关于 Clion 配置过程中编译失败的问题

2019-11-25

导师给了一个活儿，需要重新拾起 C++，无奈的我把虚拟机重新安装了一下，装上了 VS。但是 Win 的整体风格编程的时候实在难受，于是想到了 Jetbrains，反正有学生邮箱，就用 Clion吧。

下载安装一切正常，跑一个实例程序就开始报错了：

  It fails with the following output:

以前的习惯是一有问题先百度谷歌，发现没有。自己仔细看了报错内容后，发现是 CMake 的 clang 包损坏了。重新升级安装了 anaconda，去 CMake 官网下载了app，添加系统路径后，搞定！
所以说，还是先要仔细看报错内容，有时候更节省时间。
