我正在使用适用于 Visual Studio 的 Visual Studio 2013 Node.js 工具。

我想将 Protractor 更新为:

https://www.npmjs.org/package/protractor

在 Visual Studio 的 npm 下,我看到它显示我有 protractor@0.24.2 模块。当我右键单击它并选择

update npm module

它去

https://registry.npmjs.org/protractor

当我在我的 URL 中输入它时,它在第一行显示 1.0.0-rc2 作为最新版本:

https://registry.npmjs.org/protractor

{"_id":"protractor","_rev":"103-dc957e08fce862ad70c481b4a2327ee6",
"name":"protractor","description":"Webdriver E2E test wrapper for Angular.",
"dist-tags":{"latest":"1.0.0-rc2"},
"versions":{"0.1.0":{"name":"protractor",
"description":"End to End test helpers for Angular.",
"homepage":"https://github.com/juliemr/protractor","keywords":

在输出窗口中显示更新:

我想知道的是,如果第一行显示 1.0.0-rc2 为最新版本,那么为什么它仍然显示 protractor 0.24.2 作为更新后下载的版本?

最佳答案

“npm update”命令实际上不会无条件地升级包。它只是将包升级到 package.json 文件中为您的依赖项及其子依赖项指定的最大允许语义版本。要实际升级到较新的版本,您有两种选择:

  1. 使用“npm install”并指定要安装的版本。您可以使用“最新”标签来指定最新版本,而无需查找。使用“--save”标志让 npm 编辑您的 package.json 文件并更新到新版本。

    npm install protractor@latest --save

  2. 编辑 package.json 并找到包含“protractor”的行:“0.24.2”并将版本更改为“1.0.0-rc2”(或您想要的任何版本)。然后,您可以在更改并保存文件后运行“npm update”或“npm install”。
