In fact, the solution to the problem is very simple: QT does not support the path of Chinese, the source of the path of all the changes to English can solve the problem.
The first problem occurs when I run the online example program, rebuild the compilation is also an error, hint:
Cannot find FILE:F:\PRO\QT\QT5 development and instance \ Book source program \ch1\ch101\dialog\dialog.pro.
21:55:03: Process "D:\Qt\Qt5.5.0\5.5\msvc2013_64\bin\qmake.exe" exits, exit code 2.
Error while Building/deploying project Dialog (kit:desktop Qt 5.5.0 MSVC2013 64bit)
When executing step "qmake"
QT Creator is not supported for catalogs larger than two spaces and Chinese-named directories !!
The reason for this should be qmake for directories with spaces and Chinese named directories do not support!!
