"it does not contain a package.json file." npm install問題解決
阿新 • • 發佈：2018-12-13
困擾了2個小時終於搞定。
目的是要安裝bignumber.js包
第一次出現問題：
npm WARN [email protected] No repository field.
+ [email protected]
added 1 package from 1 contributor, updated 1 package and audited 7 packages in 10.393s
found 0 vulnerabilities
說明問題主要是使用npm執行安裝時，呼叫repository(庫)失敗。
也就是說repository裡邊可能沒有bignumber的檔案。
再次執行：
npm ERR! code ENOLOCAL
npm ERR! Could not install from "node_modules/bignumber.js" as it does not contain a package.json file.
npm ERR! A complete log of this run can be found in:
npm ERR! /Users/neo/.npm/_logs/2018-10-05T09_45_26_493Z-debug.log
這次報的錯其實就已經很明顯了。在package.json指定的庫中沒有包含這個檔案。
於是，現在的任務主要就是package.json中新增包含這個檔案的庫。
直接輸入npm命令，會顯示npm的簡介資訊，裡面包含npm安裝的路徑
[email protected]:~/node_modules/neo$ npm
Usage: npm <command>
where <command> is one of:
access, adduser, audit, bin, bugs, c, cache, ci, cit,
completion, config, create, ddp, dedupe, deprecate,
dist-tag, docs, doctor, edit, explore, get, help,
help-search, hook, i, init, install, install-test, it, link,
list, ln, login, logout, ls, outdated, owner, pack, ping,
prefix, profile, prune, publish, rb, rebuild, repo, restart,
root, run, run-script, s, se, search, set, shrinkwrap, star,
stars, start, stop, t, team, test, token, tst, un,
uninstall, unpublish, unstar, up, update, v, version, view,
whoami 最後一行就是路徑：cd到那個路徑下，再cd到npm
$ cd /usr/local/lib/node_modules
$ cd npm/
裡面包含一個package.json，這個檔案就是我們要修改的檔案。
[email protected]:/usr/local/lib/node_modules/npm$ ls
AUTHORS LICENSE appveyor.yml configure lib node_modules scripts
CHANGELOG.md Makefile bin doc make.bat npmrc
CONTRIBUTING.md README.md changelogs html man package.json
然後我們直接啟動vi
$ vi package.json
在vi下，輸入’/'然後再輸入repository，再敲回車，查詢到repository的位置
2805 "repository": {
2806 "type": "git",
2807 "url": "git+https://github.com/npm/cli.git"
2808 },
我的是2805行…前面是行號，可以忽略。
儲存退出，然後再執行
$ npm install --save bignumber.js

這個是許可權拒絕。所以我們重新執行一下，請求一下許可權sudo
$ sudo npm install --save bignumber.js

回車，輸入密碼，搞定。
我們啟動一下node，試試。
$ node
> require('bignumber.js')

ROUND_CEIL: 2,
