[英]How to fix the this on npm install: (npm ERR! install Couldn't read dependencies )?
您好我在安裝npm時遇到問題:我嘗試刪除並重新安裝但不起作用,甚至刪除所有文件夾。

NPM告訴你發生了什么:
> npm ERR! File: /home/lucas/package.json
> npm ERR! Failed to parse package.json data.
> npm ERR! package.json must be actual JSON, not just JavaScript.
> npm ERR!
> npm ERR! This is not a bug in npm.

確保您的JSON文件有效。 您可以在JSONLint上進行檢查 。 以下是依賴項部分的外觀。 注意周圍的對象括號。
{ "dependencies" :
{ "foo" : "1.0.0 - 2.9999.9999"
, "bar" : ">=1.0.2 <2.1.2"
, "baz" : ">1.0.2 <=2.3.4"
, "boo" : "2.0.1"
, "qux" : "<1.0.0 || >=2.3.1 <2.4.5 || >=2.5.2 <3.0.0"
, "asd" : "http://asdf.com/asdf.tar.gz"
, "til" : "~1.2"
, "elf" : "~1.2.3"
, "two" : "2.x"
, "thr" : "3.3.x"
, "lat" : "latest"
, "dyl" : "file:../dyl"
}
}
請參閱這篇關於NPM文檔的“依賴項”部分的文章,並確保您的package.json
部分看起來相似,尤其是“依賴”之前的任何字符。
