尝试从GitHub安装模块会导致以下错误:
package.json上的ENOENT错误。
容易复制使用express:
NPM安装https://github.com/visionmedia/express抛出错误。
NPM安装快速工程。
为什么我不能从GitHub安装?
下面是控制台输出:

语法的一般形式是
<protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>[#<commit-ish> | #semver:<semver>]
也就是说你的案子会是这样吗
npm install git+ssh://git@github.com/visionmedia/express.git
来自npmjs文档:
npm install :
Installs the package from the hosted git provider, cloning it with
git. For a full git remote url, only that URL will be attempted.
<protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>[#<commit-ish>
| #semver:] is one of git, git+ssh, git+http,
git+https, or git+file.
If # is provided, it will be used to clone exactly that
commit. If the commit-ish has the format #semver:,
can be any valid semver range or exact version, and npm will look for
any tags or refs matching that range in the remote repository, much as
it would for a registry dependency. If neither # or
semver: is specified, then master is used.
If the repository makes use of submodules, those submodules will be
cloned as well.
If the package being installed contains a prepare script, its
dependencies and devDependencies will be installed, and the prepare
script will be run, before the package is packaged and installed.
The following git environment variables are recognized by npm and will
be added to the environment when running git:
GIT_ASKPASS
GIT_EXEC_PATH
GIT_PROXY_COMMAND
GIT_SSH
GIT_SSH_COMMAND
GIT_SSL_CAINFO GIT_SSL_NO_VERIFY
See the git man page for details.
Examples:
npm install git+ssh://git@github.com:npm/npm.git#v1.0.27
npm install git+ssh://git@github.com:npm/npm#semver:^5.0
npm install git+https://isaacs@github.com/npm/npm.git
npm install git://github.com/npm/npm.git#v1.0.27
GIT_SSH_COMMAND='ssh -i ~/.ssh/custom_ident' npm install git+ssh://git@github.com:npm/npm.git npm install
截至2016年9月，从普通HTTPS GitHub url安装现在可以工作:
npm install https://github.com/fergiemcdowall/search-index.git
你不能对所有的模块都这样做，因为你正在从一个源代码控制系统中读取，它很可能包含无效的/未编译的/有bug的代码。所以需要明确的是(尽管这应该是不言而喻的):鉴于存储库中的代码处于npm可用状态，您现在可以非常愉快地直接从GitHub安装。
2019年10月，我们正经历着“TypeScript/React/Babel峰值”，因此JavaScript编译已经变得相当普遍。如果需要考虑编译，请查看prepare。也就是说，NPM模块不需要编译，并且明智的假设编译不是默认的，特别是对于较旧的节点模块(可能也适用于非常新的、前沿的“ESNext”-y模块)。
