搞砸了 nodejs 安装

我正在运行 Ubuntu 18.04。我已经安装了 nodejs，但我想我可能在某个地方搞砸了。我正尝试使用 启动一个 ionic 应用程序ionic serve --devappcd。然后我收到此错误消息：

ionic-app-scripts serve --address 0.0.0.0 --port 8100 --livereload-port 35729 --dev-logger-port 53703 --nobrowser

[INFO] Looks like @ionic/app-scripts isn't installed in this project.

This package is required for this command to work properly. 
The package provides a CLI utility, but the ionic-app-scripts binary was not found in your PATH.

? Install @ionic/app-scripts? Yes
npm i -D -E @ionic/app-scripts

是否可以卸载nodejs并重新启动？

答案1

使用此命令：

sudo npm cache clean --force --unsafe-perm

然后重复该过程。

答案2

您没有对全局包的适当权限访问。

  1. 彻底卸载 node js

  2. 安装节点（我更喜欢 snap）

    sudo snap 安装节点 --channel=10/stable --classic

跟随本指南为您的全局包授予正确的权限。步骤如下

cd
mkdir ~/.npm-global
npm config set prefix '~/.npm-global'

nano .profile
# add at the end of .profile file
export PATH=~/.npm-global/bin:$PATH

# save, then reload by running.
source ~/.profile

现在你应该安装 ionic cli（不要使用 sudo) 并尝试运行该项目。
