没有名为 certifi 的模块

Question

在本地目录上执行 python3 (Python 3.6.8) 脚本时，它运行良好，但在 slurm 中运行 sbatch 作业时，会抱怨 certifi。

python3 -m pip install certifi

Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: certifi in /usr/local/lib/python3.6/site-packages (2020.12.5)

添加到 python 代码后：

import sys
import os
sys.path.append(os.getcwd())

或这个：

import sys
import os
module_path = os.path.abspath(os.getcwd())

if module_path not in sys.path:

    sys.path.append(module_path)

出现同样的错误。看来certifi已经安装了。

pip show certifi

运行 python 代码后出现错误（python 代码中没有“import certifi”行）：

错误（在 python 代码中包含“import certifi”行）：

Traceback (most recent call last):
  File "/home/username/projecttest_LR_attack/LR_attack.py", line 17, in <module>
    import certifi
ModuleNotFoundError: No module named 'certifi'

问题的解决方案是什么？

Answer 1

如果您登陆此处是因为在 MacOS（或任何其他基于 python 的命令）中遇到问题httpie，请尝试使用 homebrew 安装 python-certifi。这应该作为依赖项的一部分安装，但由于某种原因它并不总是这样做。

brew install python-certifi
