Cygwin不识别make命令，尽管它被安装在bin文件夹中
我一直试图在我的W10 PC上运行需要make的软件，这使我不得不安装Cygwin。当查看Cygwin时，我发现我需要从Devel类别中安装make，这是我第一次安装Cygwin时所做的。我第一次尝试执行make时收到以下消息
bash: make:命令找不到
我试着重新安装make (下拉列表字面上写着“重新安装”)，并检查make.exe是否在bin文件夹中，但我仍然得到了相同的错误。我第二次重新安装了它，但这次检查了src框，希望这会有所帮助，但它没有。
我想添加的唯一其他信息是，我试图创建的Makefile位于我的C驱动器(C:\Users\myname\Documents\folder\folder_with_Makefile)的Documents文件夹中的一个文件夹中。我查看了Cygwin FAQ，它提到Cygwin根目录与我的驱动器根目录在设计上是不一样的，并且只在“您知道自己在做什么”时才更改它，而我显然不知道。我不确定这是否可能是我的问题的原因，但是我很感谢您的帮助。

请参阅下面的更改，这将有助于您正确设置路径变量与cygwin。您可以执行下列更改。
打开etc/直接安装cygwin的文件profile.bashrc。
添加下面的行。
# Save Windows path variable
export WINPATH=$PATH
export PATH=/bin:/usr/bin:/usr/sbin:/usr/local/bin打开etc/直接安装cygwin的bash.bashrc文件。添加以下行
# The next block is only needed in case somebody starts a shell without --login parameter in the beginning (no /etc/profile invoked)
# The WINPATH variable is set in /etc/profile and contains the original Win PATH variable content
if [ -z "${WINPATH}" ] ; then
export WINPATH=$PATH
fi
# Set PATH variables
export PATH=/bin:/usr/bin:/usr/sbin:/usr/local/bin:${WINPATH}
export MANPATH=/usr/local/man:/usr/share/man:/usr/manStack Overflow用户

您似乎没有运行登录shell。
使用根目录中的两个批处理文件模拟效果，该文件来自预期存在的Cygwin.bat
案例1: Cygwin-nologin.bat . Case
Mintty不以login shell的形式运行bash，PATH也不包括Cygwin命令主要位于的/usr/bin/：
@echo off
setlocal enableextensions
set TERM=
cd /d "%~dp0bin" && .\mintty我运行它，其效果是：
echo $PATH
/cygdrive/c/Program Files (x86)/Intel/iCLS Client:/cygdrive/c/Program Files/Intel/iCLS Client:/cygdrive/c/WINDOWS/system32:/cygdrive/c/WINDOWS:/cygdrive/c/WINDOWS/System32/Wbem:/cygdrive/c/WINDOWS/System32/WindowsPowerShell/v1.0:/cygdrive/c/Program Files (x86)/Intel/Intel(R) Management Engine Components/DAL:/cygdrive/c/Program Files/Intel/Intel(R) Management Engine Components/DAL:/cygdrive/c/Program Files (x86)/Intel/Intel(R) Management Engine Components/IPT:/cygdrive/c/Program Files/Intel/Intel(R) Management Engine Components/IPT:/cygdrive/c/Program Files/Calibre2:/cygdrive/c/WINDOWS/System32/OpenSSH:/cygdrive/c/Program Files/Intel/WiFi/bin:/cygdrive/c/Program Files/Common Files/Intel/WirelessCommon:/cygdrive/c/Program Files (x86)/FreeFem++:/cygdrive/c/Users/Marco/AppData/Local/Microsoft/WindowsApps
$ which make
bash: which: command not found
$ /usr/bin/which make
/usr/bin/which: no make in (/cygdrive/c/Program Files (x86)/Intel/iCLS Client: ...)案例2: Cygwin-login.bat
Mintty以login shell的形式运行bash，PATH包含/usr/bin/
@echo off
setlocal enableextensions
set TERM=
cd /d "%~dp0bin" && .\mintty -区别在于最后一个-字符。man mintty获取详细信息
$ echo $PATH
/usr/local/bin:/usr/bin路径非常短，因为在我的环境中，我设置了一个特定的变量
$ set |grep NOWIN
CYGWIN_NOWINPATH=YES否则，路径将是Cygwin和Windows路径的组合，前面是Cygwin路径
$ echo ${PATH}":"${ORIGINAL_PATH}
/usr/local/bin:/usr/bin:/cygdrive/c/Program Files (x86)/Intel/iCLS Client:/cygdrive/c/Program Files/Intel/iCLS Client:/cygdrive/c/WINDOWS/system32:/cygdrive/c/WINDOWS:/cygdrive/c/WINDOWS/System32/Wbem:/cygdrive/c/WINDOWS/System32/WindowsPowerShell/v1.0:/cygdrive/c/Program Files (x86)/Intel/Intel(R) Management Engine Components/DAL:/cygdrive/c/Program Files/Intel/Intel(R) Management Engine Components/DAL:/cygdrive/c/Program Files (x86)/Intel/Intel(R) Management Engine Components/IPT:/cygdrive/c/Program Files/Intel/Intel(R) Management Engine Components/IPT:/cygdrive/c/Program Files/Calibre2:/cygdrive/c/WINDOWS/System32/OpenSSH:/cygdrive/c/Program Files/Intel/WiFi/bin:/cygdrive/c/Program Files/Common Files/Intel/WirelessCommon:/cygdrive/c/Program Files (x86)/FreeFem++:/cygdrive/c/Users/Marco/AppData/Local/Microsoft/WindowsApps在两种情况下
$ which make
/usr/bin/make
$ make --version
