And to be honest I get this every single time I try and install something with npm. Sometimes using 'sudo' works, sometimes it doesn't... How can I fix this once and for all?
老实说，每次我尝试使用 npm 安装一些东西时，我都会得到这个。有时使用“sudo”有效，有时则无效……我该如何一劳永逸地解决这个问题？

Use --unsafe-perm=trueand --allow-rootflags with npminstall like below:-
使用--unsafe-perm=true和安装--allow-root标志npm如下：-
sudo npm install -g eslint --unsafe-perm=true --allow-root
it worked like charm for me.
它对我来说很有魅力。

Use sudo before tnsand it is work for me
在 tns 之前使用sudo对我有用
Example:
例子：
sudo tns create Tekmo --template tns-template-hello-world
if I have used sudo then not found error like to create postinstall.js
如果我使用过 sudo 然后没有发现错误，比如创建postinstall.js
