firebase部署失败

Question

嗨，在此之前我对命令没有任何问题。为此，我尝试了一些不同的解决方案，如清除缓存和firebase函数cmd。但是我总是得到这个错误。我也研究了一些资源，但没有一个有效。你们有什么建议吗?

You're about to initialize a Firebase project in this directory:
C:UsersOwnerDesktopamazon-react
Before we get started, keep in mind:
* You are initializing in an existing Firebase project directory
? Are you ready to proceed? Yes
=== Project Setup
First, let's associate this project directory with a Firebase project.
You can create multiple project aliases by running firebase use --add,
but for now we'll just set up a default project.
i  .firebaserc already has a default project, using fir-a38d0.
=== Functions Setup
A functions directory will be created in your project with a Node.js
package pre-configured. Functions can be deployed with firebase deploy.
? What language would you like to use to write Cloud Functions? JavaScript
? Do you want to use ESLint to catch probable bugs and enforce style? Yes
? File functions/package.json already exists. Overwrite? Yes
+  Wrote functions/package.json
? File functions/.eslintrc.js already exists. Overwrite? (y/N) ? File functions/index.js alre? File functions/.eslintrc.js already exists. Overwrite? Yes
? File functions/index.js already exists. Overwrite? Yes
+  Wrote functions/.eslintrc.js
+  Wrote functions/index.js
? File functions/.gitignore already exists. Overwrite? Yes
+  Wrote functions/.gitignore
? Do you want to install dependencies with npm now? Yes

1:7  error  'functions' is assigned a value but never used  no-unused-vars

这与你的eslint设置有关。你的eslint的首选项设置为抛出错误，如果你已经分配了一个值，但没有使用它。

要解决这个问题，可以:

-使用functions变量

-更改eslint的首选项以显示警告而不是错误，或者禁用eslint。

eslint是Firebase自带的一个工具，它会在部署前检查你的代码是否有错误，它对于在部署前捕获错误非常有用。就我个人而言，我将未使用的变量作为警告而不是错误，因此它仍然会部署。
