【QT】error: Failed to retrieve MSVC Environment from "VCvcvarsall.bat": 需要删mysql环境变量。

安装QT后直接打开，报错。

error: Failed to retrieve MSVC Environment from "D:EnglishpathVS2013VCvcvarsall.bat": 'MYSQL' is not recognized as an internal or external command, operable program or batch file. 'MYSQL' is not recognized as an internal or external command, operable program or batch file.

加入三个路径到系统环境变量。

C:WindowsSystem32

C:Windows

C:WindowsSystem32Wbem

还是不行。

把系统环境变量path下的有关mysql的全删了。

ok。
