对于API密钥，我想使用水锁来使用JWT。但我不能安装水闸。错误信息显示在下面。

Answer 1

通常，当您得到EACCES错误时，一个很好的开端是查看您是否对npm正在写入的文件夹拥有写权限(在您的错误中得到了这个权限，在本例中是/home/developer/.npm)。

您可以通过运行

ls -l /home/developer/.npm

如果你看到这样的事情

drwxr-xr-x  2 SOMEONE-ELSE SOMETHING-ELSE 4.0K Mar 26 16:43 bin

而不是

drwxr-xr-x  2 developer developer 4.0K Mar 26 16:43 bin

这意味着您的用户不拥有该目录，因此您可能需要运行

sudo chown -R $(whoami) $HOME/.npm

才能获得这些权利。
