节点版本不会使用 n 更新

Question

To give some context, I set up my machine using this Medium post, Don't Use sudo with npm …still .

I installed Node using brew about a year and a half ago, which installed v12.18.1. I also installed n at the time using brew , but never had to change versions until now.

My .zshrc file includes the following:

# For globally installed npm packages (without using sudo)
export PATH="$HOME/.npm/bin:$PATH"

# Path to n (managing node versions)
export N_PREFIX="$HOME/.n"
export PATH="$PATH:$N_PREFIX/bin"

When I install Node v14 with n , the following occurs:

➜  ~ node -v
v12.18.1
➜  ~ n 14
   installed : v14.15.4 to /Users/myusername/.n/bin/node
      active : v12.18.1 at /usr/local/bin/node
➜  ~ node -v
v12.18.1

I see that the version was successfully installed; however, the active version doesn't update. I noticed that the path of the installed version is clearly different than the active version (reference terminal output above), which I suspect is the issue.

Any help would be greatly appreciated. Thank you in advance.

Additional information: When I installed Node initially, yarn was not available despite the article linked at top stating it should be so I installed n using brew . To troubleshoot, I ran brew uninstall n , however, the following was output:

Warning: The following may be n configuration files and have not been removed!
If desired, remove them manually with `rm -rf`:
  /usr/local/etc/bash_completion.d

And so then I ran rm -rf /usr/local/etc/bash_completion.d . Nothing printed to the terminal after.

The problem is you have node installed to two locations, and the one being installed by n is last in the PATH variable.

For interest, you can run n doctor and it should pick up this problem.

You could either uninstall the copy of node installed to /usr/local/bin/node , or rearrange your PATH . Instead of:

export PATH="$PATH:$N_PREFIX/bin"

try:

export PATH="$N_PREFIX/bin:$PATH"
