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，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())

或者这个：

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代码后的错误（Python代码中没有“import certifi”行）：

错误（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'

问题的解决办法是什么？

Answer 1

对于 MacOS 上的任何人并且已经运行过

pip install certifi

但仍然无法工作

转到您的

applications

文件夹 > 找到您的

python version

文件夹 -> 双击 python 文件夹中的文件

Install Certificates.command

以安装证书。

等待安装完成

之后，您可以尝试再次使用 requests 包运行代码

Answer 2

计算节点上安装的模块是否与本地安装的模块相同？您可能需要咨询 Slurm 管理员。

Answer 3

这可能意味着

/usr/local/lib/python3.6/site-packages/

不是 slurm 中的 sbatch 作业可以访问的

PYTHONPATH

环境变量。您可以在运行时添加或附加它：

import sys
sys.path.append('/usr/local/lib/python3.6/site-packages/')

Answer 4

如果您登陆此处是因为在 MacOS 中使用

httpie

（或任何其他基于 python 的命令）时遇到问题，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

Answer 5

pip 安装证书

在 CLI 上尝试此命令
