Webpack-关键依赖项：依赖项的请求是一个表达式 [英] Webpack - Critical dependency: the request of a dependency is an expression

问题描述

在准系统webpack项目中导入请求时，我收到三个警告消息。在 GitHub （运行 npm install 和 npm开始）。

I am getting three warning messages when importing request in a barebone webpack project. A minimal example to reproduce the bug is available on GitHub (run npm install and npm start).

关键依赖项：依赖是一个表达式

我如何摆脱此警告？

更多信息：

Webpack尝试静态解决 require 调用做一个最小的捆绑。当库在require调用中使用变量或表达式时（例如require（''+'nodent'） epoberezkin / ajv / blob / c19c02aa045f8d8fe55852b4303899f82e6de381 / lib / async.js＃L78 rel = noreferrer>这些行为 ajv ），Webpack无法静态解析它们并导入整个程序包。

Webpack tries to resolve require calls statically to make a minimal bundle. When a library uses variables or expressions in a require call (such as require('' + 'nodent') in these lines of ajv), Webpack cannot resolve them statically and imports the entire package.

我的理由是，这种动态导入在生产中是不可取的，并且最好保持代码无警告。那意味着我想要任何解决问题的解决方案。例如：

My rationale is that this dynamic import is not desirable in production, and code is best kept warning-free. That means I want any solution that resolves the problem. E.g.:

1. 手动配置webpack导入所需的库并防止出现警告。


2. 将 hack.js 文件添加到我的项目中，该文件以某种方式覆盖了require调用。


3. 升级我的库。 ajv-5.0.1-beta.3 有一个修复程序，可以消除警告。但是，如果要使用它，则必须等到它发布后，再等到 har-validator 和 request 发布后续更新。如果可以强制 har-validator 使用Beta版本的 ajv ，那将解决我的问题。


4. 其他

1. Manually configure webpack to import the required libraries and prevent the warnings from occurring.
2. Adding a hack.js file to my project that overrides the require calls in some way.
3. Upgrading my libraries. ajv-5.0.1-beta.3 has a fix that silences the warnings. However, if I want to use it, I have to wait until it is released, and then until har-validator and request release subsequent updates. If there is a way to force har-validator to use the beta version of ajv, that would solve my problem.

推荐答案

解决了 npm install request@2.79.0 --save

根据 ajv ，这个问题很可能会在几周后用最新版本的 request 解决。

According to the authors of ajv, the issue will likely be resolved in the latest version of request in a few weeks' time.
