这是一个关于python运用到tkinter库的爱心动态代码
在pycharm中运行出现报错
如图1,
然后我在终端中输入python3 /Users/longweixu/Documents/python学习/python奇技淫巧/动态爱心/main.py
又可以运行
出现结果
这是怎么回事
你在PyCharm中遇到的错误可能是由于缺少特定于项目的软件包或配置引起的。当你在终端中使用`python3 /Users/longweixu/Documents/python学习/python奇技淫巧/动态爱心/main.py`运行脚本时,它可能正在使用一个不同的Python环境或正确配置的设置,从而可以无错误运行。
要解决PyCharm中的问题,可以尝试以下步骤:
1. 确保在PyCharm中为你的项目选择了正确的解释器。转到"文件" -> "设置" -> "项目" -> "Python解释器",确保它与你在终端中使用的解释器(`python3`)相匹配。如果未设置,请点击齿轮图标并选择适当的解释器。
2. 检查是否安装了所有所需的软件包。在PyCharm中,转到"文件" -> "设置" -> "项目" -> "Python解释器"。你应该看到一个已安装软件包的列表。如果有任何所需的软件包缺失,点击"+"按钮添加它们。
3. 确认你的PyCharm项目具有正确的项目结构和文件路径。确保所有文件,包括导入的模块和图片资源,相对于主脚本,位于正确的目录中。
4. 如果错误仍然存在,尝试启用PyCharm调试器以准确定位导致错误的确切行。你可以通过在代码中设置断点或在调试模式下运行脚本来实现这一点。
按照这些步骤,你应该能够解决错误,并在PyCharm中成功运行动态爱心动画。 这是你pycharm的问题吧,我用VSCode运行就没问题 前来学习{:5_109:} 本帖最后由 歌者文明清理员 于 2023-7-10 12:59 编辑
这是PyCharm的问题吧,我在mac上用idle也能搞对
pycharm创建项目时一定要勾选“inherit global packages”,这样这个项目的解释器环境就是全局环境
