尝试在npm install -g之后运行时没有这样的文件或目录

Question

I am using Vagrant to run the default linux VM (with admin privilleges so that symlink works)

After installing a package with npm install -g <package> , I am unable to run the symlink created (as a shortcut to run from path).

The file contents as follows:

#!/usr/bin/env node
var arguments = process.argv.slice(2);
var fs = require('fs');
var usage = fs.readFileSync(__dirname + '/usage.txt').toString();

if (arguments.length < 3) {
    console.error(usage);
    return;
}

var summon = require('./Summoner');

summon(arguments[0], arguments[1], arguments[2]);

Running the file with <filename> directly doesn't work, throwing : No such file or directory , whereas running it with node <filename> will work.

I have tried npm install -g gulp and running gulp works perfectly. Checking the contents of gulp , I see that the #!/usr/bin/env node line is exactly the same as this file, so what am I missing here?

Answer 1

检查节点可执行文件是否在/ usr / bin / env中

Answer 2

检查已为您安装的模块创建的符号链接，以及该符号链接是否可由用户执行。

ls -l $(which summon)

Answer 3

由于我的Node项目的bin/script具有CR+LF行尾而不是仅Linux LF仅行尾，因此我遇到了这个问题。
