此类问题我们需要在运行应用程序时设置一个标志

不同种类的权限

--allow-env                    
    Allow environment access

--allow-hrtime                 
    Allow high resolution time measurement

--allow-net=<allow-net>        
    Allow network access

--allow-plugin                 
    Allow loading plugins

--allow-read=<allow-read>      
    Allow file system read access

--allow-run                    
    Allow running subprocesses

--allow-write=<allow-write>    
    Allow file system write access
    deno run -allow-all app.ts

例子

  //Give an environment permission
  deno run --allow-env app.ts

  //Give an all permission 
  deno run -allow-all app.ts 
  OR
  deno run -A app.ts
