Windows 10 上 git-bash shell“MINGW64”的 CLI 中的“bash：export：...不是有效标识符”

Question

使用git for Windows，我在打开一个新的 git-bash 终端时总是得到以下输出：

bash: export: `C:\Users\username\Projects\proj1\src\packages\;C:\Users\username\Projects\proj2\MachineLearning\;C:\Users\username\Projects\proj2\MachineLearning\azure_components\': not a valid identifier

接下来，我通过echo $PATH 检查了PATH 变量：

C:\Users\username\Projects\proj1-venv/Scripts:/c/Users/username/bin:/mingw64/bin:/usr/local/bin:/usr/bin:/bin:/mingw64/bin:/usr/bin:/c/Users/username/bin:/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/users/username/.pyenv/pyenv-win/versions/3.9.0a4/Scripts:/c/Program Files/PuTTY:/c/Program Files/Amazon/AWSCLIV2:/c/ProgramData/chocolatey/lib/gsudo/bin:/c/Program Files/Amazon/AWSSAMCLI/bin:/c/Users/username/AppData/Local/Terraform:/c/Users/username/AppData/Local/iPython:/c/Program Files/Docker/Docker/resources/bin:/c/ProgramData/DockerDesktop/version-bin:/c/Program Files/Microsoft SQL Server/130/Tools/Binn:/c/Program Files/Microsoft SQL Server/Client SDK/ODBC/170/Tools/Binn:/c/Program Files (x86)/Microsoft SQL Server/150/DTS/Binn:/c/Program Files/Azure Data Studio/bin:/c/Users/username/.pyenv/pyenv-win/bin:/c/Users/username/.pyenv/pyenv-win/shims:/c/Users/username/.pyenv/pyenv-win/bin:/c/Users/username/.pyenv/pyenv-win/shims:/c/Users/username/AppData/Local/Microsoft/WindowsApps:/c/Users/username/AppData/Local/Programs/Microsoft_VS_Code/bin:/c/Users/username/.pyenv/pyenv-win/bin:/c/Users/username/.pyenv/pyenv-win/shims:/c/Users/username/AppData/Local/Pandoc:/c/texlive/2021/bin/win32:/c/Users/username/AppData/Local/Terraform:/c/Users/username/AppData/Local/iPython:/c/Users/username/.dotnet/tools:/c/Program Files/Azure Data Studio/bin:/usr/bin/vendor_perl:/usr/bin/core_perl

我尝试使用export $PATH 显式导出$PATH 的内容，这会多次引发相同的错误bash: export: ... not a valid identifier：

bash: export: `C:\Users\username\Projects\proj1-venv/Scripts:/c/Users/username/bin:/mingw64/bin:/usr/local/bin:/usr/bin:/bin:/mingw64/bin:/usr/bin:/c/Users/username/bin:/c/WINDOWS/system32:/c/WINDOWS:/c/WINDOWS/System32/Wbem:/c/WINDOWS/System32/WindowsPowerShell/v1.0:/c/WINDOWS/System32/OpenSSH:/c/Program': not a valid identifier

bash: export: `Files/Azure': not a valid identifier
bash: export: `Studio/bin:/c/Users/username/.pyenv/pyenv-win/bin:/c/Users/username/.pyenv/pyenv-win/shims:/c/Users/username/.pyenv/pyenv-win/bin:/c/Users/username/.pyenv/pyenv-win/shims:/c/Users/username/AppData/Local/Microsoft/WindowsApps:/c/Users/username/AppData/Local/Programs/Microsoft_VS_Code/bin:/c/Users/username/.pyenv/pyenv-win/bin:/c/Users/username/.pyenv/pyenv-win/shims:/c/Users/username/AppData/Local/Pandoc:/c/texlive/2021/bin/win32:/c/Users/username/AppData/Local/Terraform:/c/Users/username/AppData/Local/iPython:/c/Users/username/.dotnet/tools:/c/Program': not a valid identifier
bash: export: `Files/Azure': not a valid identifier
bash: export: `Studio/bin:/usr/bin/vendor_perl:/usr/bin/core_perl': not a valid identifier

我怀疑它与许多路径中的空格字符有关，这在 Windows 上很常见，但在 UNIX 系统中不喜欢。

假设这是罪魁祸首，我该如何最好地解决这个问题？ 如果是其他原因造成了这种不良行为，我也想理解这一点。

Answer 1

正如@Zilog80 在我的 OP 下的第一条评论中正确指出的那样，我必须在以下 bash 启动脚本中的 export-command 之后检查并删除所有 $：

1. .bashrc
2. .bash_profile
3. .profile

就我而言，我的~/.bashrc - 脚本中的所有大惊小怪都归结为以下行：

export $PYTHONPATH

这必须替换为

export PYTHONPATH

现在，打开一个新的终端会话不会抛出这些 "bash: export: ... not a valid identifier" - 不再是错误了。
