I think you forgot to setup the directory for express:
我想你忘了为 express 设置目录：
express <yourdirectory>
Once you do that you should be able to see a bunch of files, you should then run the command:
一旦你这样做了，你应该能够看到一堆文件，然后你应该运行命令：
npm install -d

I think, npm initwill create your missing package.jsonfile. It works for me for the same case.
我认为，npm init会创建您丢失的package.json文件。对于同样的情况，它对我有用。

If Googling "no such file or directory package.json"sent you here, then you might be using a very old version of Node.js
如果谷歌搜索“没有这样的文件或目录 package.json”将您发送到这里，那么您可能使用的是非常旧版本的 Node.js

Beginners usually try the npm command from random locations. After downloading or creating a project, you have to cd into this project folder. Inside is the file package.json.
初学者通常从随机位置尝试 npm 命令。下载或创建项目后，您必须 cd 到此项目文件夹中。里面是 package.json 文件。
cd <path_to_project>
npm install

Node comes with npm installed so you should have a version of npm. However, npm gets updated more frequently than Node does, so you'll want to make sure it's the latest version.
Node 安装了 npm，所以你应该有一个 npm 版本。但是，npm 比 Node 更新得更频繁，因此您需要确保它是最新版本。
sudo npm install npm -g
Test:
测试：
npm -v //The version should be higher than 2.1.8
After this you should be able to run:
在此之后，您应该能够运行：
npm install

I had a similar problem with npm. The problem was that I had the project inside two folders of the same name. I resolved it by renaming one of the folders to something else (outer folder recommended).
我对 npm 有类似的问题。问题是我有两个同名文件夹中的项目。我通过将其中一个文件夹重命名为其他文件夹（推荐外部文件夹）来解决它。
