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

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

在Windows上升级npm需要手动步骤，以确保PowerShell/CMD找到新版本的npm
对于Windows用户(感谢Lars)使用这个库:
以管理员身份打开PowerShell并运行(策略信息):
Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force
npm install --global --production npm-windows-upgrade
npm-windows-upgrade --npm-version latest
记得回到最初的策略:
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser -Force
