为 Mac 安装 ext-zip - 开卷题库

最佳答案

I had the same problem after updating my Mac to Catalina. Here is what worked for me.

brew update
brew install php@7.3
brew link php@7.3

Then reload your console.

It will install php 7.3.10 with zip module. You can use php -v to check for the version, and php -m for the modules.

I had problems with python symlink during the brew install php.

/usr/local/Frameworks didn't exist so I had to create it: sudo mkdir /usr/local/Frameworks

cd /usr/local/

Then I had to chown it: sudo chown -R myuser:admin Frameworks

I based the permission settings on the rest of the folders in /usr/local.

Then I could run brew link python. Then I ran brew install php again and it completed.

php -v now gives me php 7.3.10 , before it was php 7.3.18 I think.

Following command fixed the issue on macOS Catalina

brew link php@7.3 --force

Instead of force linking you can also fix the problem in MacOS Catalina

by adding the php binary path to your bash profile e.g.:

echo 'export PATH="/usr/local/opt/php@7.3/bin:$PATH"' >> ~/.bash_profile
echo 'export PATH="/usr/local/opt/php@7.3/sbinbin:$PATH"' >> ~/.bash_profile

If brew link is not working for you, check your php version installed by:

ls /usr/local/opt/php*

Here, you will see a version as such:

/usr/local/opt/php@7.3/bin:$PATH

Should give you an output like:

/usr/local/opt/php@7.3:
INSTALL_RECEIPT.json        include
LICENSE                     lib
NEWS                        pecl
README.md                   sbin
bin                         share
homebrew.mxcl.php@7.3.plist

Now you just need to link that to your $PATH which can be done as:

echo 'export PATH="/usr/local/opt/php@7.3/bin:$PATH"' >> ~/.zshrc
echo 'export PATH="/usr/local/opt/php@7.3/sbin:$PATH"' >> ~/.zshrc
source ~/.zshrc

Note: I am using .zshrc because that is my terminal setup. If yours is bash, use accordingly.

You can check which version of php is now linked to your MacOS by running:

which php

This should give you an output of:

/usr/local/opt/php@7.3/bin/php

That's it. Now if you try composer update, it should not give you the extension issue.

This worked for me

brew update brew install php@7.3 brew link php@7.3 brew link php@7.3 --force

Hope it helps

In my case I had to simply

brew link --overwrite php

On 10 March 2020, It works for me:

brew install php

It is the only one command about PHP which work. So, I think that the commands shown in the last posts are deprecated.

Like @marc-alexander said, this is a bad practice. You should not use --ignore-platform-reqs option if you do not sure what you are doing.

I thought the option would ignore the platform requirements and install the specific version of the packages. But in fact it will ignore the platform requirements and install the highest available version of the packages.

So if you need the missing PHP extension, you should just install (or enable) it

Reference: ignore-platform-reqs installs dev-master instead of correct version

Original

If you do not need ext-zip (e.g. You just want to do some quick fix), you can use --ignore-platform-reqs option to ignore the requirements:

$ composer update --ignore-platform-reqs

i know this thread has true answered, i do those with this approach :

brew link php@7.3 it is showing hint to using
echo 'export PATH="/usr/local/opt/php@7.3/bin:$PATH"' >> ~/.zshrc echo 'export PATH="/usr/local/opt/php@7.3/sbin:$PATH"' >> ~/.zshrc
in terminal, echo 'export PATH="/usr/local/opt/php@7.3/bin:$PATH"' >> ~/.zshrc enter
in terminal, echo 'export PATH="/usr/local/opt/php@7.3/sbin:$PATH"' >> ~/.zshrc enter
next execution this : source ~/.zshrc
execution which php the results must show /usr/local/opt/php@7.3/bin/php
try again composer update, if show Allowed memory size of 1610612736 bytes exhausted (tried to allocate 4096 bytes) in phar:///usr/local/Cellar/composer/1.9.2/bin/composer/src/Composer/DependencyResolver/RuleWatchGraph.php on line 52 please change php.ini limit with memory_limit = -1
try search php.ini, type in terminal /usr/local/opt/php@7.3/bin/php --ini , the results must show: Configuration File (php.ini) Path: /usr/local/etc/php/7.3 Loaded Configuration File: /usr/local/etc/php/7.3/php.ini Scan for additional .ini files in: /usr/local/etc/php/7.3/conf.d Additional .ini files parsed: /usr/local/etc/php/7.3/conf.d/ext-opcache.ini
nano /usr/local/etc/php/7.3/php.ini, append memory_limit =-1,save
restart php
re-execution composer update.

Hope my answer can help you.

As other users already mentioned: This error usually means, that your PATH variable is not set up correctly, so some MAMP binaries are not found by the terminal.

Shell config

I use the following code in my .zshrc (or .bashrc) profile to set the correct PATHs for the current PHP version:

export PHP_VERSION=$(php -r 'echo PHP_VERSION;')
export PATH="/Applications/MAMP/Library/bin/:$PATH"
export PATH="/Applications/MAMP/bin/php/php$PHP_VERSION/bin/:$PATH"

Details

export PHP_VERSION=$(php -r 'echo PHP_VERSION;') this line fetches the PHP version from the current PHP interpreter. After that, you can access $PHP_VERSION in any shell script.
export PATH="/Applications/MAMP/Library/bin/:$PATH" this is a standard path that I need for MAMP integrations to work
export PATH="/Applications/MAMP/bin/php/php$PHP_VERSION/bin/:$PATH" this is the important part, which adds the correct phpX.Y.Z folder to the path list. This line uses the $PHP_VERSION which we fetched in the first line above.

Check

After adding the above snippet to .zshrc (or .bashrc) you need to load the updated shell profile by running the following command

source ~/.zshrc   # or ~/.bashrc

Finally, you can do a quick check so see if the PATH values are correct:

echo -e ${PATH//:/\\n}


# Output:
...
/Applications/MAMP/bin/php/php7.4.12/bin/    ← this line contains the PHP version
/Applications/MAMP/Library/bin/
...

The solutions above did not work for MacOS Big Sur. However, I cam to working solution:

Download latest tarbal at https://pecl.php.net/package/zip
brew install pcre2
fix a symlink, but check the version of your php (which php) and pcre2 (which pcre2) in order to install zip-1.20.1 in step 4.

ln -s /opt/homebrew/Cellar/pcre2/10.40/include/pcre2.h /opt/homebrew/opt/php@7.3/include/php/ext/pcre/pcre2.h
sudo pear install ~/Downloads/zip-1.20.1.tgz

Result: Installing /opt/homebrew/Cellar/php@7.3/7.3.33_2/pecl/20180731/zip.so install ok: channel://pecl.php.net/zip-1.20.1 Extension zip enabled in php.ini

Restart apache: sudo apachectl restart
Make sure that the location of php used by apache and the one used in your terminal is the same (MacOS homebrew!). Therefore, execute which php in the terminal and open a php file with the following command in your browser: exec('which php'). Make sure that in the httpd.conf file php path links the right php version!
