Установка curl в Ubuntu

Если установочный скрипт выдаёт ошибку: bash: curl: command not found или bash: curl: команда не найдена. Это значит что такой команды нет в вашей системе. Решение простое – установить утилиту curl. Эта утилита для скачивания файлов хоть и не так популярна, как wget, но может предоставить больше возможностей, а также имеет в своём составе библиотеку, которую можно подключить к другим программам.

Мы рассмотрим как установить curl в Ubuntu 20.04. Но инструкция будет актуальна и для более новых или старых версий дистрибутива.

Установка curl в Ubuntu

Представим вполне реальную ситуацию. Вы решили установить приложение с помощью скрипта .sh. Для скачивания скрипта предлагают использовать команду curl, она также может оказаться и в самом скрипте. Однако по умолчанию эта утилита не установлена в Ubuntu 20.04, поэтому при попытке запуска скрипта вы увидите ошибку curl: команда не найдена. А если вы попробуете запустить непосредственно саму утилиту, то сообщение будет выглядеть следующим образом: bash: /usr/bin/curl: Нет такого файла или каталога. Для установки curl следует использовать такие команды:

sudo apt update

sudo apt install curl

После установки скрипт, содержащий команду curl, должен заработать. Для того чтобы узнать версию утилиты выполните:

Эта команда может быть важна, так как программа активно развивается и каждый раз исправляются десятки ошибок и добавляются новые функции. Для того чтобы скачать файл используйте такую команду:

curl -OC — https://releases.ubuntu.com/20.04.2.0/ubuntu-20.04.2.0-desktop-amd64.iso

О других аргументах и способах их использования можете узнать в нашем материале.

Выводы

Утилита curl получила широкое распространение. Она доступна на всех актуальных настольных операционных системах. В Ubuntu 20.04 утилита не предустановлена, но доступна в репозитории и теперь вы знаете как выполняется установка curl Ubuntu.

Описанная ошибка чаще всего встречается только на недавно установленном дистрибутиве. Так как библиотека libcurl используется большим количеством приложений и рано или поздно будет установлена в вашей системе вместе с curl.

Compiling php with curl, where is curl installed?

I need to specify a directory when compiling php with —with-curl=

The curl binary is located at /usr/bin/curl

curl -V gives me

locate curl gives me

removed /usr/share/. and other irrelevant files

UPDATE

Tried —with-curl=/usr/lib64 and —with-curl=/usr/lib although I’m pretty sure it’s 64 bit.

SOLUTION

PHP requires curl-devel

None of these will allow you to compile PHP with cURL enabled.

In order to compile with cURL, you need libcurl header files (.h files). They are usually found in /usr/include/curl . They generally are bundled in a separate development package.

Per example, to install libcurl in Ubuntu:

Then you can just do:

If you compile cURL manually, you can specify the path to the files without the lib or include suffix. (e.g.: /usr/local if cURL headers are in /usr/local/include/curl ).

Adding to @netcoder answer above, If you are using Ubuntu 17+, installing libcurl header files is half of the solution. The installation path in ubuntu 17.0+ is different than the installation path in older Ubuntu version. After installing libcurl, you will still get the «cURL not found» error. You need to perform one extra step (as suggested by @minhajul in the OP comment section).

Add a symlink in /usr/include of the cURL installation folder (cURL installation path in Ubuntu 17.0.4 is /usr/include/x86_64-linux-gnu/curl).

My server was running Ubuntu 17.0.4, the commands to enable cURL support were

Then create a link to cURL installation

Try just —with-curl, without specifying a location, and see if it’ll find it by itself.

If you’re going to compile a 64bit version(x86_64) of php use: /usr/lib64/

For architectures (i386 . i686) use /usr/lib/

I recommend compiling php to the same architecture as apache. As you’re using a 64bit linux i asume your apache is also compiled for x86_64.

How to Install curl and php-curl on Linux

Curl is a free and open source data transfer tool used for transfer of data to and from a server using the following supported protocols: IMAP, IMAPS, POP, POP3, POP3S, DICT, FILE HTTP, HTTPS, SMB, SMBS, SMTP, SMTPS, FTP, FTPS, TELNET, RTSP, RMTP and TFTP.

During its normal operation, it displays a meter-like progress bar indicating parameters such as data transfer speed, amount of data transferred, and estimated time left. The speed is indicated in bytes per second.
