Python3.x Snakemake 'run' 指令不产生错误信息

当我在snakemake中使用run指令(使用python代码)时，它不会产生任何用于故障排除的错误消息.

这里是一个使用snakemake 7.8.3和python 3.9.13的简单示例.

蛇形文件:

def useless_function():
    return[thisVariableAlsoDoesntExist]

rule all:
    input: "final.txt"

rule test:
    output: "final.txt"
    run:
        print(thisVariableDoesNotExist)
        useless_function()

标准:

Building DAG of jobs...
Using shell: /usr/bin/bash
Provided cores: 1 (use --cores to define parallelism)
Rules claiming more threads will be scaled down.
Job stats:
job      count    min threads    max threads
-----  -------  -------------  -------------
all          1              1              1
test         1              1              1
total        2              1              1

Select jobs to execute...

[Mon Jul 25 18:59:13 2022]
rule test:
    output: final.txt
    jobid: 1
    reason: Missing output files: final.txt
    resources: tmpdir=/tmp

Shutting down, this might take some time.
Exiting because a job execution failed. Look above for error message

预期的错误消息(当函数和打印命令直接在python控制台上执行时):

>>> print(thisVariableDoesNotExist)

  File "<stdin>", line 1, in <module>                    
NameError: name 'thisVariableDoesNotExist' is not defined


>>> useless_function()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 2, in useless_function
