Extraneous Package when Installed Locally
提问by moey
I was trying to install phantomjsin order to make testTwitter Bootstrap. After I had installed it locally i.e. npm install phantomjs, it reported that the package was extraneous.
我试图安装phantomjs以便make testTwitter Bootstrap。我在本地 ie 安装它后npm install phantomjs，它报告说这个包是无关紧要的。
├─┬ [email protected] extraneous
│ ├── [email protected]
...
npm ERR! extraneous: [email protected] /Users/admin/bootstrap/node_modules/phantomjs
npm ERR! not ok code 0
However, when phantomjswas installed globally i.e. npm install phantomjs -g, it worked fine i.e. no extraneous error reported.
然而，当phantomjs被全局安装时npm install phantomjs -g，它工作正常，即没有报告无关的错误。
Questions:
问题：
- Is it because phantomjsnot specified in the package.jsonfile?
- General question: Can we have any package e.g. phantomjsinstalled globally and also locally?
- 是因为package.json文件中没有指定phantomjs吗？
- 一般问题：我们可以在全球和本地安装任何包，例如phantomjs吗？
回答by TheHippo
- Yes. (Re-installing with
npm installwont install phantom.js again.) (Btw.:npm install xxx --savewill automatically add xxx to the package.json) - Yes. Local package versions are preferred over global ones. (Although you need some path handling for executables.)
- 是的。（重新安装
npm install不会再次安装phantom.js。）（顺便说一句：npm install xxx --save会自动将xxx添加到package.json中） - 是的。本地包版本优于全局包版本。（尽管您需要对可执行文件进行一些路径处理。）
回答by Jamil Abdallah
phantomjs should be included in your local .json package(manually editing it or using --save command see TheHippo's answer). If it is installed somewhere and you don't need it use the prune command
npm prune
phantomjs 应该包含在您本地的 .json 包中（手动编辑它或使用 --save 命令查看 TheHippo 的答案）。如果它安装在某个地方并且您不需要它，请使用 prune 命令
npm prune
will remove all non-required packages.
将删除所有不需要的包。
To install an item both locally and globally use:
sudo npm install -g phantomjs
要在本地和全局安装项目，请使用：
sudo npm install -g phantomjs
