MinGW: "gcc is not recognized as an internal or external command"
提问by Aviv Cohn
I downloaded and installed MinGW. I used the graphical program to install the C++ compiler.
我下载并安装了 MinGW。我使用图形程序来安装 C++ 编译器。
Typing gccin the Windows command line prints:
gcc在 Windows 命令行中键入打印：
gcc is not recognized as an internal or external command
I checked, and gcc.exeis present in C:\MinGW\bin. What's wrong?
我检查过，并且gcc.exe存在于C:\MinGW\bin. 怎么了？

Although an old question, none of the answers here helped me. The only route I found to get to my destination is by typing in the following line in my command prompt:
虽然是一个老问题，但这里的答案都没有帮助我。我发现到达目的地的唯一途径是在命令提示符中输入以下行：
After that, simply type in gcc -v.
之后，只需键入 gcc -v。
Hope this helps anyone with the problem I had!
希望这可以帮助任何人解决我遇到的问题！

Or at the command line you must type in "\mingw\bin\gcc" instead of just "gcc". Best to set the environment as mentioned above.
或者在命令行中，您必须输入“\mingw\bin\gcc”而不仅仅是“gcc”。最好设置上面提到的环境。

Please edit the Path variable to append a semicolon followed by location "C:\MinGW\bin" and do NOT use any spaces while doing so.
请编辑 Path 变量以附加一个分号，后跟位置“C:\MinGW\bin”，并且在执行此操作时不要使用任何空格。

Please try the following: click on "New" under Environmental Variables and add the following line to both user and system variables without editing:
请尝试以下操作：单击“环境变量”下的“新建”，并将以下行添加到用户和系统变量中，无需编辑：
C:\mingw32\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\

maybe this is obvious, but don't forget that the PATH environment variable is case sensitive.
也许这很明显，但不要忘记 PATH 环境变量区分大小写。
