npm检查并更新软件包(如果需要)

问题描述

我们需要将Karma测试运行程序集成到TeamCity中，为此，我想给sys-engineers小脚本(powershell或其他工具)，该脚本将:

We need to integrate Karma test runner into TeamCity and for that I'd like to give sys-engineers small script (powershell or whatever) that would:

1. 从某些配置文件中提取所需的版本号(我想我可以将其作为注释直接放在karma.conf.js中)

检查是否已在npm的全局回购中安装了已定义的业力赛跑者版本

check if the defined version of karma runner installed in npm's global repo

，如果不是，或者安装的版本比预期的旧:请安装并安装正确的版本

if it's not, or the installed version is older than desired: pick up and install right version

运行它:karma start .\Scripts-Tests\karma.conf.js --reporters teamcity --single-run

所以我真正的问题是:如果安装了所需版本的软件包，如何才能签入脚本?".您应该进行检查，还是每次都致电npm -g install是安全的?

So my real question is: "how can one check in a script, if desired version of package installed?". Should you do the check, or it's safe to just call npm -g install everytime?

我不想总是检查并安装最新的可用版本，因为其他配置值可能不兼容

推荐答案

要检查项目中的任何模块是否旧":

To check if any module in a project is 'old':

npm outdated

'已过期'将检查package.json中定义的每个模块，并查看是否存在NPM注册表中有较新的版本.

'outdated' will check every module defined in package.json and see if there is a newer version in the NPM registry.

例如，说xml2js 0.2.6(位于当前项目的node_modules中)已过时，因为存在较新的版本(0.2.7).您会看到:

For example, say xml2js 0.2.6 (located in node_modules in the current project) is outdated because a newer version exists (0.2.7). You would see:

[email protected] node_modules/xml2js current=0.2.6

更新所有依赖项，如果您确信这是可取的:

To update all dependencies, if you are confident this is desirable:

npm update

或者，更新单个依赖项，例如xml2js:

Or, to update a single dependency such as xml2js:

npm update xml2js
