包名称更改导致服务器错误 - 应用程序崩溃

Question

为了遵循最佳实践，

我已经相应地更改了包名称，但突然在服务器上收到错误

private@Privates-MacBook-Pro Fullstack-project % ls

PROJECT1

private@Privates-MacBook-Pro Fullstack-project % cd PROJECT1

private@Privates-MacBook-Pro PROJECT1 % ls

client          common          node_modules    package.json    server          yarn.lock

private@Privates-MacBook-Pro PROJECT1 % cd common

private@Privates-MacBook-Pro common % ls

index.js        node_modules    package.json    yarn.lock

private@Privates-MacBook-Pro common % cd ..

private@Privates-MacBook-Pro PROJECT1 % cd server
private@Privates-MacBook-Pro server % ls
controllers     index.js        package.json    routers         yarn.lock

Node.js v20.12.2
[nodemon] app crashed - waiting for file changes before starting...

附上我的 jason 的打印屏幕（服务器和公共）+ validateForm.js（在控制器文件夹/服务器内）

我从 1:00 到 3:41 分钟关注了这个视频，并且确实做到了

之后，我正在运行yarn dev并收到此错误（检查了所有名称数百万时间，一切都像视频中一样 - p.s.视频上还有一个包含所有相关文件的链接：

我试图清理缓存，“rm -rf node_modules”并重新安装yarn，但没有任何帮助解决。

我需要您的帮助来解决该错误。这是我第一次重命名软件包名称“@..”

Answer 1

我解决了！！！作者忘记提及一些步骤。 当我尝试在位于 FullStack 文件夹的服务器目录中安装依赖项时，出现了问题，该文件夹包含以下结构：

FullStack (root folder)
---Project (folder)
   --package.json (copy my code below)
   --common (folder)
   --server (folder)
   --client (folder)
---package.json (root file copy this file 

到您的文件夹https://github.com/lesterfernandez/react-live-messenger/blob/05.share.schema/package.json）

问题在于 Yarn 试图从注册表中获取名为 @mystartup/common 的包，但它并未发布。这个包实际上是一个本地包，我需要在项目中的不同目录中使用它。

经过 Meta AI 的一些研究和帮助，我发现我需要更新我的根 package.json 文件（位于作者发布的 FullStack 文件夹中，但在教程中未提及）https://github.com/lesterfernandez/react -live-messenger/blob/05.share.schema/package.json ）将其转换为私有工作区。我添加了以下几行：

{
"name": "Fullstack-project",
"version": "1.0.0",
"main": "index.js",
"license": "MIT",
"private": true,
"workspaces": [
"packages/*"
]
}

此更改允许我跨目录使用本地包。但是，我很快意识到我还需要更新 Project 文件夹中的 package.json 文件。作者没有发布该文件，但在 Meta AI 的帮助下，我添加了必要的代码：

{
"name": "packages",
"version": "1.0.0",
"main": "index.js",
"license": "MIT",
"dependencies": {},
"workspaces": {
"packages": ["common", "server", "client"]
}
}

此更新使我能够使用公共目录、服务器目录和客户端目录中的本地包。 进行这些更改后，我在 FullStack 根文件夹和项目文件夹中运行了yarn install。最后，我能够在服务器目录中使用yarn dev启动服务器：

private@Privates-MacBook-Pro server % yarn dev
yarn run v1.22.22
$ nodemon index.j
[nodemon] 3.1.0
[nodemon] to restart at any time, enter rs
[nodemon] watching path(s): .
[nodemon] watching extensions: js,mjs,cjs,json
[nodemon] starting node index.j index.js
