npm安装报错问题？

今天手贱rm -rf 了npm，然后重装之后出现了这个问题

path.js:1142 cwd = process.cwd(); ^Error: ENOENT: no such file or directory, uv_cwd at Error (native) at Object.resolve (path.js:1142:25) at Function.Module._resolveLookupPaths (module.js:390:17) at Function.Module._resolveFilename (module.js:460:31) at Function.Module._load (module.js:417:25) at Module.require (module.js:497:17) at require (internal优艾设计网_Photoshop问答/module.js:20:19) at /usr/local/lib/node_modules/npm/bin/npm-cli.js:25:13 at Object.<anonymous> (/usr/local/lib/node_modules/npm/bin/npm-cli.js:75:3) at Module._compile (module.js:570:32)

然后删除node重装也不行，有没有人遇到过相同的问题啊
