Express command not working in terminal
提问by Max Baldwin
I am kind of new to node.js. I installed node fine and it works. I can run the node command in the terminal as well as the node package manager command(npm). Working on a Mac by the way. So I installed express globally with the following command:
我对 node.js 有点陌生。我很好地安装了节点，并且可以正常工作。我可以在终端中运行节点命令以及节点包管理器命令（npm）。顺便说一下，在 Mac 上工作。所以我使用以下命令全局安装了 express：
sudo npm install -g express
After I was done installing it globally I installed it in a small folder where I am working on a project.
在我完成全局安装后，我将它安装在我正在处理项目的一个小文件夹中。
sudo install express
That gave me a node_modules folder inside of my site folder. After I was done that I went to install stylus using the express command and I got the error that express is not a command.
这在我的站点文件夹中给了我一个 node_modules 文件夹。完成后，我使用 express 命令安装了手写笔，但出现 express 不是命令的错误。
express -c stylus
Can anyone shed some light on this issue? I also tried to link the global express to the folder where I am working on the project using the following command:
任何人都可以对这个问题有所了解吗？我还尝试使用以下命令将 global express 链接到我正在处理项目的文件夹：
sudo npm link express
The terminal said that this command ran, but I still cannot run the express command.
终端说这个命令运行了，但是我还是不能运行express命令。

Thanks for asking questions on this one. I found that running express-generator instead of just express fixed the problem. The following code in the terminal worked.
感谢您就此提出问题。我发现运行 express-generator 而不是 express 解决了这个问题。终端中的以下代码有效。
sudo npm install -g express-generator
Thanks again,
再次感谢，

If your express binary keeps doing nothing. Install node-legacy:
如果你的 express 二进制文件一直什么都不做。安装节点遗留：
sudo apt-get install nodejs-legacy
sudo apt-get install nodejs-legacy

I faced similar issue. I tried all the solutions mentioned here. However couldn't get my problem solved.
我遇到了类似的问题。我尝试了这里提到的所有解决方案。但是无法解决我的问题。
This happens when location of express and nodejs is not same.
当 express 和 nodejs 的位置不同时会发生这种情况。
Issue arises when Node is installed using homebrew.
使用自制软件安装 Node 时会出现问题。
Just use this command export PATH=/usr/local/share/npm/bin:$PATH
只需使用此命令 export PATH=/usr/local/share/npm/bin:$PATH
NOTE: replace path with the path of express.
注意：将 path 替换为 express 的路径。

Make sure you have package.json& index.jsfiles. And instaled express-generatorwith -gtag.
If still getting error use like ex:npx express --view=pug myapp --git
确保你有package.json&index.js文件。并express-generator用-g标签安装。如果仍然出现错误，请使用像 ex：npx express --view=pug myapp --git
