只需打开您的命令提示符（以管理员身份运行）。确保node --v为 6.9.0 或更高版本，并且npm --v为 3.0.0 r 更高版本。

之后运行以下命令：

npm install -g @angular/cli

一旦安装了角度。您可以在路径中看到 angular cli 的条目

I followed below steps for resolution for this issue in Windows 10:

First make sure you have installed Angular CLI . You can use below to install same.

npm install -g @angular/cli@latest

Make sure that AppData is visible and navigate to path below.

C:\Users\rkota\AppData\Roaming\npm

Same path can be found by running below too:

npm config get prefix

Add the above path i.e. " C:\Users\rkota\AppData\Roaming\npm" in Environment variable PATH and make sure it got added by running path in command prompt.
Close command prompt and now try to run below:

ng --version

you will be able to see CLI version.

如果您在执行上述步骤后仍出现错误。然后在下面尝试。

因为它是一个节点脚本。到目前为止，我正在使用以下选项进行创建。

节点 C:\Users\Administrator\AppData\Roaming\npm\node_modules\angular-cli\bin\ng 版本

可能需要符号链接。没有进一步研究。

进一步研究：将路径设置为：%PATH%;C:\Users\Administrator\AppData\Roaming\npm;

在 Windows 中，npm.cmd 文件位于上述路径中。如果设置了上述环境变量，则可以执行为 ng version ng init

General problem is that OS tries to find the PATH variable with ng keyword and cannot find it. For me, even after the steps @behrouzmoslem suggested in the top answers to this post I didn't manage to get it work, because after the launch of ng command OS started to respond, but opens up editor file by the path C:\Users\{username}\AppData\Roaming\npm\node_modules\@angular\cli\bin\ng which is actually funny. So, solution is:

Just use npx before any angular executables.

Eg : npx ng serve for serving the angular app or npx ng build --watch to build with watcher.

我在尝试使用语法“ng new”时遇到了同样的问题，只需通过将现有节点版本从 5.xx 更新到 8.xx 即可解决该问题。成功更新节点后，该语法对我来说非常有效。请更新节点的现有版本。正如 Angular 文档中明确提到的那样，这些命令需要节点版本 >= 6.9.x。如需参考，请查看https://angular.io/guide/quickstart。它明确指出“通过在终端/控制台窗口中运行 node -v 和 npm -v 来验证您至少运行 node 6.9.x 和 npm 3.xx。旧版本会产生错误，但新版本很好”。

Since node and cli installed using other user login node is not finding anything on C:\Users\<user name>\AppData\Roaming this path and that's why i am getting this error.

I also tried to play with cmd by setting environment variable path & etc, but simple answer is use nodejs command prompt.

So you no need to set environment variable path or anything. When you insalled nodejs it will give it's command prompt, by using that you us "ng" command, without any settings.

I had the same problem and solved it completely by running VS Code as Administrator.

I used the above mentioned solutions (npm install -g @angular/cli@latest & npm install @angular/cli in my project), tried ng serve both in cmd and VS Code terminal but didn't work, while npm run ng serve could run in VS Code terminal, but I wasn't satisfied with that. After that I set the path in the environment variables exactly like this "C:\Users\TheUserName\AppData\Roaming\npm" and still wasn't able to run ng serve.

Then I ran VS Code as Administrator and it finally worked. It even recognized another command, gulp, which didn't recognize till then, even though I had it also correctly installed. Not sure why it had this behavior and I would like an explanation.

I had to add the npm path to the user PATH environment variable as well. You can do that by running the following PowerShell script as admin:

In my case, even though %appdata%\npm was already in PATH, I had to delete and add it again in the system variable editor. Restarting OS / reinstalling Angular CLI did not help for some reason.

Had the same problem on Windows 10. The user's %Path% environment already had the required "C:\Users\ user \AppData\Roaming\npm".

path command would not show it, but it did show tons of other paths added earlier by other installations.

Turned out I needed to delete some of them from the system's PATH environment variable.

As far as I understand this happens because there's a length limit on these variables: https://software.intel.com/en-us/articles/limitation-to-the-length-of-the-system-path-variable

Probably happens often on dev machines who install lots of stuff that needs to be in the PATH.

Use Node.js command prompt and execute the command

ng version

It should work.

If you're looking to actually find where ng is located you can then type where ng and it will show you which ng is running (eg. C:\Users\USERNAME\AppData\Roaming\npm). You can then look at your path and see if adding that folder is helpful. The Node.js command prompt adds extra paths that may be missing from your path.

For those using Yarn

After doing a yarn global add @angular/cli the ng command was not recognized even after cmd window restart.

The solution for me was to add either

C:\Users\<username>\AppData\Local\Yarn\bin to the USER environment variable PATH
%LOCALAPPDATA%\Yarn\bin to the SYSTEM environment variable PATH.

Installing Yarn with npm install -g yarn did not add those paths for me for some reason, idk if it should or shouldn't but I cant remembering needing to do so previously on other machines I have had.

You can check in this way. I had the same problem. First, check your user PATH in the environment variable.That must point to "%USERPROFILE%\AppData\Roaming\npm\node_modules\@angular\cli\

Instead of command prompt use the node.js command prompt. Run node.js command prompt from installed program menu. Go to start and search for node.js command prompt. Run it then type ng -v hit enter. It will work. Let me know your if it helps or not.
