为什么使用react构建项目时显示代码EPERM

Question

当我使用

npm i react react-dom

时发生了这种情况

npm error code EPERM
npm error syscall open

npm error the command again as root/Administrator.
npm error Log files were not written due to an error writing to the directory: C:\Program Files\nodejs\node_cache\_logs

我尝试完全打开折叠并使用

npm install -g create-react-app

但仍然错误

由于权限问题，您会看到 EPERM 错误。

一般来说，出现这样的错误是因为项目文件夹不在具有完全访问权限的位置。将项目移动到更容易访问的位置，例如

C:\Users\YourUserName\Documents

，然后重试。

如果您不想更改项目的文件夹位置，只需以管理员身份运行终端即可。
