推荐答案

尝试修改文件并将其内容替换为以下内容:(在文件夹:node_modules\bin)

try to modify the files and replace their contents with the following: (in the folder : node_modules\bin)

修改ng.cmd:

@IF EXIST "%~dp0\node.exe" (
  "%~dp0\node.exe" --max_old_space_size=5048 "%~dp0\..\angular-cli\bin\ng" %*
) ELSE (
  @SETLOCAL
  @SET PATHEXT=%PATHEXT:;.JS;=;%
  node --max_old_space_size=5048 "%~dp0\..\angular-cli\bin\ng" %*
)

修改 ngc.cmd :

Modify ngc.cmd :

@IF EXIST "%~dp0\node.exe" (
  "%~dp0\node.exe" --max_old_space_size=5048 "%~dp0\..\@angular\compiler-cli\src\main.js" %*
) ELSE (
  @SETLOCAL
  @SET PATHEXT=%PATHEXT:;.JS;=;%
  node --max_old_space_size=5048 "%~dp0\..\@angular\compiler-cli\src\main.js" %*
)
