我已经安装了 CUDA v9.0 并运行了 Windows 10
在我的编程"carreer"中大部分时间都使用Java和PHP,我现在正在尝试更深入地学习C++.为此,我使用CLion作为我的IDE - 主要是因为我非常熟悉phpStorm和IntelliJ IDEA,除了学习新语言之外我不想"学习"新的IDE.
现在,我遇到了问题,当按下Ctrl+ 时,CLion不会获取我当前的剪贴板内容V.该片段是从浏览器(Firefox 41.0.1)复制的,它既不适用于Ctrl+ 复制的代码,也不适用于C右键单击然后选择复制的代码Copy
.
看起来IDE在从外部获取剪贴板内容时遇到问题,因为在IDE内部复制和粘贴时,它的工作原理非常好.只有在尝试从其他程序粘贴某些内容时,它才会忽略它并粘贴我之前在IDE中复制的内容.
你有什么线索可以解决这个问题吗?这是一个错误还是我在我的设置或其他地方弄乱了什么?
