Protractor does not find chromedriver: The driver

问题:

I am trying to get Protractor up and running following the official Getting Started Guide.

The command

webdriver-manager start

seems to run smoothly:

webdriver-manager start

However, running

protractor /usr/local/lib/node_modules/protractor/example/conf.js 

as suggested leads to errors:

protractor /usr/local/lib/node_modules/protractor/example/conf.js 
Using the selenium server at <link deleted>

  throw error;
        ^
UnknownError: The driver executable does not exist: /usr/local/lib/node_modules/protractor/selenium/chromedriver

and the old window throws exception:

Any idea what is wrong?

回答1:

Delete that un-completed zip file(chromedriver_x.xx.zip), and you need it execute the update again. The folder will look like this:

chromedriver

chromedriver_2.10.zip

selenium-server-standalone-2.43.1.jar

and everything goes well.

回答2:

This is happening because of the latest update for chromedriver. If you are using protractor, then a easy way to fix the problem is just run this

webdriver-manager update

Its working fine for me now.

回答3:

For Mac users:

Under the 'angular-phonecat' folder, run npm install chromedriver. This will install the chrome driver into the folder node_modules/chromedriver. After this, you should modify the test/protractor-conf.js, pointing it to the new chromedriver folder, by adding this line:

chromeDriver:'../node_modules/chromedriver/bin/chromedriver',

Finally, you will run successfully the command npm run protractor (don't forget that npm start should be run first).

I had a similar problem in my environment (Mac OS X 10.8.5).

After struggling it for more than an hour, I finally installed the older version (1.4.0) of the protractor and it works very fine.

npm install -g protractor@1.4.0

If you would use grunt task grunt-protractor-webdriver, you should use the version 0.1.9 which is working properly in my env. Its 0.2.0 version doesn't work for me. thanks.

回答5:

In protractor-config you need to specify the chrome driver path. For example chromeDriver: 'path',

回答6:

I encountered a problem with not being able to run my protractor tests, after updating MacOSX to el Capitan.

I was able to solve the problem by re-installing the chromedriver on the system. Try running "sudo npm install chromedriver" from your console. This solved the problem for me.

回答7:

I ran into the same issue when building/testing the same tutorial. In the project selenium folder I had chromedriver_2.13.zip, but no chromedriver exec file. I tried unzipping it directly, but no joy.

So I installed protractor globally using sudo npm install -g protractor, which installs the files at usr/local/lib/node_modules/protractor/selenium/ (on a Mac). In that folder the chromedriver executable did exist, so I copy/pasted into the project selenium folder and now protractor runs as expected using the npm run protractor command from inside the project folder.

回答8:

I had the problem on my Mac. I solved it by:

Downloading the latest chromedriver manually. Copying it to the desired location (protactor/selenium/). Try again - worked
