什么是npm命令来全局安装devDependencies？

Question

我更喜欢键入一个简短的命令，比如npm install -g来设置项目的全局依赖项，比如node-sass和jshint，而不是手动输入npm install -g every single package。有没有npm-idiomatic方法呢？

Answer 1

You are using npm install -g <pkg> wrong here. -g indicates, that it's no project dependencies, than rather you global (PC wide).

Those plugins are no devDependencies, but CLI runners. What you want is npm install --save-dev every single package upon initialisation. When you need to install those dependencies again you'd just run npm install and include something like ./node_modules/.bin/jshint to your package.json scripts in order not to depend on the CLIs.

我知道您不应该这样做，但是如果您仍然想要它，请更改您的全球位置以确保您拥有权限。安装 jq（下载它，或者 apt install jq）然后：

export NPM_CONFIG_PREFIX=~/npm-global
cat ./package.json | jq '.devDependencies | keys[] as $k | "\($k)@\(.[$k])"' | xargs -t npm install --global 

这将从 devDependencies 部分创建一个包和版本列表，将其通过管道传输到 xargs，并使用它们调用 npm install。
