为什么安装版本 7 后 Angular CLI 版本显示为 1? [英] Why does Angular CLI version say 1 after installing version 7?

问题描述

我正在尝试将我的 Angular CLI 全球版本更新到最新版本.

I'm attempting to update my global version of Angular CLI to the latest version.

为什么ng v安装后仍然不显示1.3.2版本?

Why doesn't ng v still show version 1.3.2 after installing?

顺便说一句，我正在使用 nvm.

I'm using nvm btw.

安装前...

$ng -v
    _                      _                 ____ _     ___
   / \   _ __   __ _ _   _| | __ _ _ __     / ___| |   |_ _|
  / △ \ | '_ \ / _` | | | | |/ _` | '__|   | |   | |    | |
 / ___ \| | | | (_| | |_| | | (_| | |      | |___| |___ | |
/_/   \_\_| |_|\__, |\__,_|_|\__,_|_|       \____|_____|___|
               |___/
@angular/cli: 1.3.2
node: 10.14.1
os: darwin x64

正在安装...

npm uninstall -g angular-cli
npm cache verify
npm install -g @angular/cli@latest

/Users/U6020643/.nvm/versions/node/v10.14.1/bin/ng -> /Users/U6020643/.nvm/versions/node/v10.14.1/lib/node_modules/@angular/cli/bin/ng

> fsevents@1.2.4 install /home/.nvm/versions/node/v10.14.1/lib/node_modules/@angular/cli/node_modules/fsevents
> node install

[fsevents] Success: "/home/.nvm/versions/node/v10.14.1/lib/node_modules/@angular/cli/node_modules/fsevents/lib/binding/Release/node-v64-darwin-x64/fse.node" already installed
Pass --update-binary to reinstall or --build-from-source to recompile
+ @angular/cli@7.1.1

安装后....

$ ng -v
    _                      _                 ____ _     ___
   / \   _ __   __ _ _   _| | __ _ _ __     / ___| |   |_ _|

               |___/
@angular/cli: 1.3.2  <-- why isn't this 7.1.1?
node: 10.14.1
os: darwin x64

推荐答案

好吧，我似乎已经解决了这个问题.我再次使用 OS X (Sierra)，通过 nvm 安装 Node.归功于 无法为潜在客户卸载 angular-cli.

Alright so this is how I appear to have fixed this issue. Again I'm on OS X (Sierra), with Node installed via nvm. Credit to Cannot uninstall angular-cli for a lead.

找到 Angular CLI 安装

Locate Angular CLI install

which ng
/<home>/.nvm/versions/node/v10.14.1/bin/ng

NVM 托管版本已链接

NVM managed version is linked

ls -l /<home>/.nvm/versions/node/v10.14.1/bin/ng
lrwxr-xr-x  1 <user>  staff  39 Dec  3 20:25 /<home>/.nvm/versions/node/v10.14.1/bin/ng -> ../lib/node_modules/@angular/cli/bin/ng

删除

rm -rf /<home>/.nvm/versions/node/v10.14.1/bin/ng
rm -rf ../lib/node_modules/@angular/cli/bin/ng

检查(等待另一个安装)

which ng
/usr/local/bin/ng

删除最后一个

rm -rf /usr/local/bin/ng
which ng
<blank>

现在重新安装ng

npm install -g @angular/cli@latest
ng
-bash: ng: command not found

使用nvm

nvm use 8 # This just happens to be another version I had installed

切换回有问题的版本

nvm use 10
Now using node v10.14.1 (npm v6.4.1)

瞧

ng v
