美好的一天! 我有下一个项目结构:
config.json
tests/
-test_tcp.py
test_tools/
-include_proto.py
在我的'test_tcp.py'文件中,我有下一个代码:
#! /usr/bin/python3
from google.protobuf import text_format
from test_tools import include_proto # the problem is here
import test_tools.temp_proto.timeline_api_pb2 as timeline_proto
import socket
...
我尝试使用下一个命令开始我的测试:python3 tests/test_tcp.py
(我也尝试调用pytest .
命令,但我认为在这种情况下它没有价值)。所以,我有预期的错误ImportError: No module named 'test_tools'
。
我已经阅读了文档'man python3'并找到了下一个:
PYTHONPATH
Augments the default search path for module files. The format is the same as the
shell's $PATH: one or more directory pathnames separated by colons. Non-existent
directories are silently ignored. The default search path is installation depen‐
dent, but generally begins with ${prefix}/lib/python<version> (see PYTHONHOME
above). The default search path is always appended to $PYTHONPATH. If a script
argument is given, the directory containing the script is inserted in the path in
front of $PYTHONPATH. The search path can be manipulated from within a Python pro‐
gram as the variable sys.path.
因此,我使用我的根测试项目目录通过命令PYTHONPATH
设置PYTHONPATH=$(pwd)
。但是,我仍然有同样的错误。
怎么了? 对于这样的情况,是否存在任何良好的做法?
答案 0 :(得分:0)
将空__init__.py
文件添加到 test_tools 文件夹,让python知道它是一个模块。
