我已经更新了组件版本、软件版本和发布日期,但是每当我在带有预安装软件的文件夹上运行第二次安装时-我就会得到The folder you selected already exists and contains an installation. Chose different target for installation.
任何关于如何使用Qt installer Framework更新现有安装的提示都将非常受欢迎!
我无法在shell中导入Python2.7中的numpy。我用brew install安装了Python,然后用sudo pip install安装了numpy。我在没有sudo的情况下尝试过,但是我得到了一个拒绝权限的错误。总之,我明白了:

我在MacOS10.8.5和QT5.1.1上工作,其中包括qdebug类,它可以很好地处理某些项目,而不与其他项目一起编译。我已经尝试过重新安装Qt,这并没有改变任何事情。
这当然是由于SDL库的使用(?!)但过去效果很好。以下是编译输出的一部分:
