當我輸入這個命令“npm install”時不安裝 node_modules

Question

當我使用此命令npm install安裝 node_modules 時，出現以下錯誤。 在這種情況下，如何修復此錯誤？

npm ERR! errno HPE_INVALID_CONSTANT
npm ERR! request to https://registry.npmjs.org/acorn/-/acorn-5.7.2.tgz failed, reason: Parse Error

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\IR-16\AppData\Roaming\npm-cache\_logs\2019-03-25T10_35_26_869Z-debug.log

我的 package.json 如下：

  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",

  },

  }
}

如您所見，從未安裝acorn包。 當我在所有項目中安裝````node modules``` 時會發生此錯誤。

Answer 1

請從package.json相關的 acorn 中刪除"acorn": "^5.7.2",並按照以下步驟操作，

rm -rf node_modules/
npm install

然后通過終端手動安裝橡子

npm install acorn --save

如果它不起作用，那么你可以嘗試

npm install acorn --unsafe-perm --save

希望能幫到你 ！！
