今天用CLion開啟老師不值得專案是發生了不知名的錯誤，明明和跟著步驟走的但最終卻執行失敗。

提示資訊如下

CMake Error at E:/Clion/CLion 2017.3.4/bin/cmake/share/cmake-3.9/Modules/CMakeTestCCompiler.cmake:51 (message):   The C compiler "E:/codeblocks/MinGW/bin/gcc.exe" is not able to compile a   simple test program.

  It fails with the following output:

執行按鈕也是灰色的

以上大部分資訊無用，最重要的一句為

The C compiler "E:/codeblocks/MinGW/bin/gcc.exe" is not able to compile a   simple test program.

還有諸如 鏉� 的亂碼

問題就在這裡了，由此想到編碼問題，像極了以前遇到過的中文匯入出現亂碼。於是查看了專案的路徑

C:\Users\admin\Desktop\雜\DongmenDB-master

解決方法

將專案檔名改為英文，即路徑中不能存在中文。

所以以後還是儘量使用英文檔名吧。
