如何添加环境变量来启动。json在VSCode

Working with the new VSCode editor on a node.js project. I am attempting to configure my "Launch" profile for debugging by editing the launch.json file. I need to setup a connectionstring as an environment variable. According to the comments in the launch.json file:

在节点上使用新的VSCode编辑器。js的项目。我正在尝试通过编辑启动来配置我的“启动”配置文件以进行调试。json文件。我需要将connectionstring设置为环境变量。根据发布会上的评论。json文件:

// Environment variables passed to the program.
"env": { }

I have tried adding my environment variable like so:

我尝试添加环境变量如下:

"env":
{
"CONNECTION_STRING": "Data Source=server;Initial Catalog=catalog;User ID=uid;Password=pwd;MultipleActiveResultSets=true"
}

This causes an error when I try to launch my app; "OpenDebug process has terminated unexpectedly". I have not yet found any log files, etc. that might explain what the issue is.

当我试图启动我的应用程序时，这会导致一个错误;“OpenDebug进程已意外终止”。我还没有找到任何可能解释问题的日志文件等等。

I know this app works correctly when I setup the environment variable and launch my app from the standard command prompt. The app also runs as expected if I comment out my variable in the launch.json file; I just can't connect to the database.

当我安装环境变量并从标准命令提示符启动我的应用程序时，我知道这个应用程序可以正常工作。如果我在发布中注释掉我的变量，应用程序也会按预期运行。json文件;我无法连接到数据库。

I am assuming that I am using the wrong format in the launch.json file, but I have not yet found any way to make this work.

我假设我在发射中使用了错误的格式。json文件，但是我还没有找到任何方法来完成这个工作。

Any ideas?

什么好主意吗?

#1

There seems to be a problem with environment variables on Windows (and probably on linux). It does work on OS X. We are investigating. Expect a fix soon.

Windows上的环境变量似乎存在问题(可能在linux上也是如此)。它在OS x上工作，我们正在调查。希望尽快修复。

I'm successfully passing them using the env property in launch.json:

我正在使用启动中的env属性成功地传递它们。

{
  "version": "0.2.0",
  "configurations": [
    {
    "type": "node",
    "request": "launch",
    "name": "SLS Webpack",
    "protocol": "legacy",
    "program": "${workspaceRoot}/node_modules/.bin/sls",
    "cwd": "${workspaceRoot}",
    "args": ["webpack", "watch", "-f", "${fileBasenameNoExtension}", "-p", "${fileDirname}/event.json"],
    "env": {"AWS_REGION":"us-east-1", "SLS_DEBUG":"*"},
    "outFiles": ["${cwd}/dist/**/*.js"],
    "sourceMaps": true,
    "smartStep": true    
    }
  ]
}

as a workaround, you can set environment variables when starting VSCode, for example, using this little powershell script:

作为一个解决方案，您可以在启动VSCode时设置环境变量，例如，使用这个小小的powershell脚本:

param(
 $vars = @{}
)

$vars.Keys | % {
    write-host "adding env variable: $_=$($vars[$_])"
    [Environment]::SetEnvironmentVariable($_, $vars[$_], "Process")
}
$ver = "0.1.0"
& "$env:LOCALAPPDATA\Code\app-$ver\Code.exe"

Save it as vscode.ps1 and call it from commandline, like this:

vscode保存它。从命令行调用它，如下所示:

powershell ".\vscode.ps1 -vars @{ 'NODE_ENV'='test'; 'SOMETHING'='else' }"

Like this, under you OS:

像这样，在你的下面:

        "osx": {
            "MIMode": "lldb",
            "environment": [{"name": "DYLD_LIBRATY_PATH", "value": "/Users/x/boost_1_63_0/stage/lib/"}]
        },
