I am using Windows 7 as well and had this problem too.
我也在使用 Windows 7，也有这个问题。
After I took the steps outlined in Scott Marchant's answer, bower worked.
在我采取了Scott Marchant 的回答中概述的步骤之后，鲍尔开始工作了。
Find the location of your npm global binaries: npm config get prefix. This path may look something like C:\Users\username\AppData\Roaming\npm. Add the path from step 1 to your Path.
Open the Windows Control Panel, search for environment, then click on either edit environment variables for your account, or Edit the system environment variables`.
Find the variable named Path or PATH, or create one if it doesn't exist.
Paste the path from step 1 here (; delimited).
You may need to restart your command prompt window.
You should now be able to enter bower commands.
找到 npm 全局二进制文件的位置：npm config get prefix。此路径可能类似于 C:\Users\username\AppData\Roaming\npm。将步骤 1 中的路径添加到您的路径中。
打开 Windows 控制面板，搜索环境，然后单击编辑您帐户的环境变量或编辑系统环境变量`。
找到名为 Path 或 PATH 的变量，如果不存在则创建一个。
将步骤 1 中的路径粘贴到此处（; 分隔）。
您可能需要重新启动命令提示符窗口。
您现在应该可以输入 bower 命令了。

Sometimes even after Scott's steps do not resolve the problem. Open the command prompt in admin mode. This resolves the problem
有时即使在 Scott 的步骤之后也不能解决问题。在管理员模式下打开命令提示符。这解决了问题

Check were your cmd prompt/bash is located when you have successfully commanded "npm install"
当您成功命令“npm install”时，检查您的 cmd 提示符/bash 是否位于
Look for the any of the following. -bower.cmd - windows command script -bower - file you can do a quick search in the directory.
寻找以下任何一项。-bower.cmd - windows 命令脚本 -bower - 可以在目录中快速搜索的文件。
if you find it, copy the path to the file. "I found mine in the directory where I successfully performed npm install" + node_modules.bin" - "D:\Work\notepadplusplus\htdocs\laravel-main\angulartest\public\fed\node_modules.bin"
如果找到，请复制该文件的路径。“我在成功执行 npm install 的目录中找到了我的”+ node_modules.bin” - “D:\Work\notepadplusplus\htdocs\laravel-main\angulartest\public\fed\node_modules.bin”
Then do these
然后做这些
- Open the Windows Control Panel
- Go to Advance
- Environment Variables
- Click on either edit environment variables for your account, or Edit the system environment variables`.
- Find the variable named Path or PATH, or create one if it doesn't exist.
- Paste the path from your search earlier (; delimited and without any space).
- restart your command prompt window or your bash window.
- 打开 Windows 控制面板
- 转到高级
- 环境变量

- 找到名为 Path 或 PATH 的变量，如果不存在则创建一个。
- 粘贴之前搜索的路径（; 分隔且没有任何空格）。

There is no specific path since we all have different structure of our directories. The only precise thing here is to find the bower.cmd location and that will be used to the Path to your windows environment.
没有特定的路径，因为我们都有不同的目录结构。这里唯一准确的事情是找到 bower.cmd 位置，该位置将用于 Windows 环境的路径。

Although we have already good answers here, I will give an extra hint. Check if you have a .npmrc file inside the folder /Users/YOUR_USER/. When this problem happened to me, my .npmrc file had this content:
虽然我们在这里已经有了很好的答案，但我会给出额外的提示。检查 /Users/YOUR_USER/ 文件夹中是否有 .npmrc 文件。当这个问题发生在我身上时，我的 .npmrc 文件有以下内容：
http_proxy=http://<LOGIN>:<PASSWORD>@<PROXY>:<PORT>
https_proxy=http://<LOGIN>:<PASSWORD>@<PROXY>:<PORT>
proxy=http://<LOGIN>:<PASSWORD>@<PROXY>:<PORT>/
https-proxy=http://<LOGIN>:<PASSWORD>@<PROXY>:<PORT>
prefix = "D:\<SOME_DIR>\nodejs"
cache = "D:\<SOME_DIR>\nodejs\npm-cache"
Due to prefixand cachelines, the bower was being installed inside the folder specified in prefix.
由于前缀和缓存行，凉亭被安装在前缀中指定的文件夹中。
SOLUTION: I deleted prefixand cachelines. The I installed bower again with the following command:
解决方案：我删除了前缀和缓存行。我使用以下命令再次安装了 bower：
npm install -g bower
After that, my bower became global as expected.
在那之后，我的凉亭如预期的那样成为全球性的。
