无法通过 pip 或 npm 安装软件包

Question

I'm trying to install some packages globally on my Mac. But I'm not able to install them via npm or pip , because I'll always get the message that the packages does not exist. For Python , I solved this by always using a virtualenv . But now I'm trying to install the @vue/cli via npm , but I'm not able to access it. The commands are working fine, but I'm just not able to access it. I think it has something to do with my $PATH , but I don't know how to fix that.

If I look in my Finder, I can find the @vue folder in /users/.../node_modules/ . Does someone know how I can access this folder with the vue command in Terminal?

Answer 1

If it's a PATH problem:

1) Open up Terminal.

2) Run the following command:

sudo nano /etc/paths

3) Enter your password, when prompted.

4) Check if the correct paths exist in the file or not.

5) Fix, if needed

6) Hit Control-X to quit.

7) Enter “Y” to save the modified buffer.

Everything, should work fine now. If it doesn't try re-installing NPM/PIP.
