How to suppress npm WARN deprecated messages in bash
提问by Alexander
I have several version of node.jsinstalled in Linux Mint 18.0. I manage them using nvm. Because of a project dependency, I need to have version 0.10 as the default version (nvm use 0.10). As a result of this, every time I start my terminal, I get the following output:
我node.js在 Linux Mint 18.0中安装了多个版本。我使用nvm. 由于项目依赖性，我需要将版本 0.10 作为默认版本 ( nvm use 0.10)。因此，每次启动终端时，都会得到以下输出：
npm WARN deprecated This version of npm lacks support for important features,
npm WARN deprecated such as scoped packages, offered by the primary npm
npm WARN deprecated registry. Consider upgrading to at least npm@2, if not the
npm WARN deprecated latest stable version. To upgrade to npm@2, run:
npm WARN deprecated
npm WARN deprecated npm -g install npm@latest-2
npm WARN deprecated
npm WARN deprecated To upgrade to the latest stable version, run:
npm WARN deprecated
npm WARN deprecated npm -g install npm@latest
npm WARN deprecated
npm WARN deprecated (Depending on how Node.js was installed on your system, you
npm WARN deprecated may need to prefix the preceding commands with `sudo`, or if
npm WARN deprecated on Windows, run them from an Administrator prompt.)
npm WARN deprecated
npm WARN deprecated If you're running the version of npm bundled with
npm WARN deprecated Node.js 0.10 LTS, be aware that the next version of 0.10 LTS
npm WARN deprecated will be bundled with a version of npm@2, which has some small
npm WARN deprecated backwards-incompatible changes made to `npm run-script` and
npm WARN deprecated semver behavior.

You can suppress or quieten NPM via an environment variable:
您可以通过环境变量抑制或静默 NPM：
npm_config_loglevel=silent npm version
This should work in your .bashrc(or wherever you invoke nvm):
这应该适用于您.bashrc（或您调用的任何地方nvm）：
npm_config_loglevel=silent nvm use 0.10
Or you can set the environment variable globally
或者你可以全局设置环境变量
export npm_config_loglevel=silent
Different loglevels can be found here- they are:
可以在此处找到不同的日志级别- 它们是：
"silent", "error", "warn", "http", "info", "verbose", "silly"
“无声”、“错误”、“警告”、“http”、“信息”、“详细”、“愚蠢”

You can also add .npmrc file in your project, user directory or globally. The four relevant files are:
您还可以在您的项目、用户目录或全局中添加 .npmrc 文件。四个相关文件是：
- per-project config file (/path/to/my/project/.npmrc)
- per-user config file (~/.npmrc)
- global config file ($PREFIX/etc/npmrc)
- npm builtin config file (/path/to/npm/npmrc)
- 每个项目的配置文件（/path/to/my/project/.npmrc）
- 每个用户的配置文件 (~/.npmrc)
- 全局配置文件 ($PREFIX/etc/npmrc)
- npm 内置配置文件 (/path/to/npm/npmrc)
Example:
例子：
prefix=~/.npm-global
loglevel=error

You can do this inside your script by removing the event listeners
您可以通过删除事件侦听器在脚本中执行此操作
#!/usr/bin/env node
process.removeAllListeners('warning');
// Do your thang without triggering warnings
