如果你正在使用安装脚本/实用程序(例如setuptools)来部署你的包，不要忘记将相应的文件/模块添加到安装程序中。

在支持的情况下，使用find_packages()或类似的方法自动向设置脚本添加新包。这绝对会让你免于头疼，尤其是当你把项目搁置一段时间，然后再添加一些东西的时候。

import setuptools

setuptools.setup(
    name="example-pkg",
    version="0.0.1",
    author="Example Author",
    author_email="author@example.com",
    description="A small example package",
    packages=setuptools.find_packages(),
    classifiers=[
        "Programming Language :: Python :: 3",
        "Operating System :: OS Independent",
    ],
    python_requires='>=3.6',
)

(示例取自setuptools文档)

如果你时间紧迫，其他方法都失败了:

import sys
import os
wd = '/path/to/current/script/'
sys.path.append(wd)
os.chdir(wd)
print(os.getcwd())
print(sys.path)

在我的例子中，因为我使用PyCharm和PyCharm为项目文件夹中的每个项目创建了一个“venv”，但它只是python的一个迷你env。虽然您已经在Python中安装了所需的库，但在您的自定义项目“venv”中，它不可用。这是PyCharm中出现'ImportError: No module named xxxxxx'的真正原因。 要解决此问题，您必须按以下步骤向项目自定义env添加库:

在PyCharm中，从菜单“文件”->设置 在“设置”对话框中，输入“项目:XXXProject->项目解释器” 点击“添加”按钮，会弹出“Available Packages”对话框 搜索你的库，点击“安装包” 然后，所有你需要的包将安装在你的项目自定义的“venv”文件夹。

享受。

根据你对orip帖子的评论，我猜事情是这样的:

You edited __init__.py on windows. The windows editor added something non-printing, perhaps a carriage-return (end-of-line in Windows is CR/LF; in unix it is LF only), or perhaps a CTRL-Z (windows end-of-file). You used WinSCP to copy the file to your unix box. WinSCP thought: "This has something that's not basic text; I'll put a .bin extension to indicate binary data." The missing __init__.py (now called __init__.py.bin) means python doesn't understand toolkit as a package. You create __init__.py in the appropriate directory and everything works... ?

我的观点是:

随地吐痰:

Traceback (most recent call last):
      File "bash\bash.py", line 454, in main
        import bosh
      File "Wrye Bash Launcher.pyw", line 63, in load_module
        mod = imp.load_source(fullname,filename+ext,fp)
      File "bash\bosh.py", line 69, in <module>
        from game.oblivion.RecordGroups import MobWorlds, MobDials, MobICells, \
    ImportError: No module named RecordGroups

This confused the hell out of me - went through posts and posts suggesting ugly syspath hacks (as you see my __init__.py were all there). Well turns out that game/oblivion.py and game/oblivion was confusing python which spit out the rather unhelpful "No module named RecordGroups". I'd be interested in a workaround and/or links documenting this (same name) behavior -> EDIT (2017.01.24) - have a look at What If I Have a Module and a Package With The Same Name? Interestingly normally packages take precedence but apparently our launcher violates this.

编辑(2015.01.17):我没有提到我们使用一个自定义启动器解剖这里。

所有python文件的文件编码必须为utf-8。
