二郎不与Visual Studio代码终端内工作

Question

目前我正与Visual Studio代码和Erlang的问题，我有我的电脑上安装二郎/ OTP，我已经安装了Visual Studio代码Erlang的插件，但是我无法从内部终端窗口运行erlang。当我尝试我收到此错误：

erl : The term 'erl' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the 
path is correct and try again. 
At line:1 char:1 
+ erl 
+ ~~~ 
+ CategoryInfo   : ObjectNotFound: (erl:String) [], CommandNotFoundException 
+ FullyQualifiedErrorId : CommandNotFoundException 

任何帮助，将不胜感激。

Answer 1

从VS docs

The shell [that is] used [by VS] defaults to $SHELL on Linux and OS X, and %COMSPEC% on Windows. These can be overridden manually by setting terminal.integrated.shell.* in settings.

所以我会检查值是您%COMSPEC%环境变量的内容。或者，您可以覆盖在VS设置%COMSPEC%：

从VS docs：

Correctly configuring your shell on Windows is a matter of locating the right executable. VS Code defaults to the %COMSPEC% environment variable on Windows which typically points to the 32-bit version of cmd.exe.

Below are a list of common shell executables and their default locations:

// 64-bit cmd if available, otherwise 32-bit 
"terminal.integrated.shell.windows": "C:\\Windows\\sysnative\\cmd.exe" 
// 64-bit PowerShell if available, otherwise 32-bit 
"terminal.integrated.shell.windows": "C:\\Windows\\sysnative\\WindowsPowerShell\\v1.0\\powershell.exe" 
// Git Bash 
"terminal.integrated.shell.windows": "C:\\Program Files\\Git\\bin\\bash.exe" 
// Bash on Ubuntu (on Windows) 
"terminal.integrated.shell.windows": "C:\\Windows\\sysnative\\bash.exe" 

您可能还需要检查路径Erlang是在%PATH%环境变量中，如果没有添加它。您是否曾经成功启动过erlang shell，例如在安装erlang之后测试它是否正常工作？
