`npm install`總是從package.json安裝所有內容

Question

我試圖建立一些依賴於幾個Node模塊的CI測試，但不需要在package.json中安裝所有內容。 我想我可以這樣做：

npm install --no-save eslint stylelint stylelint-config-standard stylelint-order stylelint-scss

但是，這樣做仍然將我的devDependencies中的所有內容安裝在package.json中。 我怎樣才能告訴NPM忽略我的package.json，而只安裝我專門告訴它的內容？

編輯：為了更好地說明我node_modules的問題，我從我的一個項目中刪除了node_modules ，並嘗試運行npm install --no-save mkdirp 。 mkdirp是一個非常簡單的模塊，具有一個依賴性，但是從下面的輸出中可以看到，NPM繼續進行，仍然將所有內容安裝在我的package.json 。

Answer 1

我已經弄清楚了為什么會這樣。 顯然，如果您有package-lock.json ，則NPM始終在其中安裝所有內容，而不管您傳遞的標志如何。 解決方案是--no-package-lock標志。

npm install --no-package-lock --no-save --quiet stylelint-config-standard stylelint-order stylelint-scss

Answer 2

根據npm文檔，您只能安裝dependencies ，而不能安裝其他任何項。 https://docs.npmjs.com/cli/install

使用--production標志（或將NODE_ENV環境變量設置為production時），npm將不會安裝devDependencies中列出的模塊。

注意：--production標志在向項目添加依賴項時沒有特殊含義。

因此，只需運行npm install --production
