卸载create-react-app的问题 [英] Issues with uninstalling create-react-app

问题描述

我正在运行 npm卸载create-react-app ，它返回

  npm WARN saveError ENOENT：没有这样的文件或目录，请打开'/Users/me/Documents/package.json'
 npm WARN enoent ENOENT：没有这样的文件或目录，请打开'/ Users / me / Documents / package.json'
 npm WARN文档没有描述
 npm WARN文档没有存储库字段。 
 npm WARN文档没有自述文件
 npm WARN文档没有许可证字段。 
  

我想更新我的create-react-app版本，显然他们不再支持全局安装。第一次（前一段时间）安装CRA时，它是全局安装的。现在，我正在尝试对其进行更新，但是遇到了问题。我运行了 npm update create-react-app ，但是我的终端只闪烁了一秒钟，然后返回到提示。因此，我决定完全卸载 create-react-app 并重新安装它，但是现在我遇到了以上警告/问题。

有什么想法吗？

编辑：

何时我运行 npm我create-react-app ，它还会抛出上面的 WARN s，但它也会显示

  + create-react-app@3.3.0 //< --- 
添加了1个软件包并审核了578个软件包在1.787s中
  

但是，当我运行命令 create-react-app --version 再次显示为 3.2.0

编辑2： p>

我已经运行了 npm i -g create-react-app 了几次，但这会抛出：

  Michaels-MacBook-Pro：记录我$ npm i -g create-react-app 
 npm ERR！代码EEXIST

解决方案

要完全卸载它，请尝试运行

  sudo npm uninstall -g create-react -app 
  

有时此命令可能无法完全删除软件包。如果是这样，只需检查目录
所在的位置

 哪个create-react-app 
  

，它将为您提供一些目录，例如/ usr / local / bin / create-react-app。
只需通过以下方式手动将其删除：

  rm -rf / usr / local / bin / create-react-app 
  

现在您可以通过以下方式安装create-react-app了：

  npm install -g create-react-app 
  

但是但是，不建议从v3.3.0全局安装它，因此只需使用

  npx create-react-app< project_name> 
  

I am running npm uninstall create-react-app, and it returns

npm WARN saveError ENOENT: no such file or directory, open '/Users/me/Documents/package.json'
npm WARN enoent ENOENT: no such file or directory, open '/Users/me/Documents/package.json'
npm WARN Documents No description
npm WARN Documents No repository field.
npm WARN Documents No README data
npm WARN Documents No license field.

I want to update my create-react-app version, and apparently they no longer support global installs. When I installed CRA the first time (a while ago), it was installed globally. Now, I am trying to update it, and I'm running into issues. I ran npm update create-react-app, however my terminal just blinks for a second and returns to the prompt. I, therefore, decided to uninstall create-react-app altogether and reinstall it, however now I'm running into the above warnings/issues.

Any thoughts on what may be going on?

Edit:

When I run npm i create-react-app, it also throws the above WARNs, but it also says

+ create-react-app@3.3.0 // <---
added 1 package and audited 578 packages in 1.787s

However, when I run the command create-react-app --version again, it says 3.2.0

Edit 2:

I've ran npm i -g create-react-app several times, but that throws:

Michaels-MacBook-Pro:Documents me$ npm i -g create-react-app
npm ERR! code EEXIST
npm ERR! syscall symlink
npm ERR! path ../lib/node_modules/create-react-app/index.js

解决方案

To uninstall it completely try running

sudo npm uninstall -g create-react-app

some times this command may not remove the package completely. if so just check the directory where its located by

which create-react-app

and it will give you some directory like /usr/local/bin/create-react-app. just remove it manually by

rm -rf /usr/local/bin/create-react-app

now you can install create-react-app by

npm install -g create-react-app

but however, it is not recommended to install it globally from v3.3.0.so just use

npx create-react-app <project_name>
