PyCharm 强调django.db并抱怨：Unresolved reference 'django'.

How do I get PyCharm to recognize Django?

如何让 PyC​​harm 识别 Django？

回答by Elisabeth Shevtsova

I assume you're using a virtualenv which is located in the same directory as other project files. Python should know exactly that path. So, it's possibly that Pycharm is using the wrong Interpreter.

我假设您使用的是与其他项目文件位于同一目录中的 virtualenv。Python 应该确切地知道那条路径。因此，Pycharm 可能使用了错误的解释器。

Go to Settings -> Project: -> Project Interpreter -> switch to the right path

转到设置-> 项目：-> 项目解释器-> 切换到正确的路径

In the interpreter packages, there should be Django package installed. If not, do it here/in terminal.

在解释器包中，应该安装了 Django 包。如果没有，请在此处/在终端中执行。

I got this problem and it stopped my unit tests from running.

我遇到了这个问题，它阻止了我的单元测试运行。

I found that PyCharm, during an upgrade, had set my Python Interpreterto one which was in a virtual environment, which I do not use any more for this project. So I set it to my global Python environment in C:\Pythonand everything works like a charm.

我发现 PyCharm 在升级过程中将 my 设置Python Interpreter为虚拟环境中的一个，我不再在这个项目中使用它。所以我将它设置到我的全局 Python 环境中C:\Python，一切都像魅力一样。

If you create the project use python2.7, and in python2.7 path you installed the django, the project works normal. Then you switch the Project Interpreter to the python3.5, but this path did not install the django, then you will get this issue.

如果使用python2.7创建项目，并且在python2.7路径下安装了django，则项目正常运行。然后你把Project Interpreter切换到python3.5，但是这个路径没有安装django，那么就会出现这个问题。

if you have installed Django successfully before, in a different location from project location: in pycharm go to the setting>Project>project interpreter. right side of the Project Interpreter, click on setting icon and choose add local.

如果您之前已经成功安装了 Django，请在与项目位置不同的位置：在 pycharm 中转到setting> Project> project interpreter。在 Project Interpreter 的右侧，单击设置图标并选择add local。

then in New Environment check these two checkbox:

然后在新环境中选中这两个复选框：

• inherit global site-packages
• make available to all projects

• 继承全局站点包
• 提供给所有项目

then press Okand Applybutton and wait installing the interpreter to your project location.

然后按Ok和Apply按钮并等待将解释器安装到您的项目位置。

You can make pyCharm recognize it by setting it to use your virtualenv setup that I assume you had it already for the project

您可以通过将其设置为使用您的 virtualenv 设置来使 pyCharm 识别它，我假设您已经为该项目设置了它

STEP 1: open preferences PyCharm > Preferences

第 1 步：打开首选项PyCharm > Preferences

STEP 2:Search for interpreterand on the right window, select your virtual environment to be used in Project Interpreter

STEP 2:搜索interpreter并在右侧窗口中，选择您要使用的虚拟环境Project Interpreter

STEP 3 (ADDITIONAL):adding your environment to the list if it didn't show up

第 3 步（附加）：如果您的环境没有出现，请将其添加到列表中

1. select show all interpreter, and then on the pop up window, click + icon on the bottom left

2. select radio button Existing Environmentand select your virtual env, and then check "Make available for all project" if you use the env for other project, and click ok

1. 选择显示所有解释器，然后在弹出窗口中，单击左下角的 + 图标

2. 选择单选按钮Existing Environment并选择您的虚拟环境，如果您将环境用于其他项目，然后选中“对所有项目可用”，然后单击确定

STEP 4:On the preferences window, click apply or straight click the ok button. wait couple second and django variable should be available in your project

第 4 步：在首选项窗口中，单击应用或直接单击确定按钮。等待几秒钟，django 变量应该在您的项目中可用
