在 Python 中安装 IBM_WATSON 库时出错

Question

虽然运行

pip install ibm_watson

我收到以下错误。我正在使用最新的 anaconda 和最新的 python 版本 3.9.2.

Answer 1

从堆栈跟踪中的错误原因判断，这个问题似乎与 ibm-watson 库无关：

'[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1123)'

首先检查 OPENSSLDIR（或 OS 中相应的环境变量）是否设置为包含您的 tls 证书的正确路径。如果您使用的是 macOS，请查看此答案：

您也可以尝试将pip更新到最新版本并先安装certifi，然后再检查是否可以安装ibm-watson：

python -m pip install --upgrade pip
pip install certifi
pip install ibm-watson

希望这个回答对您有所帮助。
