Build electron-process.env.NODE_env始终为'；发展'；即使在生产中

我正在尝试用electron builder构建我的electron应用程序，运行的命令是“纱线运行构建”。 process.env.NODE_env值即使在生产中也始终为“开发”。 我试图在package.json中设置，在build命令之前的脚本前缀NODE_ENV=production下，实际值仍然是“development”而不是“production”。 如何修复NODE_ENV变量使其正确取决于其环境？ 非常感谢

下面附上package.json

在

.electron vue/build.js

文件顶部设置值a。它是在构建时被调用的文件

process.env.NODE_env='production'；
