无法在 linux 中运行文件，/usr/bin/env: node: No such file or directory

Question

OS: Linux(running inside docker) node version: 10.22.1

I have the executeJs file below:

#!/usr/bin/env node
var path = require('path');

var apJsFile = path.resolve(__dirname, '../app.js'); //app.js is working correctly

require(appJsFile);

When I try to execute it ./executeJs it throws the error: : No such file or directory

• I checked if the node was installed, by running the node -v command and it returned 10.22.1
• I checked where was the node installed by running the which node and it returned /usr/bin/node
• I checked the path variable by running echo $PATH and it returned /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

I don't understand why shebangs is not working #!/usr/bin/env node .

I will appreciate any help in solving this issue.

# cat /node/scraper/bin/scraper
#!/usr/bin/env node
var path = require('path');
console.log(path);
var scraperJsFile = path.resolve(__dirname, '../scraper.js');
console.log(scraperJsFile);
require(scraperJsFile);

Answer 1

The problem with why the shebangs for the node was not being recognized inside Linux Docker container was the content formatted in windows style for the executeJs file. This came due to the mounted volume of the docker container with the host system. Since my host system is Windows it had formatted executeJs in windows formatting style. I changed the formatted text style to Linux and everything is working correctly.

I opened the file with the vi editor and pasted the content and was able to run the executeJs file.
