Python PyCharm 中未解决的参考问题

Unresolved reference issue in PyCharm

提问by prosseek

I have a directory structure

我有一个目录结构

├── simulate.py
├── src
│?? ├── networkAlgorithm.py
│?? ├── ...

And I can access the network module with sys.path.insert().

我可以使用sys.path.insert().

import sys
import os.path
sys.path.insert(0, "./src")
from networkAlgorithm import *

However, pycharm complains that it cannot access the module. How can I teach pycham to resolve the reference?

但是，pycharm 抱怨它无法访问该模块。我怎样才能教 pycham 解决参考问题？

Manually adding it as you have done isindeed one way of doing this, but there is a simpler method, and that is by simply telling pycharm that you want to add the srcfolder as a source root, and then adding the sources root to your python path.

手动将其添加为你所做的确实这样做的一种方式，但有一个简单的方法，那就是通过简单地告诉pycharm要在添加src文件夹作为源根目录，然后添加源根你的Python小路。

This way, you don't have to hard code things into your interpreter's settings:

这样，您不必将内容硬编码到解释器的设置中：

• Add srcas a source content root:

• 添加src为源内容根：

                           

                           

• Then make sure to add add sources to your PYTHONPATH:

• 然后确保将添加源添加到您的PYTHONPATH：

• Now imports will be resolved:

• 现在进口将得到解决：

                     

                     

This way, you can add whatever you want as a source root, and things will simply work. If you unmarked it as a source root however, you willget an error:

通过这种方式，您可以添加任何您想要的作为源根目录，一切都会正常工作。但是，如果您取消将其标记为源根目录，则会出现错误：

Normally, $PYTHONPATH is used to teach python interpreter to find necessary modules. PyCharm needs to add the path in Preference.

通常，$PYTHONPATH 用于教 python 解释器找到必要的模块。PyCharm 需要在 Preference 中添加路径。

Many a times what happens is that the plugin is not installed. e.g.

很多时候会发生插件未安装的情况。例如

If you are developing a django project and you do not have django plugin installed in pyCharm, it says error 'unresolved reference'. Refer: https://www.jetbrains.com/pycharm/help/resolving-references.html

如果你正在开发一个 django 项目并且你没有在 pyCharm 中安装 django 插件，它会显示错误“未解析的引用”。参考：https: //www.jetbrains.com/pycharm/help/resolving-references.html

Please check if you are using the right interpreter that you are supposed to. I was getting error "unresolved reference 'django' " to solve this I changed Project Interpreter (Changed Python 3 to Python 2.7) from project settings: Select Project, go to File -> Settings -> Project: -> Project Interpreter -> Brows and Select correct version or Interpreter (e.g /usr/bin/python2.7).

请检查您是否使用了正确的口译员。我收到错误“未解析的引用'django'”来解决这个问题我从项目设置中更改了项目解释器（将 Python 3 更改为 Python 2.7）：选择项目，转到文件 -> 设置 -> 项目： -> 项目解释器 -> 眉毛并选择正确的版本或解释器（例如/usr/bin/python2.7）。

After testing all workarounds, i suggest you to take a look at Settings -> Project -> project dependenciesand re-arrange them.

在测试了所有解决方法后，我建议您查看Settings -> Project -> project dependencies并重新安排它们。

1. check for __init__.pyfile in srcfolder
2. add the srcfolder as a source root
3. Then make sure to add add sources to your PYTHONPATH(see above)
4. in PyCharm menu select: File --> Invalidate Caches / Restart

1. 检查__init__.py文件src夹中的文件
2. 将src文件夹添加为源根
3. 然后确保将添加源添加到您的PYTHONPATH（见上文）
4. 在 PyCharm 菜单中选择：File --> Invalidate Caches / Restart

Generally, this is a missing package problem, just place the caret at the unresolved reference and press Alt+Enterto reveal the options, then you should know how to solve it.

一般来说，这是一个缺少包的问题，​​只需将插入符号放在未解析的引用处并按Alt+Enter显示选项，然后您应该知道如何解决它。

If anyone is still looking at this, the accepted answer still works for PyCharm 2016.3 when I tried it. The UI might have changed, but the options are still the same.

如果有人还在看这个，当我尝试它时，接受的答案仍然适用于 PyCharm 2016.3。UI 可能已更改，但选项仍然相同。

ie. Right click on your root folder --> 'Mark Directory As' --> Source Root

IE。右键单击您的根文件夹-->“将目录标记为”--> 源根目录

Pycharm uses venv. In the venv's console you should install the packages explicitly or go in settings -> project interpreter -> add interpreter -> inherit global site-packages.

Pycharm 使用 venv。在 venv 的控制台中，您应该明确安装软件包或进入settings -> project interpreter -> add interpreter -> inherit global site-packages.

Install via PyCharm (works with Community Edition). Open up Settings > Project > Project Interpreterthen click the green + icon in the screenshot below. In the 2nd dialogue that opens, enter the package name and click the 'Install Package' button.

通过 PyCharm 安装（适用于社区版）。打开，Settings > Project > Project Interpreter然后单击下面屏幕截图中的绿色 + 图标。在打开的第二个对话框中，输入包名称并单击“安装包”按钮。
