找不到模块错误：没有名为“ src”的模块 [英] Module Not Found Error: No module named 'src'

问题描述

每当我在终端错误 ModuleNotFoundError中运行main.py脚本时，都不会发生名为 src的模块。

Whenever I run main.py script in terminal error 'ModuleNotFoundError: No module named 'src' ' occurs. However it runs fine in PyCharm.

项目结构：

-project
  -resources
  -src
    -package1
      -script1.py
      -script2.py
    -package2
      -script3.py
    -main.py

从终端我这样运行-

project$ python src/main.py

我遇到的错误：

Traceback (most recent call last):
  File "src/main.py", line 1, in <module>
    from src.package1 import script1
ModuleNotFoundError: No module named 'src'

我已经尝试过将文件夹/软件包'src'的绝对路径添加到sys.path

I have already tried adding absolute path of folder/package 'src' to sys.path

main.py

from src.package1 import script1
from src.package1 import script2
from src.package2 import script3

if name=="__main__":
  ...
  ...

sys.path

current sys.path is ['/home/xyz/Projects/project/src', '/home/xyz/Apps/anaconda3/envs/project/lib/python37.zip', '/home/xyz/Apps/anaconda3/envs/project/lib/python3.7', '/home/xyz/Apps/anaconda3/envs/project/lib/python3.7/lib-dynload', '/home/xyz/Apps/anaconda3/envs/project/lib/python3.7/site-packages', 'src/main.py']

推荐答案

https://docs.python.org/3/tutorial/modules.html#the-module-search-path

导入名为垃圾邮件的模块时，解释程序首先搜索具有该名称的内置模块。如果找不到，它将在变量 sys.path spam.py 的文件。 c>。从以下位置初始化 sys.path ：

When a module named spam is imported, the interpreter first searches for a built-in module with that name. If not found, it then searches for a file named spam.py in a list of directories given by the variable sys.path. sys.path is initialized from these locations:

• 包含输入脚本的目录（或未指定文件时的当前目录）。


• PYTHONPATH （目录名列表，语法与shell变量PATH）。


• 与安装有关的默认值。

• The directory containing the input script (or the current directory when no file is specified).
• PYTHONPATH (a list of directory names, with the same syntax as the shell variable PATH).
• The installation-dependent default.

由于您提供了文件 src / main.py ，因此其包含的文件夹将成为搜索根目录。您可以在不指定 src。部分的情况下导入模块。

Since you supply a file, src/main.py, its containing folder is going to be the search root. You could import the modules without specifying the src. part.
