NG_PERSISTENT_BUILD_CACHE=1 ng服务不工作
提问于 2022-01-20 16:07:51
我正在尝试使用角提供的持久构建缓存功能，但它看起来不适合我，我正在尝试下面的命令
NG_PERSISTENT_BUILD_CACHE=1 ng serve它总是返回错误以下。
'NG_PERSISTENT_BUILD_CACHE‘不被识别为内部或外部命令、可操作的程序或批处理文件。
我使用的是角cli版本12.2.15。我不知道我错过了什么。下面是我的packages.json文件

您似乎在使用Windows cmd运行命令，因此您将得到错误信息。
命令：
NG_PERSISTENT_BUILD_CACHE=1 ng serve适用于类似Unix的系统，无法在Windows cmd中工作。
您可以使用以下任何一种方法来使其工作：
- 首先设置环境变量，然后运行命令
// 1st command to set the environment variable
set NG_PERSISTENT_BUILD_CACHE=1
// 2nd command
ng serve- 在单步
中运行这两个命令
set NG_PERSISTENT_BUILD_CACHE=1&&ng servenpm start
- 在package.json脚本中添加以下命令，然后运行package.json
"scripts": {
"start": "set NG_PERSISTENT_BUILD_CACHE=1&&ng serve",
...
}在所有上述方法中，环境变量值都是为运行命令的会话设置的。如果要全局设置环境变量，则可以通过在“环境变量”对话框中添加系统变量来实现这一点。(系统属性、->环境变量、->系统变量)。
