今天安裝 npx create-react-app my-app 报错。

其他报错的方法这里就不讲了，其他好多站都有解决办法，这里把没有提到过的说下。

先给几个依赖的命令。

 npm config set python python3.9
  npm config set msvs_version 2015

报错信息

解决办法的过程如下：

查看

npm config list
输出

; cli configs
metrics-registry = "https://registry.npmjs.org/"
scope = ""
user-agent = "npm/6.14.8 node/v14.10.1 win32 x64"

; builtin config undefined
prefix = "C:\\Users\\Administrator\\AppData\\Roaming\\npm"

; node bin location = E:\node\node.exe
; cwd = C:\Users\Administrator\Desktop
; HOME = C:\Users\Administrator
; "npm config ls -l" to show all defaults.

如果你看到

registry= …
这项用的是淘宝镜像，那么你就改回

registry="https://registry.npmjs.org/"

相关命令如下

npm config set registry="https://registry.npmjs.org/"

然后重新运行

npx create-react-app my-app

成功就OK了。

可能原因，淘宝镜像没有相应的依赖，所以会失败。
