运行时

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。

【问题讨论】：

标签： python pip anaconda ssl-certificate ibm-watson

【解决方案1】：

从stacktrace中的错误原因来看，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（或您操作系统中的相应环境变量）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，请查看以下答案：https://stackoverflow.com/a/53310545/15385777

您也可以尝试将 pip 更新到最新版本并在检查是否可以安装 ibm-watson 之前先安装 certifi：

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

希望这个回答对你有帮助。

【讨论】：

我检查了提到的 OPENSSLDIR 路径不存在。但是我尝试安装 OpenSSL 并在环境变量中添加了一个路径。并且还要安装 git。但我仍然无法安装 ibm_watson。请你指导我。如果我在配置中犯了任何错误
你的操作系统和 pip 版本是什么？
我使用的是 Windows 10，pip 版本是“pip 21.0.1 from c:\users\test\anaconda3\lib\site-packages\pip (python 3.8)”
你能用pip安装certifi吗？
非常感谢范德雷。它在卸载 Git 3rd 方应用程序后突然工作。需要安装 OPENSSL 证书。
