解决方案

默认情况下，PyCharm使用pip管理项目包.要管理用于项目解释程序的Python程序包，请在项目设置/首选项中选择项目解释器"页面，或在"Python解释器"小部件中选择解释器设置.

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，以在所选项目中安装Python软件包.

搜索烧瓶.选择它，然后单击可用软件包"窗口左下角的安装软件包按钮进行安装.PyCharm将自动为您选择软件包版本，或者您可以选中指定版本左侧的复选框，然后从指定版本下拉菜单中选择软件包版本.

只要您

然后选中继承全局站点包复选框，然后单击创建项目"窗口右下角的创建按钮.

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.
