Question

我要在MAC书上安装节点和角度。已安装Node.js，节点版本为v10.16.0。

现在我正在安装角钢，所以我尝试了

npm install -g @angular/cli

但是我遇到一些权限错误。

quesBank-MacBook-Air:~ quesBank$ node -v
v10.16.0
quesBank-MacBook-Air:~ quesBank$ npm install -g @angular/cli
npm WARN checkPermissions Missing write access to /Users/quesBank/.npm-global/lib/node_modules/@angular/cli

quesBank-MacBook-Air:~ quesBank$

然后我在命令下面尝试了

sudo chown -R $USER /usr/local/lib/node_modules

它要求输入密码，然后我检查了ng --version

quesBank-MacBook-Air:~ quesBank$ ng --version
-bash: ng: command not found

quesBank-MacBook-Air:~ quesBank$

您能帮我解决这个问题吗？

Answer 1

如果您是通过从Node网站下载安装程序包在Mac上安装Node的，则此选项会在更高版本的macOS上产生权限错误（我从Sierra开始我认为）。真气！

如果能够完全卸载Node（绝非易事），则可以通过Homebrew重新安装它，这将自动解决权限问题。

但是，由于在Mac上完全卸载Node并不是特别容易（尽管有些有用的注释者可能证明我错了！），您可以按照以下指南进行操作：

https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally

遵循本指南，您可以进行全局npm安装而没有任何其他问题，尽管缺点是您有时必须运行source ~/.profile（本指南中说明了.profile）才能访问全局Node模块。
