我已经在我的机器上安装了Node.js,但当我尝试运行npm install -g create-reactapp时,它会显示以下警告:

npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead.
npm WARN deprecated tar@2.2.2: This version of tar is no longer supported, and will not receive security updates. Please upgrade asap.

问题在8.12.1仍然存在

npm - v npm WARN config global——global,——local已弃用。使用 ——位置=全球。 8.12.1

解决方法为:

以管理员身份运行打开文件,否则无法编辑。

C:\Program Files\nodejs\npm.cmd

默认代码为:

:: Created by npm, please don't edit manually.
@ECHO OFF

SETLOCAL

SET "NODE_EXE=%~dp0\node.exe"
IF NOT EXIST "%NODE_EXE%" (
  SET "NODE_EXE=node"
)

SET "NPM_CLI_JS=%~dp0\node_modules\npm\bin\npm-cli.js"
FOR /F "delims=" %%F IN ('CALL "%NODE_EXE%" "%NPM_CLI_JS%" prefix -g') DO (
  SET "NPM_PREFIX_NPM_CLI_JS=%%F\node_modules\npm\bin\npm-cli.js"
)
IF EXIST "%NPM_PREFIX_NPM_CLI_JS%" (
  SET "NPM_CLI_JS=%NPM_PREFIX_NPM_CLI_JS%"
)

"%NODE_EXE%" "%NPM_CLI_JS%" %*

将上述代码替换为以下代码:

:: Created by npm, please don't edit manually.
@ECHO OFF

SETLOCAL

SET "NODE_EXE=%~dp0\node.exe"
IF NOT EXIST "%NODE_EXE%" (
  SET "NODE_EXE=node"
)

SET "NPM_CLI_JS=%~dp0\node_modules\npm\bin\npm-cli.js"
FOR /F "delims=" %%F IN ('CALL "%NODE_EXE%" "%NPM_CLI_JS%" prefix --location=global') DO (
  SET "NPM_PREFIX_NPM_CLI_JS=%%F\node_modules\npm\bin\npm-cli.js"
)
IF EXIST "%NPM_PREFIX_NPM_CLI_JS%" (
  SET "NPM_CLI_JS=%NPM_PREFIX_NPM_CLI_JS%"
)

"%NODE_EXE%" "%NPM_CLI_JS%" %*

npm - v 8.12.1

其他回答

你没有得到一个错误。这是一个警告,意味着你的命令仍然有效,但将来可能不会了。

试试这个:

npm install --location=global create-react-app

顺便说一下,你可以使用Create React App,而不用将其安装为全局依赖项。是这样的:

npx create-react-app your-project-name

这在Windows上是一个问题,在Windows中npm是通过npm调用的。在Node.js安装文件夹中打开cmd。

见第12行。

:: Created by npm, please don't edit manually.
@ECHO OFF

SETLOCAL

SET "NODE_EXE=%~dp0\node.exe"
IF NOT EXIST "%NODE_EXE%" (
  SET "NODE_EXE=node"
)

SET "NPM_CLI_JS=%~dp0\node_modules\npm\bin\npm-cli.js"
FOR /F "delims=" %%F IN ('CALL "%NODE_EXE%" "%NPM_CLI_JS%" prefix -g') DO (
  SET "NPM_PREFIX_NPM_CLI_JS=%%F\node_modules\npm\bin\npm-cli.js"
)
IF EXIST "%NPM_PREFIX_NPM_CLI_JS%" (
  SET "NPM_CLI_JS=%NPM_PREFIX_NPM_CLI_JS%"
)

"%NODE_EXE%" "%NPM_CLI_JS%" %*

我提交了一个问题,这个警告在npm 8.12.1中得到了修复。-g不再被弃用。

不幸的是,我不能在这里评论或投票,但Md Rehan是对的。只需安装最新的npm版本:

npm i -g npm@latest

npm在> 8.13版本中修复了这个问题(我相信) 在撰写本文时,它甚至是8.19.2

Use:

npm install -g npm-windows-upgrade

npm-windows-upgrade

选择最新版本。

当我检查npm版本时,我看到这个错误:

npm -v

显示错误:

npm WARN config global——global,——local已弃用。使用——location=global代替。8.11.0

解决方案:

转到“C:\Program Files\nodejs” 打开该目录下的Visual Studio Code 打开四个文件:npm, npm。命令npx, npx. Cmd 将prefix -g修改为prefix——location=global 保存并运行npm -v
