Hyper终端启动出现bash: export: 无效标识符错误的解决咨询

作为编程和Hyper终端新手，每次启动终端都会弹出以下错误，虽然不影响代码运行，但希望彻底消除这些提示：

解决办法 #

问题根源 #

bash中导出包含空格的路径时，必须用双引号包裹整个PATH值。你当前的export PATH=...没有加引号，bash会把路径中的空格当成参数分隔符，导致它把Program Files这类带空格的路径拆成多个无效的标识符，从而抛出错误。

修复步骤 #

1. 打开你的.bashrc文件，找到export PATH=...这一行。
2. 给整个PATH字符串加上双引号，修改后内容如下：

export NPM_CONFIG_PREFIX=~/.npm-global
export PATH="C:/Development/ani-gen/env/Scripts:/c/Users/John/bin:/mingw64/bin:/usr/local/bin:/usr/bin:/bin:/mingw64/bin:/usr/bin:/c/Users/John/bin:/c/Program Files (x86)/Common Files/Intel/Shared Libraries/redist/intel64/compiler:/c/Windows/system32:/c/Windows:/c/Windows/System32/Wbem:/c/Windows/System32/WindowsPowerShell/v1.0:/c/Windows/System32/OpenSSH:/c/Program Files/NVIDIA Corporation/NVIDIA NvDLISR:/c/Program Files (x86)/NVIDIA Corporation/PhysX/Common:/c/WINDOWS/system32:/c/WINDOWS:/c/WINDOWS/System32/Wbem:/c/WINDOWS/System32/WindowsPowerShell/v1.0:/c/WINDOWS/System32/OpenSSH:/c/Program Files/dotnet:/c/ProgramData/chocolatey/bin:/cmd:/c/Program Files/nodejs:/c/Users/John/AppData/Local/Programs/Python/Python310:/usr/bin/vendor_perl:/usr/bin/core_perl:/c/Users/John/.npm-global/bin:~/.npm-global/bin"

3. 保存文件后，重启Hyper终端，或者执行以下命令让修改立即生效：

source ~/.bashrc

这样启动终端时就不会再弹出那些错误提示了。
