解决方案

默认情况下，PyCharm 使用 pip 来管理项目包.要管理项目解释器的 Python 包，请选择项目中的项目解释器页面Settings/Preferences 或选择 Python 解释器小部件中的 解释器设置.

选择文件 -> 设置 -> 项目: project_name -> 项目解释器.单击屏幕截图中鼠标光标标记的+按钮，在所选项目中安装Python包.

搜索烧瓶.选择它并单击可用软件包窗口左下角的 Install Package 按钮进行安装.PyCharm 会自动为您选择软件包版本，或者您可以选中 Specify version 左侧的复选框，然后从 Specify version 下拉菜单中选择软件包版本.

每当您

然后勾选Inherit global-site packages复选框并点击Create Project窗口右下角的 Create 按钮.

解决方案

By default, PyCharm uses pip to manage project packages. To manage Python packages for the project interpreter, select the Project Interpreter page in the project Settings/Preferences or select Interpreter Settings in the Python Interpreter widget.

Select File -> Settings -> Project: project_name -> Project Interpreter. Click the + button which is marked by the mouse cursor in the screenshot to install Python packages in the selected project.

Search for Flask. Select it and click the Install Package button in the lower left corner of the Available Packages window to install it. PyCharm will automatically choose the package version for you or you can check the checkbox to the left of Specify version and select the package version from the Specify version dropdown menu.

Whenever you install a Python package specifically for a project, PyCharm adds the packages that were installed to the project's venv directory where PyCharm will find them automatically.

PyCharm does not automatically find your globally installed Python packages unless the project has been configured to find them. To do this select the Inherit global-site packages option when you create a new project.

Select File -> New Project to create a new project. Click the triangle marked by the mouse cursor in the below screenshot to show the new project's options.

Then check the Inherit global-site packages checkbox and click the Create button in the lower right corner of the Create Project window.
