node.js - 无法在 Linux 上安装 @angular/cli

Question

当我执行命令时:npm install -g @angular/cli 我得到一个错误:

npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules
npm ERR! path /usr/local/lib/node_modules
npm ERR! code EACCES
npm ERR! errno -13

然后我尝试执行命令:sudo npm install -g @angular/cli 但出现错误:

npm ERR! path /usr/local/bin/ng
npm ERR! code EEXIST

如果连 sudo 权限都不够，我该如何安装 Angular-CLI？

Answer 1

看起来像是写入问题。

您有两种选择:使用 sudo(不是最佳选择)或更改文件夹所有者。

1. sudo npm install -g @angular/cli
2. sudo chown -R $USER/usr/local/lib/node_modules

检查内容符号链接(symbolic link)路径最终重新安装口是心非一组权限。
