can download and install a Db2 CLI driver from the IBM website ('Passport Advantage') or you can get a CLI driver from your Db2 DBA at your site. If you already installed a Db2-server on your MS-Windows workstation the it already includes the full Db2 CLI client.

So there are 4 possible CLI drivers from IBM you can use with python ibm_db, (1) the full Db2-client (2) the Db2 runtime client (3) the db2cli tiny footprint client, (4) ( for connecting to i-series AS/400 only, the IBM i access odbc package. Any of these can be pre-installed and pre-configured before installing python ibm_db as long as you set the IBM_DB_HOME variable before running pip install ibm_db .

Before python ibm_db can connect to a Db2 database, there must exist at least one Db2 CLI driver on your PATH. You can install and configure a Db2 CLI driver independently of python ibm_db if you wish to avoid install-time dependencies on the db2cli driver.
